Delonghi EC 680/685 Dedica: a narrow and compact espresso maker with automatic dosing and a thermoblock for lovers of long coffee.

Compared to its more affordable competitors, the De’Longhi Dedica EC 680.M espresso machine looks like a classic limo next to a Hyundai Accent. There can be no doubt that its design is a success. It looks classy, respectable and expensive. The width of the full-metal body is rather impressive – only 15 cm, which makes it one of the narrowest espresso machines on the market. Due to these proportions, it can fit onto any table, taking up a minimum of space. As we know, width is the most critical factor in any kitchen.

The Delonghi EC 680M Dedica full-metal body pleases the ear as well as the eye. Metal provides better isolation of the pump, which is the main source of noise during operation. This model really is quieter than its “plastic” counterparts.

Delonghi Dedica EC680 should not be confused with Dedica Deluxe EC685 — check differences below 👇.

However, there is another nuance to the narrow body: as the metal portafilter is heavy and quite long, it causes the entire body to tip over when installed in the coffeemaker. In other words, you have to hold the body with your other hand to stop the machine tilting to one side. As the portafilter module is used more and gets ground in, this becomes less important.

By the way, although the holder looks like it is 100% metal, there is still a plastic part inside. In the very bottom of the portafilter there is a plastic dispenser that divides the coffee flow. But there is no need to worry – the plastic is good quality and the temperature of the coffee at that point is not too high. Still, if you want, you can unscrew the bolt in the bottom to remove that plastic part.

The cup stand, the drip tray, the steam wand and other silver parts are made of stainless steel, colored parts are made of some other metal alloy. The water tank and the lower black part are made of plastic.

Quick access to the operating mode by using the thermoblock instead of the boiler

The Delonghi EC 680 Dedica espresso maker is remarkable for its use of a thermoblock instead of a boiler as a heating element. I realise that sophisticated professionals of the coffee world will chuckle at this, but it gives clear advantages for a beginner who does not plan to delve deeply into the barista trade:

  1. It takes the coffeemaker at the most 30 seconds to enter the operating mode and be ready to serve coffee. Classic pump-type coffee makers for home use with a boiler (like the Delonghi ECO311) need more time to heat up – a minimum of 3-5 minutes is recommended.
  2. It can serve you two lungos at a time. In other words, the thermoblock can supply a much greater volume of water at the desired temperature than a boiler-type intended for home use. You can safely do a few lungos in a row. The same goes for the steam – it simply supplies more. By the way, this coffee maker includes a manual cappuccinatore with a flexible rotating mouting, which is much more convenient than many of its competitors.

The main advantage of electronic control is automatic dosing and portion volume programming

The second main feature of the Delonghi EC 680.BK coffeemaker is the electronic control. There are three buttons at the top of the front panel: one serving, two servings and steam preparation. Each of the first two buttons has a preset volume (approximately 40-50 and 80-100 ml, depending on the tamping of coffee grounds down into the portafilter), and the machine automatically stops the feed upon reaching this level in the cup.

In addition, if you simply press and hold, you can program your favourite volume for each button. That is to say, the “two servings” button can deliver any volume you want, not just two times more than the standard. For example, you can program it to serve a ristretto (20ml in the classic recipe) or lungo (60+ ml).

Electronic control advantages:

  1. Program an automatic shutdown time: 9 minutes, 30 minutes, 3 hours.
  2. Program your coffee temperature – there are three levels and medium is the default. This may be relevant for those who like it hotter, though, believe me, the right temperature is medium. In order to make the coffee hotter, it is necessary to let water run through the brew group (make one portion without coffee) and a cup (heating the cup a little).
  3. Programming for water hardness. This affects the frequency of the descaling procedure. Depending on water hardness, the machine turns on this indicator more or less frequently. The machine simply counts the number of served portions, as it cannot define the actual amount of scale. The harder the water, the more often the machine will turn on the alarm light for the descaling procedure. At the maximum level of water hardness, the Delonghi EC680 M Dedica requires descaling approximately every 200 servings. As a matter of fact, all coffee machines are similar in this regard.
  4. Built-in descaling program. It is not fully automatic, as in most cases – it is necessary to be near the machine and carry out various actions, which are described in detail in the manual.

Cons

Everything as standard for this class of espresso machines:

  1. The passive cup heater only works well if the machine is well heated (after 5-10 minutes of warm-up and/or 1-2 served cups). This is always the case.
  2. The cup stand quickly gets covered with scratches, which is also common.
  3. The cup stand is too narrow to accommodate two large cups, which is the price to pay for the compact body. This is relevant for couples who love big servings.
  4. The combined plastic tamper and measuring spoon is rather weak. No, it won’t break after a month of use, not even a year, but it’s much more pleasant to work with a metal one, which you can buy separately (51 mm in diameter).
  5. The filters have a double bottom (the same are used in the Delonghi ECO 311). They are more sensitive to the type of grinding than valve ones (for example, in the Saeco HD 8325/47). It is not recommended to use the extra fine grind. This can block the space between the upper layer (with many little holes) and the lower layer (with one centred hole). It is better to lean towards medium grinding, give or take. Remember to rinse the filter after use. As a precaution (once a month or two), it is worth soaking them in citric acid and then rinsing with fast-flowing hot water from the tap.
  6. The machine needs some time to cool down after steaming the milk and before making the espresso. This is because it doesn’t automatically drain water from thermoblock like Krups Calvi XP3440 does, for example. By the way, Calvi is another option if you are looking for a fast and narrow espresso machine, but less automated and with a lower price tag.

Color range

The Delonghi Dedica EC 680 espresso maker is available in three colours:

  • Delonghi EC 680.BK – black with chrome elements
  • Delonghi EC 680.R– red with chrome elements
  • Delonghi EC 680.M– silver
  • DeLonghi EC680BMC – is a gift set which includes a silver EC680M machine and two cappuccino glasses

Once again, I would like to draw your attention to the fact that all these models have full-metal bodies. I will repeat myself and say that they look classy and sophisticated.

Updated EC 685 series review (and comparison 680 vs 685)

In 2017 Delonghi made some changes and launched new models with 685 index and called it Dedica Style in Europe and Dedica Deluxe in the US. In the new EC685 model range they added a white color (EC685W, not available in the UK) and made only two functional changes.

So, EC685 vs EC680:

  1. Steam wand on 685 is equipped with regulator ring, the same that we saw on Delonghi ECP 35.31 and ECP3630. In the down position it just froths the milk, as usual. In upper position it only heats up and mixes the milk, making almost no bubbles. This mode could be useful if you like less milk foam in your cappuccino, or if you want to make hot chocolate for kids. For technical details see my comment below.
  2. EC685 has second mini drip tray under the cup stand. So you can put higher glasses under the holder. Many owners of espresso machines use following hint, if they want to use higher glasses: remove the main cup stand, and put cup directly on the floor of the drip tray. That allows to gain extra 2-3 cm. Delonghi on EC 685 M/BK/W/R models put the metal plate on the bottom of the drip tray and now maximum cup height is officially 12 cm.
  3. All else being equal if compared to the EC680.


So it's up to you to decide if it's worth paying more for the newer model. My new price comparison tool below (updated several times a day) might help 🙂

Similar models

Delonghi EC680 has a “clone” – SMEG ECF01. It is exactly the same machine without any functional differences. Just outlook is slightly changed by SMEG designers, the upper part is made of plastic (not metal alloy like on Delonghi EC680/685) and the price is doubled. There are black SMEG ECF01BLEU, blue ECF01PBEU, red ECF01RDEU and beige/cream ECF01CREU models in stock:

For the US market Smeg has different indexes: ECF01BLUS (which is short for “Black” and “US”), ECF01PBUS (“pastel blue”), ECF01RDUS and ECF01CRUS respectively.

EC680 also has two close relatives with the same essential components – the Delonghi EC 820/850/860. It is hard to tell from their appearance, but they have a similar thermoblock, exactly the same pump, the same metal portafilter with filters and a front water tank (1l). Ignoring the appearance, the key differences are:

  • The model 820 is mechanically controlled, it does not dose automatically and does not program the volume of a serving. A more classic model for creative people, and also a bit more reliable.
  • In addition to everything that the 680 includes, the EC850/860 also has an automatic cappuccinatore with an integrated 0.5-litre jug that allows the height of the milk froth to be adjusted. De’Longhi EC860 “knows” how to make a cappuccino or latte in one touch. But, of course, you first need to tamp the coffee and fit the portafilter.

My Review Conclusion

The Delonghi EC 680.m/bk/r Dedica espresso machine is a compact, reliable and classy solution for coffee lovers who want some kind of automation (automatic dosage, serving size memory) and speed (a heat block that is ready for operation in 30 seconds), but on the other hand do not want to be completely detached from the process (as with automatic bean-to-cup machines). They want to be able to influence the taste directly, forming a coffee puck according to the rules of the craft and their personal preferences.

It is also important to understand that the price you pay for the Dedica is higher than for coffeemakers such as the Delonghi ECO 310/311, because it has a thermoblock heating element that makes it possible to deliver larger portions of coffee. If you prefer classic, small espresso shots and do not need automatic dosing, you are overpaying for the design and compact body alone.

Finally, if you want to get a good espresso from this machine, I highly recommend using fresh beans and grinding them with a decent coffee grinder (no, the cheapest blade grinder is not the best choice).

  • Great review! I recently bought this machine second hand and it came without the frother steel tube / regulator ring. Does this make the frother unusable? I can't seem to find a spare for the model anywhere.

    • Hi, Nik, and sorry for my late reply. This part is needed to evenly distribute the hot water over the coffee (thermoblock output is just a one hole) and it may leak without it as well. You can choose among the boiler-based Delonghi models, they don't have this gasket.

  • Dimity, We have a EC685 which we love. Last week I purchased beans instead of ground coffee. We have ground the beans, followed the instructions for filling the filter holder but the water just drips out and the coffee is weak. When we remove the filter holder it is very wet. We have done a coarser and finer grind with the same result. Cheers

    • Hi, Sue! And sorry for my lare reply.

      Freshly ground beans can be more absorbing, indeed, which can lead to a watery puck. As well as different coffee beans could give different results, did you buy beans of the same blend as you used before (when used ground coffee)? However, could you specify if the coffee drips (drops) or flushs rapidly?

  • Hello Dmitri,
    I've not been able to acquire a bespoke single bottom filter, but I did remove the hole from my own double bottom filter.
    The result seems to be that the top filter now gets blocked. It is not man-enough for a finer grind?

    I will purchase a Rommelsbacher EKM300 grinder as you recommend.

    • Hi, Ian.

      By "top filter" did you mean upper filter in the filter basket? Sounds strange, because if it didn't get blocked before your nodofication, then the absence of bottom hole didn't affect it...

      • Thanks Dmitry,
        My view is that the small hole in the bottom filter produces such a back pressure that the holes in the top (main) filter are quite large. Therefore applying more tampering simply produces a clogged mesh. Grinding a coarser coffee produced weak coffee.

  • Hi Dimitri,

    Can I use filter basket for 2 cups if I want to make just one cup of coffee or I must use single cup filter?

    Thanks in advance for you explanation.

    Alex

    • Technically, you can do that, but putting 50% of coffee into the 2cup basket will lead to dirty grouphead - the coffee puck be watery after brewing even if you tamp it well, and everything will be covered with the wet ground coffee.

  • Hello!

    I love this machine, but I readed some reviews on amazon that rates it with one star and tells the machine is overheating after one espresso and should wait to make another one. Somethimes, family or friends comes to my house and then I want to make 6 or 8 coffees at the same time: i.e. 4 times the double basket. Can I trust on this machine, or I will wait for decrease the temperature? (sorry for my bad english)

    • Hi, Carles. No worries - my English is even worse :)

      I checked briefly latest reviews on amazon, and didn't find any topic about overheating after _espresso_. Probably they reffered to overheating after cappuccino.

      That's true, since this model doesn't have a drainage, it need some time to cool down after steaming the milk to be ready again for coffee. That's because for steam the machine needs higher temperature than for espresso. You can speed the proccess up by simply letting some water out - the fresh cold water will come into the thermoblock.

      There should be no problems (or I know any) about overheating between espressos.

  • Hi, thanks for your nice review
    I got from my friends some bad experience with 685 version , what do.you think the disadvantages of it compared to 680??

    • 680 = 685 except few improvements, which are described in the review. The coffee quality and all the internals are the same.

  • Hello! I am wsnt to buy my first home espresso machine and I can't decide between the EC 680 and the ECP 3630, the prics at this moment are very similar and I would be using it mainly for capuccinos and lattes and a few espressos.
    Which one would you recommend me to buy?
    Thank you!

  • Merry Christmas and thanks Dmitriy for a very informative review and website. I stumbled across this review while looking for information about the SMEG ECF01 (& very surprised to find it’s a clone of the Delonghi), and after reading this review and following links to your other Delonghi and Krups reviews have learnt a lot about thermoblocks, boilers, pumps, grinders, pressurised filters and useful hacks, in a pretty short time!
    We currently use a “Little Guy” stove-top espresso maker. Even though it generates less pressure than the ones reviewed here, I’m able to produce good crema and micro foam, through a bit of practice and experimenting. So I originally felt it would be important to be able to reproduce those things authentically with my next coffee maker. I’ve since learnt from you that good tasting coffee isn’t all about the crema, and that the wand on the EC680 doesn’t generate “genuine” micro foam, but is more reliable for the novice.
    So, leading from that I have a few questions I hope you can answer. Firstly, I am still drawn to the SMEG, due to the styling and also because there are some specials in Aus at the moment that don’t make it too much more expensive than the Delonghi (SMEG = $374, EC685 = $299) and SMEG are also running a promotion which includes a stainless tamper, stainless milk jug, cups and ground coffee, so:

    1) You mention the EC680/5 is made from plastic, with a metal wrap. The SMEG advertises it’s construction as “metal wrap with coloured polycarbonate housing”. Do you think that means it essentially still the same plastic insides as the EC680/5?
    2). Both the EC685 and SMEG say they have an adjustable steam wand. Sorry if you covered this but I’m still a little unsure. You mention it “doesn’t make it easier” but would that allow me to dial-back the auto-frothing function and allow me to create micro foam? If not, sounds like the Rancilio-Silvia mod should also work on SMEG and would be my best option?
    3). I’d like to try it without the pressurised portafilter, I’m guessing the SMEG will also accept the non-pressurised holder from the ECO series?
    4). What’s your knowledge of replacing thermoblocks? Is it something someone with patience and care can do at home, or are those coffee machines essentially a throw-away once the thermoblock fails (noting your comment about the steam valve being more likely to break first)?

    Thanks again. I’ll be coming back here soon to research how my Sunbeam Cafe Series grinder compares to the models you suggest for the EC680/5 !
    Peter
    Canberra, Australia.

    • Hi, Peter!

      1) Yes, I think it's the same: plastic frame with a layer of metal on it. Not sure about the top rounded part of Smeg, which they changed.

      2) Only the EC685 has an adjustment ring, SMEG doesn't. Probably, they mean something different by "adjustable". Like the fact that the panarello can changes its angle?

      Anyway, this hot milk/foam ring doesn allow you to "go back" from amateur level to professional frothing (microfoam). You can take off the outer metal part and try to froth with inner plastic/rubber spout, which is located underneat it. However, it's still not a normal steam wand. And yes, the Silvia mod should work on Smeg as well.

      3) Yes, filters from other Delonghis and noname 51mm baskets baskets from Aliexpress will work. On EC685 you need to put out the inner plastic part from the holder to make it fit. But! Smeg changed the design of the portafilter a bit, so may be they changes this as well. I didn't check this moment.

      4) You can fix or replace the thermoblock block of course, however, usually it's not much cheaper (parts+works, even here in Russia) than to to buy a new espresso machine. Surely you can do it by yourself at home, if you are handy enough.

      These machines are quite reliable, so I wouldn't worry about it. Factory defects reveal themselves in first weeks and are covered by warranty. If everything is OK from the start and the machine is descaled regularly, then it will last long.

      Overall, this offer on SMEG + accesories seems to be a good deal.

      Thank you, Peter, for congratulations. Wish you good holidays and happy new year. With your new machine :)

  • Hi, Dimitry! Great that I came across your website! Currently I am in search of a new espresso machine as my last Saeco Poemia has given up (aluminium holder broke while trying to make a cup of coffee), just fell of due to one of the two "shoulders" holding the thing cracked and came off. And it is my 2nd machine that happened to have exactly the same breakdown... There is a question that bothers me while looking the replacement:
    Will I be able to put in the filter of EC685 same amount of coffee as fit in Saeco to receive the desired strength and taste as per water used (around 150ml)? Can you please advise the difference in the volume of Saeco and EC685 filters?

    • Hi, Costas. Delonghi (2cup basket) has a max. capacity approx. 14-15 g, while Saeco's one has 17-18 grams at maximum. But! These are measurements from my notes from two different tests. Different coffee beans and different grinders were used, so it may be not very accurate. However, Saeco definetly has a slightly larger capacity.

      P. S. What was the first machine with the same failure? Also Poemia?

  • Hi Dimitry, I have owned a EC680 for 4 years, however experience inconsistent steam when frothing milk - sometimes the steam is strong and other times very weak. Recently on odd occasions I have noticed that after around 10-15 seconds the steam stops completely, so I cannot finish frothing the milk. Do you have any explanation as to why this happens?
    Thank you and Happy New Year!

    • Hi, Jon, I’m sorry for my late reply. Hope it still can help you.

      Most probably it is because sometimes you don't rotate a steam knob till the end, till fully open position. There is a limit switch in the knob (at maximum position or near it) that switchs on pump, it starts working in intermittent mode (1 sec - pause - 1 sec - pause - etc), helping to create stronger steam. Without the pump, the steam is leaving thermoblock under the "normal" pressure, which results in a weaker steam.

      • Thanks for your reply Dimitry. I do however rotate the steam knob as far as it will go. Sometimes the steam comes out strong and sometimes weak - I can hear the intermittent sound of the pump. The really frustrating times are when it starts to froth the milk and then completely stops.I try to turn off then on again and nothing happens. I wondered if there is something blocking the flow of steam - the machine has recently been descaled?
        Thanks again.

        • "I can hear the intermittent sound of the pump" every time?

          "it starts to froth the milk and then completely stops.I try to turn off then on again and nothing happens" this may be caused by overheating or by time (machine stops after minute or so of frothing to prevent overheating).

          I don't think that descaling could be the reason, unlikely. However theoretically some small particle of scale could block the tube coming to the panarello. By the way, do you use soft water? I ask because there was similar problem on Delonghi's super-automatic machines, when after descaling with VERY SOFT water they stop producing steam. The problems was caused by the fact, that very soft water didn't fully washed out the descling liquid, which created a layer on the thermoblock tubes. As users reported, running another descling cycle with a hard water (and with no descling liquid) helped them to solve the problem. Unlikely you have smth similar, however you may give this idea a tray, if you have very soft water.

  • Hi Dimitry. Many thanks for this great review. I found a EC685 for 120€ (approx. 140$) so keen to buy one.

    Any recommendations for a grinder which will be a good combination with the EC685?

    Also, is there a tamper included in the package?

    • They put a plastic spoon slash tamper in the box. But it's poorly made. For better results it's better to buy a heavy metal tamper, you'll need a 51mm tamper.

  • Have just purchased a delonghi E 685.
    Followed all first use instructions and coffee only drips out, resulting in a coffee with no cream and takes ages! Devastated! Don’t know whether to replace it as faulty or try a different machine.
    Any advice?
    Very best
    Steve.

  • I'm considering purchasing the Euro version of the EC685 for use here in the States (at a really good price of under $150). Can you confirm the European model can run on 60 Hz and that with the machine operating at 1350 watts, 220 volts, it would only draw a little over 6 amps?
    I will be putting on my own NEMA plug consisting of two hot leads (110V ea) and a ground. Any assistance you can provide would be of great value to me.

  • Thanks for the great description.
    I need a little help. I'm wondering which one of the followings is better:

    1. Delonghi ECP 35.31
    2. Delonghi EC685M
    3. Delonghi BCO 421

    I'll be grateful if you help me out. Which one would you pick up if you were me?

    • Hi, Iman.

      BCO is a combo machine (drip + espresso), so no need to choose if you want an espresso maker.

      Between the ECP and EC685 the choice is basen on following:
      1) ECP: less comfortable to make cappuccino, slower, more robust, but more durable, and it will be better in future in case you will decide to upgrade (single wa;; baskets, bottomless portafilters - all that kind of stuff)
      2) ECP685: is faster, smaller, more comfortable cappuccino, perfect and universal choice if you are just an ordinary user and not planning to "go hard" with espresso.

  • Hi Dmitriy,
    Thanks for the detailed review provided. I bought a Delonghi EC685 and after 3weeks of use, i noticed grey powdery residue at the rim of the portafilter and the rim of the basket after removing it. Do you know what is the material of the portafilter and basket? The powder looks like metal powder due to wear and tear. Could you advise? Thanks!

  • Hi,

    I have a question about the grind of the coffee - I bought kg79 delonghi grinder with dedical machine and after a lot of testing I think the best grind size is 5 (out of 15 settings) - on very fine grinds the machine was spluttering coffee and really struggling... That is not an issue I hope?

    • That's a matter of taste, of course, but I think that even the finest grind setting on KG79 isn't fine enough for espresso on Dedica.

      P. S. It isn't something bad when machine is "struggling".

      • One last point as per your cons points above:

        The filters have a double bottom (the same are used in the Delonghi ECO 311). They are more sensitive to the type of grinding than valve ones (for example, in the Saeco HD 8325/47). It is not recommended to use the extra fine grind. This can block the space between the upper layer (with many little holes) and the lower layer (with one centred hole). It is better to lean towards medium grinding, give or take.

      • interesting, anything from 1 to 3 just will not go through the machine and it barely drips anything, so that is not good. Taste is not great of course, the volume is nowehere near a single or double. My version of dedica just won't have it anywhere below 4 clicks... I found that some people were also struggling with this and found a few answers suggesting that teh grind is too fine
