Delonghi Icona Eco 310 and 311 Espresso Coffee Makers Review

Comments: 31↓ specifications & manual ↓↓ Updated: ECO311 vs Scultura ECZ351 ↓

Delonghi ECO 311 espresso coffee makers replaced the ECO 310 Icona model that had been produced since 2010. In fact, these two models have almost no differences. All inner parts remained the same. However, this can be said about almost any other espresso coffee maker of this brand.

It is Simply a Matter of Marketing. The Manufacturer has Decided to Update a Product Line Every 5 Years as They do in the Automotive Industry.

So, what exactly has changed in the De’Longhi ECO 311 in comparison to the 310th model? Well, at least two things:

  • Now there is an automatic cutoff function. After 9 minutes of downtime, the machine turns off. This feature has been introduced to meet strict European standards of electrical energy consumption.
  • The ECO 311 is completed with a portafilter of a new design. However, the last produced ECO 310 models already came completed with the new portafilter. Whereas, the first 311-s sometimes included the “old” one. In general, this is exactly why any manual has the following clause: “a manufacturer in its sole discretion and without a notice may change the complete set, appearance, country of production, and technical characteristics of the model”

Important note. Despite the fact that officially Delonghi 310 is called “15-Bar-Pump Espresso Machine”, you should not be misled by the word “machine” in the title. It is not an automatic coffee machine, it is a coffee maker. That is, the automation here is at a minimum level. You will have to grab ground coffee (or preferably to grind it just before brewing), put it in the portafilter, tamper it, warm up the coffee maker, and manually turn on the water supply; then, dismantle the portafilter and clean coffee residue off it. Just like any barista would do. Cappuccino should also be cooked manually.

I would also appreciate your starred review at the end of the article

What is the “New Delonghi Portafilter” and What Makes it Different From the Old One?

  1. Now, there is a filter fixing spring for a coffee filter inside the portafilter. Now it is firmly fixed in it, making it easy to throw out the coffee grounds. As a result, there is no need for a mechanical filter holder. Therefore, the thrust has been removed from its design.
  2. The coffee-cream filter system has also been changed. Like any modern coffee machines and coffee makers, Delonghi 310/311 is equipped with a special filter. With it, even an amateur would be able to get a nice coffee foam and a rich taste with any grinding and with any grain. A filter in the old portafilter was designed as a plastic flap (a similar solution is still used now in a Saeco Poemia coffee makers), the new portafilter has baskets with a double floor. Its effect is about the same, but there are less plastic elements contacting coffee, which is good news.
  3. The portafilter feels heavier, now it feels more like portafilters used in professional espresso machines. Nevertheless, we should not delude ourselves into thinking that this effect is achieved by the use of other materials. The reality is it’s a metal cylinder-sinker hidden in a handle of the portafilter.

What do Coffee Makers Series 310 and 311 Have in Common?

De’Longhi ECO311, just like ECO310, has a full metal body. The design has not changed, it is made in retro style and feature different colors: red Icona ECO 311.R, white 311.W, black 311.BK, and beige 311.BG:

Red, Beige, Black and White De'Leonghi ECO311 espresso makers

However, in North America less color options are available. In the UK and other European countries, you can find models of all colors.

In Europe, there are also modifications in olive and light blue color called “Azur” under the ECOV 311 index (a prefix V means Vintage). They differ only in terms of body colors and in the fact that these models still include old types of portafilters without fixing spring made of brown plastic. In addition, Icona Vintage leather logo key ring goes with it as a gift (but do you really need it?):

Big stainless steel boiler for 180ml gurantees that the temperature will be stable during coffee extraction. Boiler power of 1,100 watts and standard Delonghi pump is enough to prepare a 2-2.2 fl oz (60-70ml) of coffee at a required temperature and a pressure of 9 bar. Further, the temperature falls below 365 K (92°C) as the machine informs us about that with the light turning off. This is sufficient for the preparation of espresso and lungo in canonical volumes. However, you can wait 20-30 seconds for the boiler to heat up the water and continue.

This is the parameter that distinguishes Delonghi ECO311 Icona from more expensive coffee makers with thermoblock as a heating element (such as EC 680/685 or EC 820.B). They can maintain the desired temperature and pressure for longer. At the same time, it is not inferior to its direct competitors. Saeco HD 8325 Poemia has even weaker boiler of 950 watts and 110ml.

Delonghi 310 and 311 both have a manual cappuccinator of "pannarello" type

Delonghi 310 and 311 both have a manual cappuccinator of “pannarello” type

The coffee maker features a function that lets you make any espresso-based milk beverages with a manual cappuccinator-pannarello. Of course, it does not turn 360° as it is the case with expensive portafilter coffee makers, but it deviates from the cup stand to the side at a large enough angle so that you can whisk the milk in a pitcher or a glass. It also makes it possible to turn espresso into Americano (if you simply run a large amount of water through the portafilter, you get lungo).

On top of the coffee maker, there is a chrome platform with a passive cup heater. It copes with its task quite well, if you reheat the coffee maker, let it steam out for 5-10 seconds, and wait about five minutes, or better yet, make 1-2 servings “in idle.” Otherwise, the upper plate doesn’t get warm enough and it takes too long for cups to warm up. However, it is also advisable to do so to warm up a group (portafilter), which has a positive effect on the extraction of coffee.

The water tank (50 fl oz) is in the rear part of the coffee maker and it is made of transparent plastic. This makes it easy to monitor the water level and refill it without removing the tank itself (but if necessary, it is possible to take it out). The plastic tank itself, and all sealing rubber components are made of high-quality materials and do not affect the taste and odor of water, as it is the case with some cheaper competitors, e.g. Mr. Coffee models.

Unfortunately, one problem of the 310th model hasn’t been addressed. Metal cup stand located right under the portafilter is not fixed in place. Therefore, when using light cups, they vibrate and clang when the pump works and the shining stand gets scratched. Buyers complained in their reviews about it. The solution is either you don’t pay attention to the noise, or use heavier cups, or just put a cup on a napkin.

Conclusion of the Review and Similar Models: Scultura and ECP

De’Longhi ECO 310 or 311 Icona are good choices if you care about a design of your future coffee maker and need a simple coffee maker for home use with a pressure of at least 9 bar.

Full Metal Body, “New Portafilter,” and Design Explains Higher Price Tag Compared to Cheaper Delonghi Models.

However, in North America, the 311th model usually costs more than “old” model of the 310 series. As I mentioned above, the differences are purely symbolic, the quality of coffee is not affected. Therefore, it is reasonable to choose the red De’Longhi ECO310R or black DeLonghi ECO310BK in this price range. You will get an excellent coffee maker which will serve you for years making you delicious espresso. However, of course, it requires proper maintenance: make decalcification once or twice a year, including dismantling and cleaning the filter. New ECO 311 series requires decalcification, filter cleaning is not necessary.

Delonghi ECZ 351 BK pump espresso machineIn some counties Delonghi also sells ECZ models. It is black ECZ351.BK Scultura, beige ECZ351.BG, white ECZ351.W etc. All espresso machines with 351 index have all the same characteristics as ECO311 models. Except the design, which became more vintage and has less metal in coating (upper colored part on Scultura is made of plastic, it’s not the metal as on ECO311), and the tamper, which is now a separate accessory (on the ECO311 it was built-in). Sizes changed a little due to it, however insignificantly, just ±1cm. All esle buing equal and these changes does not affect the coffee quality.

If the design and appearance are not important to you, it would be wiser to buy Delonghi EC 155 or new Delonghi ECP 31.21, which is cheaper becuase of plastic finishing and different controls. Technically, they are identical. However, EC 145, which is even more cheaper, is not worth your attention, since it has no pressurized crema filter, which, in my opinion, is important for a beginner. Well, if you are not an amateur, but rather a professional, it is unlikely that you consider buying one in this price range.

P. S. Want to know more? Look how I dissambled this model and compared it with other espresso makers.

  2. How big cup of coffee can I make with single load on this machine?


    19 Mar 17 at 4:30 am


    • Technically, as big as you want. But after ~70-80ml the temperature will become too low for a good coffee extraction. So with one brew you can make 2 good espressos or 1 good lungo on it. Or you can stop for while, wait for water to heat up again and continue. But I don’t recommend to do like this – coffee will be overextracted and has a poor taste.

  3. Hello! What can you tell me about the Kenwood ES 024?


    1 May 17 at 7:54 am


    • The Kenwood ES 024 kMix and ES 020 are the same thing, and they are both analogues of the DeLonghi ECO 310, just with a different design and a smaller water tank. In some countries they are sold with the old filter baskets. In other words, Kenwood = Delonghi, choose the design you like.

  4. I have Delonghi 311 Red. The right tube for milk frothing is leaking when I prepare coffee. How can I fix it?


    9 Jun 17 at 7:12 pm


    • Probably the steam opener (big twisty knob) on the top on the middle is not tightened. Try to tight it up!


      14 Jun 17 at 3:15 pm


  5. How can I extend the time before it will turn off? De’Longhi ECO 311
    It shutting off after I make the cup of coffee and waiting for the steam to head up it go in to eco mode and shut it self too soon. It was working just fine before I was cleaning I’ve must off accidentally change the programing by pushing the power button on some sort of order and that change the timing! Thank you


    24 Jul 17 at 7:00 am


    • Hi, MJ! Delonghi ECO 311 doesn’t have the programmable auto-shut off function, it’s always 9 min. Even if for some markets they add this function (which I doubt) the minimum time will be 9 min. And 9 minutes should more that enough to heat the boiler up to the steam temperature.

      That’s why I think that the problem with your Delonghi is not because of the eco mode, but becuase of the overheating. There are emergency thermostats on Delonghi, they are installed on the boiler and on the pump and they will shut off the machine, if something is going wrong (e.g. the temp is too high or the voltage). If I’m right, you should fix it in service, it’s under the warranty. Sometimes descaling will also help (scale could be the reason of overheating).

      However, how much time does it take between switching to the steam mode and the moment it is shutting off?


      24 Jul 17 at 1:25 pm


  6. Ok I see, Thank you for your time, I will descale and see if it will help.
    If not I will send this to the service.
    Thank you again:-)

  7. Judging from ECO 311 & ECP 35.31, which one is a better take, in terms of the quality of coffee produce.


    30 Aug 17 at 3:22 pm


    • In terms of black coffee they are equal. Basic espresso would be the same. Just ECO311 will keep warm a little bit longer (because of full metal body), but it is very negligible distinction.

      In terms of quality of milk foam for cappuccino, ECP3531 has steam wand with regulator that helps to heat the milk, not frothing it. On the other hand, I personally think that the shape of the steam wand is a little bit more comfortable on ECO311.

      So, if you don’t need special mode for ‘not frothed hot milk’ and the prices are equal I would choose ECO311.


      30 Aug 17 at 4:58 pm


  8. Hey! nice review here, may I know if the new 2-cup filter(ECO311) could be fit into the old handle(ECO310)?


    10 Oct 17 at 1:41 am


    • Hi! Thanks. It should be no problem.


      12 Oct 17 at 4:52 pm


  9. Hi. We have just had to return a new Scultura ECZ351 model for poor crema performance with the all-metal coffee filter (and yes we tried all the permutations of grind and tamping etc). We have quite a lot of experience with deLonghi models, and have found the plastic/rubber flap type filter gives superior crema. The Scultura was not bad, just not as good as the 10yr old model we are going to replace. Thanks to your excellent review, I now know that we need the 310 model not 311. Cheers

    • Yes, ECO310, EC270, and EC155 are the only models left in stock, which have the old filter. You could also check 311 Vintage (index ECO311V), on some markets they have the old filter as well.

      Have you tried to fit the old filter from your old machine into the Scultura’s holder?


      2 Nov 17 at 8:55 am


  10. Yes I have tried this, but it doesn’t fit. Might do if the wire spring clip was removable, but even then I suspect the plastic ‘knob’ underneath would foul something in the new filter holder?
    The new stuff LOOKS really nice and is simpler to use, but from the last few days experience the older version produces a good crema much more readily. Progress eh? I will look up the other models you mentioned, and might go for another 310 as we already have one. Thanks for your help.

    • Thank you for your feeback. I’m not 100% sure, that’s why I asked. I tried vise versa (put the new filter in the old holder) and it worked for me. As well as the very old one (unpressurised filter from the Delonghi EC145 into the new holder), worked as well.

      The spring clip is removable (see photo: ) and the overall height is the same. So I assume it could work. However, the filter would not be fixed.

      ⚠️For all readers: if you personally tried to put the old filter into the new basket – please write if it works fine (or not).

      P. S. Colin, I understand that you get used to Delonghi’s makers, however Saeco Poemia/Gaggia Gran is also a great choice, especially in terms of crema. Just in case 🙂


      3 Nov 17 at 12:23 pm


  11. Could i use the portafilter and filter for the 310 on the 311? Will it fit?

    Shang Yang

    8 Nov 17 at 8:40 am


    • Hi, Shang! Do you mean not only the filter basket, but whole portafiler (like on photo)? Yes, 100% you can.

      If you meant only filter basket, then as I mentioned in the comment above, I never tried to do it. However I’m 99% sure that it will work.


      13 Nov 17 at 10:30 am


  12. I just received my ECO311 and have not yet made a coffee, but in examining the filter baskets, the holes are SUPER tiny where I’d put the coffee into (the cup part), and virtually non-existent from the bottom side. As in, it does not look like there are holes at all. Is this a defect or all is as it should be? I’ve made coffee on Gaggia/Baby Gaggia, and one other kind of machine and never encountered this. I’m predicting an overflowing mess! Thanks in advance for your advice.

    • That’s the way it should be, don’t worry. It is so-called pressurized filter basket, while on Gaggias you had classic unpressurized ones.

      The tiny hole on the bottom limits the flow and (consequently) the pressure. That allows you to get full taste and crema (however crema is rather fake on pressurized filters) even if you don’t tamp coffee well and use unappropriate grind level. Without it you will get weak taste, just a hot water with coffee flavor. I mean, not you personally, since you had no problems with Gaggia Classic. However it’s useful for the beginners.

      If you want you can buy classic filter basket for this coffee maker. The part number is 7313286069 or search for baskets made for EC145/146, it will fit into the 311’s holder. By the way, you even can unscrew the bottom part of the holder to make a bottomless portafiler.

      P.S. The upper holes are made so tiny because the manufacturer tried to avoid the situation when coffee particles stuck between the down part and the upper part. Still it’s better not to use super extra fine grind with such filters.


      22 Nov 17 at 5:29 pm


      • Thanks so much for your detailed reply, Dmitry! I’m about to make my first morning coffee. Here goes!… 🙂

  13. Between Eco311 and EC 685, which should I buy? I drink Cappuccino mostly.


    30 Dec 17 at 2:19 pm


  14. Hi
    I have ECO310.BK.
    Can I use new portafiler?
    Is it compatibile with old ECO310.BK? (size, dimensions,etc)


    2 Jan 18 at 3:23 pm


  15. hi there, i am contemplating between ECO311 and ECP3531. I am consider a total newbie using machines such as this and i am wondering as far as price is concerned, which would be a better choice for someone that is totally on an entry level in learning to make milk based drink?


    20 Jan 18 at 3:53 pm


    • If the price for the 311 is similar in your country, then I would choose it. After all, full metal body is better, I also find controls (three buttons) and water tank to be a bit more comfortable.

      However, the ECP3531 is still good. If it’s cheaper and if you don’t want to spend extra money, then I see no reason to overpay for the ECO311.

      P. S. The “advanced steam wand” with hot milk/foam regulator (on the ECP3531) is useful only if you really want to prepare hot milk or make drinks like flat white. For classic cappuccino and latte it’s useless, so I wouldn’t consider this.


      20 Jan 18 at 4:44 pm


  16. Hi Dimitry, we have a Delonghi 310.R , and the steamer knob has ‘jammed’ . We haven’t used the frother for a while and it may have seized up! We have been able to get the knob off in order to try and use a bit of force on the spindle itself, but still not able to get it to turn to froth position. Help!!

    4 Feb 18 at 4:01 pm


    • You have the same counstruction on your machine, right?

      Could you please clarify if the problem is that you could not rotate it (the knob or the spindle) or you can rotate it but it does not open the steam wand?
