DeLonghi Lattissima Pro EN750MB Questions & Answers

You can change the time if you check your manual (hold the button for the amount of time you want coffee dispensed) and the temperature is the ideal temperature for coffee without losing taste. Sounds like a percolator would be more suitable for you and a milk frother if you want frothy milk.

Only Nespresso compatible

The message is only to turn the round knob to the « clean » position after using the machine, which will rince it prior to putting it in the fridge. A thorough manual cleaning is only required every few days to a week, depending on the milk quality. Soaking the black main part, or putting in in the dishwasher top right over a strong jet in the rotating arm will ensure good performance.

I definitely do clean and rinse all parts. Still having trouble. Thank you.

If the unit is a few years old: The brew unit (the part that slides back and forth when using the top lever) has a silicone ring that needs to be replaced. Dismantling the back, sides and front/top of the machine (just a couple of screws, the panels sort of slide out - see available YouTube videos) then remove the brew unit and unclip and slide out the inside cylinder. Ring to replace has about inch and a half diameter. Search for specific part online, or go to a plumber and find a suitable replacement - slightly smaller diameter but beefier. Reassemble. Will be dry. Or buy a whole new brew unit, about 50 pounds or 70 Canadian dollars. It will be the same, but with a new silicone seal…

Hello. I have the same issue. Did you manage to fix it? How? thank you

I rang customer care and they said £70 to fix but I got my handyman on it, he bought a part and sorted it.

Hi did you solve this problem, I'm having the same issue with mine, tried everything but nothing seems to have worked

Hi the coffee machine thinks it’s “system” tubes are blocked. Have you tried descaling yet & for good measure repeat the descaling process? Descaling takes approx 25 mins per cycle. I watched a YouTube video using vinegar. However if yr machine is still under warranty use a “proprietary descaling product“. If the descaling doesn’t work yr machine may need a service @ an authorised repair shop. Hope this helps, good luck.

Hi may I suggest trying a thorough system clean a couple of times. I use white vinegar, (look up how to on YouTube). Is yr milk canister plastic suction piece completely empty & repositioned correctly (no air lock)? Also check removable switch is fastened in place on milk canister. If you’ve been doing a lot of milky type coffees, there can be an internal building up inside the coffee machine pipes. Hope this helps, good luck.

hey mate i had the same problem was fixed by Ellis Electrical in Dandenong. You need what is called a brewing unit external link 

Hi have you tried descaling & a system reset if you’ve customised drink capacity or types?

Have you tried descaling the system?

Wow thst is a doosie, I'd suggest returning it to Nespresso for maintenance or replacement under warranty. Also just checking, have you put the milk jug back together properly? To also pinpoint where the problem is, does the hot water attachment work properly? Hope this helps, good luck.

Did you ever find a fix for this? My machine is now doing the exact same thing and I’m not sure how to go about fixing it. Thanks.

I called Nespresso and they took my machine away and fixed it. Have no idea what was wrong with it as they didn’t tell me

I have the same problem not impressed

I had the same..what to do?

I eventually had to take it for repair. Not cheap as they gave it a complete overhaul

Did you think to ask Delonghi?

Thanks Andy, DeLonghi referred me to Nespresso help since I purchased from them. The coffee specialist had me check for calcium flakes but there were none since I really do regular maintenance and, use filtered water. She had me run multiple Lungo shots and no flakes. She had me take apart the milk frothier head and soak all the parts for an hour in warm soapy water, which I'm doing now. I will post if this makes a difference. Thanks.

This seemed to work, I was surprised.

I believe your problem is a design flaw within the machine. The outlet behind the used POD storage which releases the excess steam is positioned in a way that makes the water fall past the drip tray and onto your bench. It's pretty pathetic for such an expensive machine to do this.

I believe you are correct Bam G. the machine continues to leak under the drip tray. What I did was to place self stick foam pads under the tray to slightly raise it so it fits more snug at the steam end. Helped a little, still not the best it could be...

If you just run a long black with no pod in it then that gives it a good rinse with just hot water after using it. Then you do a descaling once in a while. I've never tried to remove the spout.

Thank you. We run a short before every time we switch off the machine. We also do the descaling. We wanted to do the same as with the milk frother and give it a through clean every six months or so. But thank you for taking the time to suggest this.

I have the pro so not sure if the same will apply to you. On my machine, the tube has two little holes that are inserted into the top part where you control froth and cleaning. One of the holes in the tube has to align with a dot in the centre of the top part i.e the hole in the tube has to align with the spout where the milk comes out.

This resolved the issue for me. Hoping it’s as simple a fix for you.
