Question about DeLonghi ESAM3500 Espresso Machine & Coffee Maker

Delonghi esam3500 leaking

I have had my DeLonghi Magnifica ESAM3500 for a number of years making great coffee. Recently I have noticed water collecting in the tray but I am still able to make espresso and lattes. I have seen many posts about this recommending to replace the o'rings but I haven't seen a detailed explanation of how to take the machine apart or where the o'rings are. Could you point me to something I can refer to? I would like to take care of this before the leak gets worse and won't be sable to make coffee anymore. Thanks, Nick

SOURCE: Delonghi ESAM3500 with not froth milk. Water will


Understanding how the frothing mechanism functions is half the battle in figuring out the solution. It's a simple vacuum type system. No doubt you've read about checking the orings. This is definitely the first thing to check however if this is not the reason then consider the following.

The larger of the white tubes that has the red and black oring inserts deep into its port on the tap. Why? It pushes steam past the milk pipe directly into the chrome frothing tube which causes a vacuum essentially drawing milk up it's hose creating the froth. What you can't see without further investigation is that on the underside of the tube centered between the red and black orings is a small hole. This hole is responsible for drawing the milk upwards. If this is blocked, and it probably is then no milk and no froth. Use a really small screwdriver to carefully clean the white tube both from the front and the little hole underneath.

So in conclusion. Any air leak between the red and black rings will prevent the vacuum required to draw milk up the tube and alternatively any blockage of the milk channel will also obviously prevent the flow into the frothing mechanism.
Hope this helps.

SOURCE: Hi there, my Delonghi ESAM3500

If the temperature isn't high enough it's because the thermostat that regulates the heater from the tank is faulty. Unless you have experience in dismantling this type of units , locating and testing components, finding the correct replacement parts and installing them, there's nothing you can do. Take it to an authorised service center.

SOURCE: We understand that your problem

Based on the information provided above the machine is a bit old as 3 years of regular use is quite a while. If the frothing wand is the only part of the machine which leaks water it can be presumed that a replacement of the part is in order.
It will be advicable if you can afford a new machine to get a new one otherwise get an expert to replace the frothing wand and run a general service of the entire machine.
Water leakages around electrical appliances are very dangerous and the consequences are always disastrous. So ensure that either the device is handled by an expert or replace the unit completely.
Hope this solution has been helpful?

Coffee is dripping out of machine.

You have a pump issue. If it's new take it back and get another one. It's probably not worth trying to replace the pump on your own.

I'm getting the "generic alarm message even though I've cleaned my DeLonghi Magnifica. What do I need to do next?

Not good; from page 21 of the owner's manual: If the message is still displayed after cleaning, contact the service center.
The good news is that when I had to send in my ESAM3500 for warranty repair, I called DeLonghi (1-866-528-8323) and got through to their repair center without difficulty. They sent a new shipping box and wrapping material, and a prepaid shipping label to a repair center about 100 miles away. I got my repair ESAM back in just a week. I hope that your experience goes as well. If it's out of warranty, though, it could be expensive.

Make sure the milk lid is thoroughly clean and that hot running water flows through the openings freely. Make sure you're using 2% milk. Make sure it's cold 2% milk. If you're already done those things, it's probably a bad "coupler unit." That means sending your machine to a service center. In that event, I hope that your machine is still under warranty. This is what happened to my ESAM3500. The good news is that I got my machine back, with a new "coupler unit," in just one week, and now I am back to "like new" cappuccinos
