Repair Guide 2-Another Repair: DeLonghi EN 95.P Coffee Maker leaks coffee into the container, problem: Semi-clogged nozzle.

ID: 206642

Description:

A repair I started at Repair Café Palma; the coffee maker was leaking coffee into the grounds container, only a trickle with hardly any pressure was falling into the cup, and the sound of the water pump seemed somewhat strained. A descaling with vinegar was performed, but it did not improve.
Video after descaling with vinegar: It appeared to be a water pump problem; since I had several spare ones from scrap units, I tried to give it a second chance at repair.

Before undertaking the teardown of the machine, let's start with the simplest step: checking for a potential clog in the nozzle or the sieve. To do this, remove the outer nozzle by prying it (at 9:00 and 3:00) using a thin-tipped knife; on this older machine, it was very simple and easy to remove.

Pry on both sides to remove the nozzle, as I indicated before; it is very simple on this 1st generation Nespresso coffee machine model.

This older nozzle does not have the internal sloped ramp that later models have (which tend to clog more easily), but just like the others, use and the passage of time eventually clog it with coffee residue.

Using a thin flashlight—I made one with an LED for these types of repairs—I check the nozzle for any potential clogs. It looks okay (aside from the light coming through the sides), but I proceed to disassemble the screen anyway.

For the teardown of the sieve, I couldn't use the PUSHER on this model that I already showed you in another document, since I made that one for a different Nespresso model and it is too short for this one.
(I will make a longer one).
Since there is enough space, I use a medium/small flat-head screwdriver, lean it, and give it a gentle tap with a hammer, which makes the round sieve pop out.

Check again with a flashlight and clean the front, ensuring there is no coffee residue left clogging it.

After washing the nozzle and the sieve under the tap with water, dish soap, and a toothbrush, they are ready to be put back in place. "Light" passes perfectly through them.

The screen in this machine is very easily repositioned; insert it from underneath and squeeze it with your fingers in a pinching motion, and it will click into place.

To insert the outer nozzle, first insert the lower part, which has a kind of flange; this must be inserted first.

With the bottom of the nozzle inserted, seat it into place and use your fingers like a pincer to fully hook and snap it in.

We tested the machine. In this case, it can be observed that the machine is no longer leaking brewed coffee from the inside. We will use a flashlight and paper napkins to check for any possible dripping.

Once the machine was checked, it still loses a few drops, but it no longer loses brewed coffee, so the problem was a clogged nozzle.
