Repairing Krups EA8800 bean to cup coffee machine episode 2

Here is a presentation of a second repair I did on my Krups EA8800 automatic coffee machine.
This time, my coffee machine gets stuck sometimes. The piston blocks in lower position. I have to say that my machine is now six years old and has more than 6000 coffees on the counter (thanks to telecommuting and Covid). The only solution is to turn off the coffee machine for fifteen minutes and then turn it back on.

I have to replace boiler / piston part.

Once again, I could easily order the parts from Midi Pièces Ménager for 100€ shipping included. The repair is expensive, but the coffee machine costed 800€ new…

Repairing a Lego Duplo train engine

This time, I will repair my daughter’s Lego Duplo train engine. It is from a Train Deluxe LegoDuplo 10508 set, but I found two issues.
First of all, the locomotive has to make “Tchou Tchou” sounds, but it remains silent. It is an advantage for my dad’s ears, but I like to fix everything.
Secondly, the locomotive is slipping and cannot climb the bridge hill properly.

Fixing an Airelec Indigo towel dryer

A fresh article with something new to troubleshoot. This time I will repair a tower rail that belongs to my father. It is an Airelec Indigo model, also sold under the Noirot brand.

This heater has two functions. A heating mode with a single heating element and a “forced operation” mode that allows you to quickly heat the bathroom before taking a shower. In the last mode, the heater enables a second heating element coupled with a fan.

This device works perfectly in simple heating mode, but when I enable the “forced operation” mode, the fan starts for a brief amount of time, then turns off, then turns on again for two seconds and so on. After several minutes of on-off cycles, the fan works continuously. At first glance, it looks like a power supply or a chip reset issue.

Repairing bean to cup Krups EA8800 coffee machine

Today is a sad day, my coffee machine is broken ! No more engineer fuel 😢 After multiple tests, it looks like the coffee grinder is worn out. Coffee powder is accumulating and it blocks the grinder. My coffee machine is making a troubling noise but it does not make any more coffee.

First good news is that Krups brand is distributing spare parts. You can find them easily on the internet. I finally ordered a new coffee grinder on Midi Pièces Ménager website for 75€ including shipping costs. Cost is quite high but it is less than 10% of the cost of the machine.

Here I will detail how I teared down the coffee machine and how I fixed coffee grinder issues. It can be useful if you have the same type of machine.

Blog opening

Hi everyone,

I work to redesign my personal website, which was close to clinical death.
I will try to add more content by opening a blog section.

Docs

Docs section contains document I use for my daily electronics hardware engineer job.
It will be exclusively in english, because it is the hardware engineering language.
I use theses documents for my work to do computation or to share data with partners.

Blog

I will bring to life an old fashionned personnal blog.
My goal is to write articles about technical topics, like machine repairing or interresting stuff I find when I browse the web.
This part will be translated in french and in english, because there is few technical french content available on the Internet.

I wish you a nice tour on my website !

Nicolas
