Ea8150 problem machine and various errors

Hello everyone, maybe someone can help me because slowly I do not know more.

I am a hobby screwdriver and actually repair everything and now I have a 8150, which leads me to despair.

It started with a stuck in the cleaning program which was quickly done by pressing the steam button.During cleaning, he let the water into the lower drip tray.

Have cleaned the screens of the pistons and the drainage valve cleaned and greased.

After that I rinsed the machine and made coffee.after about 10 cups the pomace container symbol blinked.

The microswitches of the pomace container and cleaning slide work (cable to plug measured and switch as well).

Then I noticed that the pressure cylinder is much too low and has missed the underlying microswitch.

I disassembled the cylinder completely and found nothing except for a slightly rusted spring.

In another forum there is also a thread on the subject
https://komtra.de/forum/index.php/Thread/8704-Krups-EA8108-Kaffesatzbeh%C3%A4lter-leeren-und-CLEAN-blinken/

So I have test glued the missing piece to the nose but still the indicator of the Tresterbehälter still flashes.

Then a direct check of the components was done.
-Pump, grinder and motor, gear unit for the water system work - brewing unit
heats and microswitch were all measured through - all
cables to plug of the power unit measured for continuity - NTC
and thermocouple of brewing unit was removed, which was confirmed with a plug symbol so everything is OK


.




Now I have bridged the state of the machine that it should actually start but the pomace container symbol flashes unfortunately still.

Either the machine still has a low water protection or I'm missing something?

Have meanwhile all possible start conditions of the microswitch through and still the icon does not disappear.

A way to the factory settings I have unfortunately not found and a reset option lt.Krups also not.

I think that the machine is no longer to bring to life, yet it worries me not to know what it is.


Maybe someone has an ideaGrussRalle

Unfortunately, I do not get on with the machine and will see if one does not get an identical construction to reproduce the error.

Therefore, I have disassembled the machine and stored the components.

This has been done for the time being.

So the pulp symbol appears after 9 cups. That's also what it says in the user manual. Normally once out with the container and back in, should solve the problem, because the microswitch is triggered. Suspect times that the display still does not go out?

It seems to be more of a board problem because there is no other way to explain it.

Hello Ralle, unfortunately can not contribute to this problem but maybe you can help me.
At my EA815 appears about 10 sec. after switching on a flashing plug symbol and nothing works. I checked the contacts on the NTC. Both soldered. has brought nothing. Could the NTC be defective? How can I check it or replace it. Or can it be bridged.
Thanks for hopefully successful advice.

hey creations,

well the plug symbol comes as far as I know with an electrical problem. You have the 8150 2 versions of the machine.In the version before 2018 are 2 NTC s installed.One at the pump and one at the boiler as you have already noticed like abrissst.You can both with a multimeter ohmic durchmessen.
At the pump is a very low ohmic value.At the water heater it was I think 120 KOhm.
If the value of the heater does not fit, you get the plug symbol.

My answer was not quite correct.

The brewing unit is directly connected and must therefore have a measurable resistance of 120kOhm at the white plug.

If it has not after soldering, measure again at the contact plates, otherwise the internal heating coil is defective.
