Krups EA8050 - the plug symbol on the display after setting the hour

Question

Hello.... I have a problem with the Krups EA8050 coffee machine, namely after switching on and setting the date and time, after a while the drawing of the plug with two oppositely directed arrows appears on the display and nothing else happens, please advise.
Attached is a photo of what appears on the screen

nioop · Answer

Please check the NTC sensor and thermal fuses on the heater.

victor_pe2 · Answer

I checked the NTC sensor and thermal fuses, they are operational Still does not perform a self-test, only what appears in the picture

nioop · Answer

And so.. After turning on, setting the hour before the plug, does anything start in the espresso machine? Pump checked?

victor_pe2 · Answer

after setting the time, the self-test is turned on for a moment and what is shown in the photo pops up. I tested the pump briefly and it works

MARCIN.SLASK · Answer

The symbol would indicate to remove and insert the power plug.
Try to hold down the 3rd key (pair) from the left with the plug removed and turn on the plug. When the question is displayed, release the key and confirm. remove the plug and restart the machine after a while.

victor_pe2 · Answer

I did as you wrote and the message Remise en sta de vente terminee appeared Added after 7 [minutes]: I took a photo

MARCIN.SLASK · Answer

And?

victor_pe2 · Answer

Still the problem is not solved, I expect advice .... best regards

MARCIN.SLASK · Answer

Where is the photo you wrote about? You gave YES and approved? Did you restart and what was the reaction of the machine?

victor_pe2 · Answer

After following your instructions, the inscription as in the photo appeared

MARCIN.SLASK · Answer

Do the same thing again but pull out the water tank, drawer and coffee grounds container. It should appear:

victor_pe2 · Answer

I did that, but still the same Added after 5 [minutes]: So a screen like yours appeared, I approved and no changes

MARCIN.SLASK · Answer

You committed, rebooted and what was it?

victor_pe2 · Answer

auto-maintenance turned on for a while and again the screen from the first photo, i.e. the plug

MARCIN.SLASK · Answer

And the basic settings of the device (language, date, time ....) should be included. Maybe there is another software. I can't help much more - maybe something is blocked.

nioop · Answer

But it is the pump that starts during the self-test? The piston goes down during the auto test?

victor_pe2 · Answer

Yes, I skipped these settings, but it was true, I set it as you write and after finishing, the self-test and plugin turned on

victor_pe2 · Answer

I managed to locate the cause of this message, namely the NTC temperature sensor was damaged, which I replaced with a 100 kΩ thermistor and everything works now.

Tomek79 · Answer

Do you happen to have photos of what it looks like after the replacement? Did you glue directly to the boiler or to the ceramic tile?

service_contact · Answer

I repeat the question and request to send a photo if possible. I have the same problem.

Tomek79 · Answer

I mastered it. I don't have a photo, but I scratched an old smd thermistor and soldered a 100kohm glass one so that the side touches the ceramic plate. greetings

Hello. I have a similar problem with the plug. I dismantled the type and what turned out the thermistor evaporated. I also had a pill thermistor but it has 86 KOhm and soldered it, assembled it, did a self test but the water was cold. I checked the boiler works and now what. Is 86K not enough or something on the module?
