Krups EA8908 - message "Disconnect and reconnect or use application"

Today, between making one coffee and another, the message "Unplug and reconnect or use the app" appeared on the display. Couldn't turn it off or turn it off. After disconnecting the plug from the socket and reconnecting and switching on the coffee machine, you can set the date and time. Then it says "Preheat" (even though I don't select any coffee to prepare) and after 1-2 seconds it says "Unplug and reconnect or use app". The appearance of both messages is accompanied by sounds (as if something is switching). Maybe someone had the same problem?

I have but it happened to me today Do you know what was the reason and how to solve it???

I had a boiler to replace. However, this message can mean many different faults.

You can probably hear the relay ticking.
So the problem is with heating or temperature reading.

Hello, I join the topic, yesterday ok today problem and it shows "Automatic maintenance" two cycles at the end of "Unplug and reconnect Or use app". The espresso machine is over 2 years old. Is there anything I can do on my own or is it a service? Thank you.

Two cycles of what...? Filling the circuit with a nozzle, or two cycles of boiler operation, i.e. the descent of the pressing piston down?

After switching on the coffee machine, "Automatic maintenance" is activated immediately, you can hear something starting and then it is filled with water, "Set the 600 ml vessel under the nozzles", OK, Filling the machine, Then again the same thing and the message "Disconnect and reconnect or use the app.

No water flow reading.
For verification - flowmeter, flowmeter harness, board module - in that order.
The flow meter is just a standard hall sensor.

Thank you for your help.

Hello, I have the same problem, unfortunately replacing the flow meter with the harness for a new original one did not give anything

In my case, the espresso machine landed in the service, the calcified water system was cleaned and it helped. For cleaning, use ready-made descaling liquids for coffee machines, not powders and tablets.

I have the same problem - Automatic Maintenance turns on, a 600ml vessel under the nozzles, OK, some water will flow and this error pops up. Once it helped to disconnect the equipment from the socket for a few days.
Have any of you tried to do "cleaning the calcified water system" on your own?


Earlier there was a problem with the grinder replaced by the factory service in Wrocław for a fee - allegedly flooded. Overall, I think this model is very poor quality.

Unscrew the front and top panels and look inside to see what the brewing unit looks like. Maybe the culprit is not scale, but coffee or coffee grounds have blocked the plunger.

I immediately after turning on the coffee machine, as soon as any information appeared, probably automatic maintenance and the settings button lit up, I held it down and held it until the coffee machine turned on. There was a process of maintenance, rinsing on the way and it worked. At the moment, I'm doing cleaning because I've had such a message for two weeks, but he left the cleaning process to return after vacation

Probably this problem is no longer valid, but I just fixed my coffee maker that had exactly the same symptoms.
I am sharing the solution here, maybe it will be useful for other people having the same problem.
The reason turned out to be a broken tip of the temperature sensor, which is permanently attached to the boiler casing.
After sticking with conductive glue, the error disappeared and the espresso machine works without errors.
By the way, it was cleaned of all the ground coffee dirt inside :)

This may be the most common cause of this error: a clogged water filter - not in the water tank, but in the espresso machine. It's the white part on the back of the case where the water drain from the water tank goes. To clean it, you need to unscrew the espresso machine (the guide is here:
https://youtu.be/S0cUNKSh8DY ), remove the water filter (located on the flow meter), clean it thoroughly and reinstall it.

This reason is also described here:
https://www.bean2cup.org/forums/index.php?s=2...73a9b5bb5b199b3eacae316&showtopic=18644&st=15

It turns out that it is not even necessary to unscrew the espresso machine - just first remove the black gasket that protects the filter, and then remove the filter itself (it's hard to do, it's best to have some pliers handy). You also need to be careful when installing the filter so as not to block the side water outflow (there are four meshes on the side of the filter, you have to insert it in such a way that the water flow to the side outflow is ensured).

Hello, when heating milk, this error pops up disconnect and re-use or use the application.

This error usually and most often causes unglued cables or a cable from the ntc sensor of the boiler, anyone who starts messing with the coffee machine can move the sensor or the cables will connect or not, the first answer is replacing the boiler ok will help because the sensor is glued to the boiler but it can either be soldered to boiler or stick it on thermally conductive glue and the error disappears. No filters, no descaling...

And what to do in such a situation?

Disconnect and re-use or use the application" and errors 09, error 10 if you have such errors, please contact net.mar(_at_)interia.pl

For me, the reason turned out to be a broken tip of the temperature sensor, which is permanently attached to the boiler housing.
After soldering, the error disappeared and the machine works without errors.

Thanks for the hint.

Hello, I will refresh the topic a bit, of course the same thing happened to me, the message "disconnect and ....." after following the recommendation disappeared, but instead "install 2 tanks" or something similar appeared, generally the message appears when the container is removed for coffee grounds. The container is always in its place 🤣. I disassembled it, checked the micro switch - it works, but both G4A00 216 ºC thermal fuses blew (the failure generally occurred after brewing coffee and in the milk frothing mode - which did not occur).
I want to know the reason, because the fuse doesn`t blow like that. Does anyone know the resistance values of the heater in the furnace and the temperature sensor mounted on the furnace (which is often mentioned here)?
Or maybe some other ideas as to why this happened.
Thank you in advance for any help.

It looks like the electronics are broken. When the boiler or NTC is damaged, it generates completely different messages. It simply displays the inscription "Heating". If you disconnect the boiler plugs and NTC, will anything change? Probably nothing that will indicate that the system is not progressing to this phase of testing.

For me, the message disappeared after removing the water tank. I poured it out, rinsed it, put it back in and it still works.
Before disassembling, I suggest you do this simple step (press all drawers, wash) - if that doesn`t work, then disassemble.

Hello,
Today I had the same symptoms, it turned out to be broken cables from the temperature sensor.

I know the topic is old, but maybe someone else will have this problem.
In my case the thermal fuses on the boiler were blown. The ones next to the ntc sensor. Visible in the picture in this topic above.
The sensor connectors looked ok. but when pulled harder one fell off and this was probably the cause of the burnt out thermals.
The espresso machine may display, in addition to the standard "disconnect connect or application" message, a message about the need to lining up the tanks, because the limit switch and one of the thermals are on the same wire.
Tomorrow when the parts arrive, I'll put it together and let you know if it works.

Edit: I forgot to write. Everything is working. The machine makes coffee like new.

Where did you order the parts?

>>21309731 .
On Allegro. The name of the auction below. I think you can also match it somewhere else after the parameters from the auction. In any case, I bought exactly that and it works until now.

After a few times of following the commands from the display the coffee machine worked. 🙄 On / off fills the coffee machine etc. And so far it is ok.
