Krups EA80*

Hello
,is there a button combination to
reset
the fully automatic coffee maker to factory settings
? Problem
:The red slider for the coffee grounds could not be pulled out. After I opened the machine, I noticed that the "impression cylinder"(?) did not move all the way down to trigger this "plob". I took everything apart, cleaned it and put it back together again properly. Cable connectors and sensors checked. After switching on
, all 4 lamps
now flash
.

What could be the

mistake?

I'd be very grateful for your help!!! LG

Got the exact same problem. The display shows 9 as the error. All cable connections have been checked again and the connections on the brewing unit are also fixed. Flowmeter works and hoses have been cleaned.
