Hello everyone,
we are currently sitting in threes at our coffee machine and try to put them together correctly and somehow it doesn't work... 
Now from the beginning.
Our beloved coffee machine suddenly started to clean several times and to demand a decalcification. We did everything, but she stopped producing black gold. She was still cleaning, but somehow she didn't seem to pump any more water into the brewing unit, everything else (cleaning, steam, frothing milk and hot water) she did.
However, after a few decalcifications she didn't want to do it properly anymore and pump no more water through the pipes. They sponned then somehow more and more.
So my father took them with him, because the warranty has expired only half a year
, and examined them.
In the meantime we have inserted a new Kearimk valve driver and also exchanged the microswitches. But now we have the problem, after the assembly of the complete ceramic valve, that the machine always returns error 77. Sometimes it also works if we only lightly place the head with the hose connections on it. But as soon as it is screwed down (not vicelike) the error 77.
This can be due to the position of the driver, because the positions of the individual ceramic discs are determined by other parts... 
Can somebody help us if we are right with our guess? And does anyone know what the correct positioning of the individual parts is like?
We would be very grateful so that my husband and I can enjoy some nice and tasty coffee again.
