Hello expert,
I note the following:
When the piston is in the lower position (presses), it is slightly pushed up by the water pressure. A mean crackling sounds from the back of the machine. When the cover is finished, the piston goes down a bit and then goes up again. It cracks again very loudly and as it seems in the same position as the previous cracking.
Does anyone have any idea what that could be?
Greeting
Florian
