Trying to get my X90 to work properly. I got it in broken state, and i've done a complete "service" on it, lubricating all O-rings, connections etc. Descaled the frother nozzle, cleaned the Solenoid for frothing etc. The machine has no error codes and brews Coffee, but not stable. If it's the first cup of Coffee you make on it since a while, almost nothing goes into the cup - It only goes half way into the brew and then spits it out in the waste container. If you immediately brew another cut afterwards, the content goes into the cup. It seems impossible to use ground Coffee on the machine, i place a spoonful in the funnell and it only goes some part of the brewing process and stops. I cannot see any leaks, it's just like it starts brewing and then stops for some reason. I cannot seem to find any pressure transducer/regulator on this unit - And idea of what could be wrong ? TIA!
