As allready mentioned, i cleaned the spindel, brewery unit etc. and lubed everything. In addition I exchanged the two O rings at the brewing unit and the one on the postion. Since than it happens only once a week instead of evrey second coffee
Update: i the last couple if weeks it got so frequent, i needed to replace the hole mashine after 5 years on duty. I took the same model and got directly disapointed by the removed main switch in the back. It also seams to be noise in a more anoying way. But still the coffee is tasty 😋
I found the solution! The belt on the transmision is too loose. You have to move the motor a bit . The belt must be tight on the weels.😉 Or simple replace the belt! That's it.
Consegui solucionar este problema É necessário fazer a limpeza na máquina, principalmente no ferro que corre o infusor de cima para baixo - limpeza infusor - limpeza parafuso que sobe o infusor
Takže mam rovnaký problém sú tam tri microspinace u mňa bol problém ten jeden ktorý sa nachádza hore za hlavným panelom premeral som ho a zistil som ze on je stále spojený a matrika ho ma rozpojit a to nerobilo tak som to vybral prečistil a zložil nazad, kávovar už ide ..zatiaľ možno to robila aj vola na matraci keď ze som ho rozobral celý
At the moment i looks like greasing (lubrication) of the spindel is the key. I've done it to a point were you feel it's too much, but since than it's close to solved
