Re: Bosch 1200 Classixx Express door sometimes won’t open
well 2 poss probs spring to mind
1 heater if there is a slight earth fault on the heater it upsets the electronics and wont finish the prog. try disconnecting and insulating the wires to the heater and run a rinse prog
2 the pressure bell blocked. the water height is decided by an air pressure switch if this is sticking or the tubes are blocke it will think there is still some water in the machine
(be careful if its a late machine you can destroy the switch by blowing in it)
