‘:?’ More erratic machine behaviour… Came home to find my wife had loaded and put the machine on and I watched it run right to the end of the cycle no problems – dishes clean, dried, machine fully drained… reloaded with more dishes and started again. Ran for 3 minutes then jumped to “0 mins” opened and started again programme began at “85 mins” ran for 1 minute then blank display no indicators… another door open and restart “34 mins”… next jumped to “0 mins” but machine kept running but time left not changing…
1/ Heater faults throw the computer, especially earth leaks.
2/ Sludging issues cause the machine to under-fill, which can cause the heater not to work correctly, which will throw the computer.
3/ The computer boards do just fail, simple fact.
Time to get the covers off and get the test meter out. Stay safe, power off first.
Firstly
Before I take the sides off is there anything to investigate in the door… I mentioned a kind of solenoid clicking noise (in my original post) which can be heard when the machine won’t start or if it has jumped to “0” then on/off is pressed to cause a restart… typically 2 or 3 clicks can be heard then we either have lift off or the machine display blacks out….
Secondly
I picked up from another post that holding program buttons 2 and 4 (left to right) causes the machine to drain. this has been useful particularly when it has stopped mid cycle… are the any other magic combinations that would help in testing/diagnosis… a Bosch machine
