This machine when switched on and a program selected, start button pressed, the door locks, then pumps out for a few seconds, then all light go out and then the end light flashes 3 time then a pause the flashes again 3 times. Any clues on this one. Motor brushes checked, element and thermistor good readings, water valves serviceable. I suspect the control module but can anyone confirm this please?
Possibly heater failure, you need to check it with a megger for earth leakage.
E33 = Pressure switch fault, current leakage from heating element to
ground, PCB faulty, dust on tracks shorting is a classic cause of this.
