Hi on the 40 degree wash it starts off at about 3 hours then cuts the time dowb to about 1 hr 40, then it puts the time back to 3 hours then unlocks the door. I fitted a new PCB and it did the same changed the heater and NTC but its still the same,
What’s the insulation reading like and did you use a genuine heater the short type. They are having issues with the heaters that cause random faults there are 3 different elements listed on connect and they are the long type kai
Put the machine through a self test mode to see if there are any errors hold the top left option button in and turn main dial 2 clicks to the right until all leds are light hold for a few seconds release and press all option buttons then the start button . Is this fault only happening on 1 programme? If so either door lock or motor would be the next to check kai
