    This conderser dryer is blowing one shot stats for fun despite being clean as a whistle inside. Drain hole is clear, fans ok, no evidence of water on heater etc & float switch looks good.
    Does anyone know if timer should switch heater off when it reverses as I suspect this could be the problem ?
    Changed the cap by the way out of desperation made no difference 😡

    Thanks A1, I had kinda narrowed it down to that but it’s good to have confirmation 😉 , do you know if this is a fairly common problem on these ?

    Quite common on the PCB controlled machines, rare on the simple timer controlled ones in my experience though.

    agree its not as common on timer controlled. but does still happen from time to time.

    pcb ones are murder for it tho…

    It is simple enough to test for, I use one of those plug in monitors to see if the amps drop when the dryer does the short reverse tumble, observing the electricity meter is another way to check it.

    Its also an easy way to test if a dual/heat element model is working on both sides of the element. 😉

    erm, far be it from me to play devils advocate, but who says the heater shouldnt be on on reverse tumble?

    cos, according to the service manual –

    a2-a3 (b3 b5) is the heater switching ( off for the last few clicks)

    the only time the timer would be on is if it never switches the heater off

    unless im reading it wrong that is?
