    I have a Bosch Classixx 1200 express washing machine (WAE24162GB/03) which will not go into the spin cycle. During the washing cycle it doesn’t agitate but does a very short spin rotation (reasonably fast but only one quick burst). Although the motor seems to function okay, I’ve changed the motor brushes, which were quite worn. It seems to drain okay but I have also cleaned out the pump, the waste pipe (the latter was full of sludge) and various other pipes/tubes including the pipe from the pressure switch. But it’s still not working and my next thought is to replace the PCB, although I’m getting nervous that I don’t really know what I’m doing and I could just be wasting time & money. Can anyone offer advice?

    Hi my names is Nick I run an appliance repair business in Northampton,

    Unfortunately the problem you’re describing here could be either the main board or the motor. Do you have a multimeter to test across the motor connections?

    You should find that the two motor tags with the lowest resistance complete the armature circuit through the carbon brushes, maybe around 1-4 Ohms.
    Two or three of the others will all have continuity together at slightly higher Ohms, and these are the field winding, this has more than two connections for speed control.
    And the last two will have the highest resistance and is the taco (speed sensor) something over 10 Ohms possibly up to 30 or more.
    If the taco is open circuit, i.e. unlimited resistance then it is time for a new motor as Bosch motors have this built into them, also check if the wires run from the block to the taco correctly and give it a tap to check for a broken magnet!

    If this all checks out then look for a short circuit in the wiring up to the board.

    If it still checks out ok then yeah sounds like the board, could be a bit costly, good luck,
    I hope I’ve helped.

    Thanks Nick, unfortunately I don’t have a multimeter but I may be able to borrow one? However, I must confess that, having never used one, I’m a bit daunted by your description of what to test! It may be time to call a qualified engineer? Thanks anyway for your prompt response.

    Regards
    Steve
