    I have a Bosch WFB1605 with ineffective speed control. The drum runs at full speed in alternate directions during the wash part of the cycle.

    I haven’t yet investigated the problem further.

    What should I be looking for to fix the problem?

    Hi
    Its either the tacho on the motor or the speed control module itself at fault.
    May I suggest an engineer from the link below.

    Just to add, you could have earth leakage from a component aswell causing fault.

    Thanks.

    I’ll try to check the tacho output when I get chance to get the thing apart; what voltage should I expect at full speed?

    How feasible is it to replace the speed module or tacho?

    I checked the tacho and I think it’s probably OK; I can get about 3V a.c. when spinning the drum by hand.

    Assuming the fault is with the speed control module where can I get one? It’s a COPRECI BYR891-3

    Thanks in advance.
