    Hi,
    Got a mystery fault with this one. No wash or spin. Have circuit tested around motor and visual brush check ok (brushes replaced approx 6 months). Module to motor loom checked ok. Have replaced triac on module. By turning the drum pulley the motor kicks in on both the wash and the spin with no brush sparking problems. Motor then mysteriously worked fine without any prompting, so told customer to keep check and report if fault re-occured. It completed 5 washes ok and now fault has returned. It seems to me it maybe the tacho coil (reading was 17 ohms) but have no manuals to check from. Any clues please?

    Dry joint on motor module?
    Don’t have tacho readings sorry.

    Thanks Greg. Couldn’t see anything obvious on module but will double check.
