    This washer worked fine today, however I had the idea it took a rather long
    dry spin cycle. During my second laundry load it took the water, but the
    machine failed to spin, it cycled the rinse periods Ok but it never turned
    the drum.
    Looks like the motor or its controls have died. There are too many wires
    running to the motor to allow me to troubleshoot. Anybody has a suggestion
    as how to diagnose ?, or could help me to a circuit diagram ?

    TIA

    Thus spake Bram Stolk:
    The timer on a typical washer has many switch contacts which it closes and
    opens in sequence. These timers are a high-failure item in most washers.

    Sounds like the timer isn't energizing a solenoid to engage the spin clutch.

    But you're right, you'll need a wiring diagram to see which timer terminal
    should be energized at that time, to confirm if the timer is failing.

    Good luck,

    Most appliances have a circuit daigram tucked away somewhere in the chassis,
    in a washer look inside the top control panel, usually folded up in a
    plastic pouch.

    Problem solved...Motor brushes ran out of useable length and failed to
    contact the collector....

    Commutator..

    Nice when it's a simple problem like that, too bad they don't have some
    sort of indicator when it's time to change the brushes, maybe a little
    mechanical flag that pops up on the back of the motor when the brushes
    run out of travel.
