Washing machine (Hoover ws130) has developed a fault in that whenever
it tries to turn the motor, the motor runs at full speed. This means it
cannot wash and even on spin it spins for a few secs then stops. I have
seen the motor reverse. Reading around suggests that either the tacho
may be at fault or more likely that the triac has failed and is keeping
the motor at spin speed. Is there anyway of testing the triac to see if
this is the case. Or is it a case of trying a new one? I can source the
part (BTB08-600BW) and I get the impression that failing triacs are
common. Is this true? My concern is that if I call in the repairman he
will just recommend a new control board/timer which would be costly to
the degree that I would consider a new machine.

Thanks in advance for any advice.
