After reflowing everything on the controller board and reseating
the connectors it still won't work.

The motor of the washing machine spins for a few degrees and
stops. You can get it to spin (slowly) by pulling on the belt
but only in one direction ! Lots of sparks inside the motor.

The brushes are good and the motor seems mechanically fine.
I suspect the triac (ST BTB16 600CI). Plausible ?

Thanks in advance.

does the motor have a start capacitor and a centrifugal
speed switch to disconnect it?

I thought that was mutually exclusive with having brushes.

I didn't know washing machines had brushed motors?

They do have variable speed controllers that do fail, along with
shorting the motor windings with them!

See video showing washing machine brushes and how to replace them.

interesting, I don't work on such things but the few I have looked
at always had induction motors on them. I've never owned nor do I
even know any one that's ever had brushes replaced on their washing
machine..

Ours gets used almost every day and I replace them on the average
of every 5 years or so due to other problems, but never a motor..

In fact, I scabbed the motors from the last 2 I junked and both were
just AC induction. (squirrel cage types).

Lot's of sparks inside the motor doesn't sound like a bad triac to me.
Sounds like a bad motor.
