Bosch WFL2480AU/04 Front-Loader Washing Machine

 

Motor only does 1/2 turns at the start of any cycle and then stops!

An old one (bought new 2000) but a good one!  Changed brushes twice since 2000 - that's it until now!  Used once daily for 20 years.

Machine was noisy (like bearings on the way out) when on spin.  Checked the tub - all good, no play whatsoever.  Before I got the chance to check the motor it was washing a load and then the motor seized up - couldn't turn!

 

Found small pieces of metal under the motor when I removed it and the motor shaft was seized up.  Took the motor to a bearing shop and they removed and replaced the front and rear motor bearings - the rear one was shot.  Put motor (with new bearings fitted) back in to the machine (brushes still about 1.5cm long).

So, water fills, water drain pump works - front panel (PCB) seems fine - solenoids click and lights go on/off as expected.  As soon as cycle starts (wash or spin) the motor starts, drum turns and then it stops.

I'm stumped as to what it could be?  Could something else have gone wrong when the motor seized for a minute or so?

I checked the thermal cut-out switch (Klaxon?) in the motor with my DMM and there is continuity - seems to be fine.

 

Is it likely to be motor (brushes, commutator, tacho, windings), PCB front panel, suppression capacitor (reduces interference)???  The suppression capacitor looks fine, and there is nothing obviously wrong from a visual perspective with wiring or components that I can see.  The motor is 6 pin.

Any thoughts?  Thought of just buying a cheap replacement second-hand motor and seeing how that goes?
