Hotpoint Aquarius TCM580 (UK) Tumble Dryer Drum not Spinning

Hello.

I have a Hotpoint Aquarius TCM580 (UK) tumble dryer, purchased in 2017.

The drum stopping spinning during a cycle today.

* The unit has power (the water pump is sounding) so no blown fuse.

* I’ve taken off the pulley wheel and cleaned it. No change. It’s in good condition.

* The drive belt is in good condition and I can turn the drum by hand. This in turn spins the pulley wheel and motor.

* I don’t think it’s the capacitor. If I turn the dryer on and try to spin the drum by hand to get it going then it still doesn’t go.

* I would guess it’s then the motor. It is getting very hot. However, if I remove the pulley wheel and belt, it spins. The electronics are working as there are brief pauses in the motor cycle. Maybe the motor can no longer cope with driving the drum(?)

* I’ve tested the motor with my multimeter: it has continuity from neutral to the two other terminals.

Any ideas?

Thanks.

Oliver.
