I can’t find carbon brushes in motor

[Seanog]

Hi, this washing machine is Crolls RT 9813. It’s maybe around 20 years old and it has been working erratically, and not spinning.

So I thought I’ll first check the carbon brushes, but after taking out the motor, I examined it closely and saw no sign of carbon brushes!

I tried to disassemble by taking out the 3 long studs that encase the motor, but even then I couldn’t take the casing off by hand.

its not a mchine we have ever had in the uk as far as i know but it may be an induction motor that does not use brushes

when you say working erratically can you be more specific

Ok, I ran a light wash and found the following:
The program finished, but the clothes came out wet. Also, after refitting the motor, there was noise from the drive belt every time it engaged the drum. but the noise became less annoying as the wash went on, becoming a fraction of a second noise.
At the end of the wash, the clothes were wet, but just to recheck I put some clothes back in and set the programme dial near the end where the final spin should start, and first some new water came into the machine, then the dial got stuck (as had happened many times before, but not in the previous wash). So I moved the dial on by the minimum, and the programme continued. Sounded like the water pump was emptying the water. Then the spin did come on and the cycle ended as normal, but the clothes still came out wet, maybe less wet than the first time. Not sure whether the dial got stuck before or after the emptying of the water.
Thanks

no spin can be caused by a drain problem or on an induction motor there will be a capacitor that when they fail over time gradually reduces the power of the motor. if it can turn light loads but stuggles with weight it may be the cap
as for the programme sticking it can be for 2 reasons, its either

1 waiting for something to happen heat, drain or fill etc
2 mechanical failure in the timer
