ok, meter set to 2m ohms. 1 lead on the metal case then going through each connector at a time. the only ones which reads anything other than 1 (barring the one which connects to the case) are the brushes, they are reading .065 on one motor and .028 on the other one. Does this prove anything?

should also add, when testing. I didn’t put the motor back into the machine, just connected the wires. when the trip blew there was a viable flash from inside the motor.

Thanks again

Thanks for that.

ok – I have removed the carbon brushes on one of the motors, given it a good clean with a paint brush. Replaced the motor but still tripped.

I have managed to get the multimeter to the motors now, below are the readings. I think these are ok?

Motor 1
Brushes – 2.8
Casing 1.1, 2.2, 1.6
sensor 90

Motor 2
Brushes 2.8
casing 1.1, 2.3, 1.5
sensor 89.6

All wiring that I can see going to the motor appears to be ok. Im not sure what to check next?

Many Thanks

Hi Dave,

Thanks for the reply.

1. It was a used motor – but it must have been working to perform the first wash – right?

2. Not yet, I’m awaiting a multi meter – should be here tomorrow so will check both motors then.

3. Is this cleaning inside the motor? Whats the easiest way to do that? soft brush into the gaps?

4. Yes, I made sure I brought one with the same model number to the one I took out.

Many Thanks
