Hotpoint Aquirius 1100 Washer tripping RCD, motor ?????

[ImSpartacas]

My hotpoint 1100 washer dryer is tripping the rcd, the insulation resistance when meggered is pretty low, less than 1 megaohm.

If i disconnect the bushes its ok, and does not trip, also if i disconnect the block connector at the end of the motor the insulation is ok, its also ok if the bushes are disconnected.

I tried cleaning the bushes and stator, blowing out the carbon deposites with compressed air, but still trips.

IS IT THE MOTOR ?

I susspect it is, if so, where can i get one for a raesonable price ????

Cheers,

Dennis

PS, my wifes worn underwear is starting to build up, i may sell on ebay to fund the motor !!!!!

Thanks
But is it the motor ????

the bushes look fine

i would say i have resistance from the armature windings back to earth of the motor

cheers

If you look carefully at the insulation material at the end of your commutator you may well find it is cracked. Carbon dust can lodge in such a crack, forming an earth leakage path. Alternatively, you may have shorted turns in the armature due to overheating and melting of the insulation lacquer. This causes sparking at the motor brushes which can also trip the RCD.
