My Hotpoint washing machine WMA 32 kept tripping the circuit breaker on the fuse box. The motor would start but every time the heater element switched on the circuit breaker tripped the house. I found that both wires to the heater element had worn down to the bare copper, probably caused by rubbing against the lower concrete block (bad design Hotpoint). I repaired these with insulation tape. While doing this I also cleaned up the brushes on the motor - they were very 'sooty' but had plenty of wear left in them. I also found that one of the wires on the connector to the main motor had broken off completely, (before I touched anything - honestly!), either the 1st or 7th wire I think. This was reconnected but does anyone know what the wires are for i.e. would it reduce the motor speed by not selecting one othe windings. I had noticed that clothes were not as dry as they used to be, but had ignored this. So maybe this wire enabled the fast speed to be done.
The mashine now washes fine, but I'm curious about the wires on the connector to the motor.
Thanks for any help.

Please do not do another load of wash until this problem is fixed, or you may find yourself with a house/apartment fire!
I am thinking your motor (most likely) or the controls (least) have a short, and are causing your problem.
Take a really good look at the circuit breaker box inside, because a broken or loose ground wire ( there are two) can also cause this problem.
One ground wire should be white, one should be bare.
Each should be securely screwed into the lugs of the grounded section of the circuit breaker box.
God bless your efforts.
I hate to say this but a blown fuse in that machine wouldnt trip the breaker, so if you turn the breaker on and it stays on until you start the machine the motor is probably shorted and need to be replaced
hi martin it sound like bad earth this could be anythink check the plug for loose wire check the socket for loose wires if check motor wire in the washer also check circuit board connections if all wires are ok you could have a faulty motor hope it helps
run the machine, after it trips, unplug and carefully touch the motor,it may have a bad capacitor, or dry bearings causing it to draw excessive current,if these 2 things are not it, then look for a bare wire that may be touching case during this part of the cycle,and if you can get an "Amprobe" it reads current and check machines current draw during the start to trip current
First unplug your washer. Check the ground on the washer and make sure it isn't loose; this would be a good time to inspect the wiring harness for any problems. Next check the outlet (turn off the electric to that breaker first) make sure all the wires are tight and are making good contact; pay special attention to the neutral (white) wire. If that seems fine, and you are comfortable with going into you breaker panel, turn off that breaker and check the hot (the wire on the breaker) to make sure it isn't loose and then check the neutral wire. If either of these wires seem loose tighten them down....a loose wire will move when a load is put on it and cause the breaker to trip. If all seems normal and washer is still tripping the breaker you might want to replace the breaker.....they can go bad. Good luck!
it's possible that one of the carbon brushes have worn down to the bottom and it is sparking on the motor causing it to trip the fuse. It's just one possibility. Have you checked the carbon brushes are connected properly and that they have not 1) worn down and 2) that the wires are connected to them correctly.
It's unusual for a household RCD to go out on excess current from an appliance - the fuse in the plug top and circuit fuse/MCB in the consumer unit should provide closer protection. This leaves you with an earth fault.
Earth faults aren't usually related to motor load.
Watch carefully what phase of the cycle the trip happens. Does it correlate with the start of water heating? A very frequent cause of low current earth faults is water ingress into the heating element.
If you can trip the RCD reliably on every cycle, running the same cycle with the element disconnected would confirm whether or not this is the cause.
