Re: Hotpoint WMA63 tripping RCD on fast spin
Hello, All the parts arrived in the week, so I set about working on the machine today. Unfortunately I have the wrong harness. I ordered the 10-way harness but it seems the cable from the motor goes to a circuit board on the bottom right hand side (as you look into the machine). There is a 7-way socket one each end of this cable, so I guess it’s called a 7-way harness. I saw one of these listed on the hotpoint web site. I did double check the part I needed with hotpoint, so it’s disappointing they didn’t spot this.
The motor was a bit stiff, perhaps it had not been removed before? I checked the brushes. How long are they when new? There is 2-3cm there, so nothing to worry about just yet.
Re: Hotpoint WMA63 tripping RCD on fast spin
It appears I may have given you the wrong part number for the harness, the parts diagrams are not very clear on harness info. 😳
I have been over them again together with a wiring diagram and these are the numbers I have come up with.
7 cable harness from motor to chopper board is C00201717.
5 way harness from main power board down to chopper board is C00201718.
It actually shows that one coming off the bottom of the power PCB when it fact it plugs into a socket on the surface of the board, as its the only 5 way harness I’m assuming that is the correct one.
The motors are quite tight and do need tapping or prising out of the drum mountings, if you have taken it off then at that age you might as well stick some new brushes in anyway.

Don’t worry, Hotpoint told me it was that part too and they are going to exchange it for the right one.

I did wonder about changing them after going to all the effort of removing them but I figrued, I may as well wait until they were worn more. Are there any signs I should look for nearer the time, to tell me they are due to be changed, or is it too late by the time it starts showing? Thanks.
Re: Hotpoint WMA63 tripping RCD on fast spin
The DC chopper board is there to allow the machine to achieve a 1600 rpm spin speed.
As regards the brushes it would do no harm to have a look, however I have just done a main bearing change on a WMA63 this afternoon.
It is about 9 years old and although not used for a large family it has had decent use, the brushes were less than 1/4 worn.
The FHP motors used on these are quite decent tackle.
You will get very little warning when the brushes give out, possibly a slightly harsh, crackly noise on final spin.
