WM52 motor

[rcpilot]

Basically I have a Hotpoint First Edition 1000 model num WM52, it's like Triggers brush off only fools and horses, over the years I have collected many spare parts from other peoples washer of the same model and have repaired it with such. It gave up the ghost the other day and when I inspected it I found the motor would not turn, on further inspection it was the bearing in the brush end, as the spare motors that I had did not have the same connector on them I decided to dismantle the motor, but silly me I did not make a note of the pin outs in the connection socket. the pins in the connector are all in a line and NOT one set on top of the other, Looking from the pin side it has 8 places where the spades can be placed in the connector I numbered them 1 - 8 starting from the left, however I tried the plug in the socket and found that numbers 7 and 8 are not used and I can remember that numbers 1 and 2 are for the tacho so what are 3,4,5 and 6 for. I have been on all sorts of websites but cannot find out the exact wiring diagram for this motor.

        All help gratefully appreciated   Ken

Two wires should be for the armature which go to the carbon brushes and two or three go to the field coil with two going to tacho coil with a very high resistance. I don't have many circuit diagrams left but I just found one for Hotpoint Aquarius washing machines WF.. models made in 2004 which "could" be the same but I can NOT guarantee that.

It says pins 1-2 Tacho. Pins 3-7 tapped field

Pins 3-4 Full Field

Pins 5-6 Armature

So that one sounds like pins 5 and 6 not used though you think yours is pins 7 and 8 not used so it could be different.

Hi Guys! I've just bought a nos GEC motor for my WM51 w/m, and it came with a pinout sheet for the  various plugs used on these motors, I know its probably too late for the OP, but I'll post a pic of it on here for future reference.  btw, the motor was an older model, with a different design tacho, but I'm swapping over the armatures as it's the usual bearing issue. btw(2), the bearing on the commutator end is easy to change with a small 2-arm puller... the one I've got is for removing wiper arms and battery terminals, and works a treat! A replacement bearing is type 6001 zz/c3,  28mm x 12mm x 8mm.           I'll post the pic of the connector sheet tomorrow (it's late and it's in the shed)
