WM52 motor
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

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hotpoint First Edition 1000 WM52 motor connector pinout query after motor bearing seizure
- The problem
- A Hotpoint First Edition 1000 WM52 washing machine stopped working and the motor would not turn. The owner found the bearing at the brush/commutator end had failed, dismantled the motor, and then needed the correct wiring positions for the 8-way motor connector after not recording the original pinout.
- Likely cause
- Confirmed fault was a seized or failed motor bearing at the brush end. The forum also indicated the connector positions were needed to reconnect the motor correctly, but the exact WM52 pinout was not fully confirmed from the discussion.
- What fixed it
- The accepted reply advised that two wires are for the armature/carbon brushes, two or three for the field coil, and two for the tacho coil. A Hotpoint Aquarius WF-series diagram was offered only as a possible comparison, not a guaranteed WM52 match: pins 1-2 tacho, pins 3-7 tapped field, pins 3-4 full field, and pins 5-6 armature. A later post added that the commutator-end bearing can be replaced and identified a replacement bearing as 6001 zz/c3, but no completed repair on the WM52 was confirmed.
- Checks to try
- Motor found not turning
- Bearing failure identified at the brush/commutator end
- Connector observed as 8 positions in a single line
- Owner believed pins 1 and 2 were for the tacho
- Pins 7 and 8 reported as unused on the owner's connector
- Parts or tools mentioned
- Motor bearing 6001 zz/c3 (28mm x 12mm x 8mm)
- Small 2-arm puller
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

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)
Nice one cheers
