Washer Drier WD64 Wiring
The belt came off my WD64 and this took out the wiring around the mains filter that managed to wrap the Green/Brown wire off the mains filter around the pulley. The next bit is all my fault because I made an assumption and didn't look properly in poor light. The other end of the wire had been pulled off the mains push button switch and I had to remove the timer to find it, in doing so I assumed the plastic plugs connected to the timer will only fit in their respective places so I didn't notice that the top two blue plugs are interchangeable. One blue plug has all white wires to it and the other has all black wires. There was a big flash/bang when I turned on the machine as two tracks on the timer evaporated, fortunately I have another timer. Can anyone help?

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
WD64 wiring mix-up after belt damage caused timer short
- The problem
- On a WD64 washer drier, the drive belt came off and pulled wiring around the mains filter, including a green/brown wire that was wrapped around the pulley and pulled off the mains push-button switch. While refitting, two interchangeable blue timer plugs were reconnected by assumption in poor light. When the machine was switched on there was a flash/bang and two tracks on the timer were destroyed.
- Likely cause
- The strongest supported cause is that the two similar blue timer plugs were connected the wrong way round, causing a short circuit. The belt coming off and dragging the mains-filter wiring was the original damage.
- What fixed it
- The accepted advice was that, because the plugs were interchangeable and the guessed connection caused the short, they likely needed to be fitted the other way round. However, the discussion also warned that the flash may have damaged other components, so the exact full repair was not confirmed.
- Checks to try
- Visual damage to wiring around the mains filter
- Wire pulled off the mains push-button switch
- Two timer tracks evaporated after switch-on
- Consider possible damage to the pressure switch, door lock, front-panel switches, control module or PCB control panel
- Parts or tools mentioned
- Timer
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

These things are tricky. If there were two interchangeable plugs and you guessed but it blew up, is it safe to assume that they fit the other way? Unfortunately there's no way of knowing if the flash and short has damaged something else or not.

Thanks for the reply, that is exactly what I was about to do. As far as I can see the worst that can have happened is some welded contacts in the pressure switch and some switches on the front panel. My local Hotpoint parts supplier has a shelf full of bits for the WD62/64. If you see a pall of smoke over Liverpool you'll know I got it wrong :-)

Yes a big flash like that can wed contacts in the pressure switch or damage the door lock. The main worry is if it damages components in the control module or pcb control panel. Let us know how you get on.
