Hot Point Ultimate Wd860 Bang And Does Not Turn On
Machine was not on, we were watching to and there was an audible bang from kitchen and RCD was tripped. Thought it was the oven as that is basically what we were using at the time. Found out later the watching machine no longer turns on when button pressed. No lights, nothing. No problems and had been working well up till then.
Followed advice checked fuses and okay, tried another device in the power socked which worked.
Any suggestions? Would actually be interested to find out what caused it as machine was not on! Everything else is working fine and we have had no repeat event?

Hotpoint Ultimate WD860 bang, RCD trip and dead with no power
- The problem
- A Hotpoint Ultimate WD860 made an audible bang while plugged in but apparently not switched on, tripped the RCD, and afterwards would not power up at all. The plug fuse was checked and found okay, and the wall socket was confirmed working with another appliance.
- Likely cause
- The strongest supported diagnosis was a fault on the permanently live side of the machine before the main on/off controls, most likely the mains suppressor. The mains cable, terminal block and possibly the door interlock were also mentioned as possible fault areas. The exact failed component was not confirmed.
- What fixed it
- Recommended action was to inspect the mains cable and suppressor first for visible damage. If nothing obvious was found, the advice was that the fault could not be traced further without an engineer using an insulation test meter. No confirmed repair was posted.

Safety: Suppressors can retain charge after the appliance has been unplugged. Further diagnosis should be carried out by a suitably qualified appliance engineer.

It's very unusual if the washer wasn't even switched on at the time. When not switched on but plugged into the mains then electricity runs through the socket, mains cable, into the terminal block and through the suppressor so those are the things I'd check first - especially the suppressor (watch out though suppressors can hold a charge after being plugged in!).
If you can't see anything wrong with the mains cable or suppressor though you'll not be able to trace the fault without an engineer's insulation test meter to trace it as described here - appliance tripping electrics

Yes strange, thinking it might be the suppressor as this was listed on shorting link you provided. Some people seem to think it could be the door latch.
It's possible power may also go to the door interlock. But unless you can see something's blown it's not possible to troubleshoot without the insulation test meter.
