Re: Indesit WG820 tripping out RCB
Thanks for all the help, but seems like the motor was totally ‘goosed’, so, following all the other little problems that we’d had, a new machine was bought.
I reckon that the motor had overheated from a previous incident and the coil insulation had burnt/melted on the armature, shorting the power to the chassis. Can’t do much about that.
More data into the well of experience…
Cheers,
Ian
Re: Indesit WG820 tripping out RCB
I would say you’re probably right! Got an occasional reading (as in dependent upon rotor position) of less than 50 ohms between brush and motor chassis. Fair to say that the coil insulation is breaking down? Or could it be (metallic) dirt build-up and clean-out-able?
Cheers,
Ian

Oops – misled myself again! Problem still persists…. Now looking for a rubbing wire. Anyone else any ideas/experience of this sort of thing, best place to look, etc?
Cheers,
Ian 🙁
Re: Indesit WG820 tripping out RCB
Ahhh…. I may have it! I mentioned the pump failure – well, at the same time (Law of Sod) a bit of dirt stuck the inlet valve slightly open, overfilling the drum, making it heavier than usual, causing the suspended part to move into contact with a rear strengthening bar, rubbing the main pulley wheel and sprinkling some tiny metal shards into the machine. Found one lying right next to, but not quite touching, the connector for the static coils. So, theory says a multi-meter wouldn’t see it, but 400 volts of mains probably would. A high voltage insulation tester would probably have found it, but I don’t have one handy 😉 . I’ll give the whole thing a good vacuum out, and re-assemble it tomorrow to see if that’s a fix, or I’ve just mis-led myself again 🙄
