Miele G1143SC tripping RCBO

[jbjb]

Wondered why the cooker hood wasn’t working this evening… RCBO for kitchen ring circuit had tripped and culprit turned out to be Miele G1143SC dishwasher which I purchased in May 2009.

With the cabinet full of dirty water, I reset the programme by holding the START button and then started a fresh programme, knowing this should drain the cabinet first. Drain pump started OK and had all but emptied when the wash pump cut in (as it does at this point in the drain sequence, presumably to get as much water out as possible…) and the RCBO stepped in again. Don’t think it’s the heater as can’t see the need to heat water you’re pumping down the drain…

So I think it’s the wash pump, which seems to incoporate the heater and other horrors – Miele part 6770471. After 14.5 years I’m pretty tempted to ditch it, sadly. Weeks from new, I had to get Miele in because, if the door was opened mid-cycle, the wash pump then took 5-6 restart attempts to start running again, which seemed a bad thing. They replaced the pump but it’s been like it ever since and I’ve never had the same faith in it as in my trusty Miele washing machine.

From the experience of others here, if the wash pump has got damp, I’m presumably looking at seals, bearings etc.? How much of a nightmare is that going to be, assuming I can get hold of parts? (I’ve changed the dampers and brushes on the Miele washer this year, so willing to put some effort in if there’s a reasonable chance of success!) Thanks.

common fault on older Miele dishwasher is the pressure switch mounted on the pump motor. rubber diaphragm fails and water get into the switch electrics

take the base off find the switch and see if you can find dampness in the plug connectors

part no 6996821 £80 from Miele ( only buy part from Miele themselves)

“Don’t think it’s the heater as can’t see the need to heat water you’re pumping down the drain”… Very true but modern stuff does not work that way: you can have lives going to components but the neutrals are not in play = said component will not work BUT if that component has gone to earth fuse/trip pops off so it could be the heater. The leaking motor idea was a possibility too but then if that happened the basal float switches to emergency pump out rather than taking out a trip/fuse which you do not seem to have.
According to the Miele website the motor is £418.90 but not sure whether that is motor/heater as a complete unit – but not available online to buy apparently – typical Miele closed shop! !
I would have a good look and if you have a test meter you could check the heater to see if its gone to earth or just pull the heater wires off the heater (insulate their tags as necessary too) to test.
If it looks like you have to call Miele out to get the part (and if you can get the heater part only: the last Miele dishwasher I changed the heater the part was listed at 200 quid but wasn`t your model and that was some years ago now) as far as I know they now charge 150 quid for the first hour then 100 quid for next hour so you can ratchet up a horrendous repair bill very quickly so if either of those parts you might want to quit whilst you`re still ahead of the game now if you do not want to get in the throwing money at it loop i.e. what`ll be next?
After 14.5 years that isn`t all that great for a premium product, I`ve had even Indesit dishwashers last longer with minimal hassle but that was in the very distant past. I think you`ll find every brand of dishwasher these days will be challenged (that certainly includes Bosch / Siemens and Neff, Hotpoint, Indesit AEG, Zanussi) in some way or another so not sure where that is going to leave you; sans dishwasher perhaps? Too much money gone into gimmicks instead of the basic engineering but then I suppose it is gimmicks that flog machines (e.g. internet connected) and in reality it was forever the case!
