Dishwasher Trips during cycle

[mattchappers]

I have a Proline dishwasher about 3 years old.
Last night it tripped my house electrics completely (RCD)

Today I connected it to a separate RCD to save the rest of the house and tested it again. Same thing, same place in the cycle.

It's in the part marked rinse somewhere in the rinse / drying stage.
If I skip a bit of the cycle then restart it it completes fine. No water left.

Seems to be a recurring issue with that bit of the cycle.

It's a pretty simple dishwasher so I don't think it has a separate heater for drying though I could be wrong.
Quick look underneath doesn't show any obvious signs of leakage though it's pretty well boxed in so I haven't got as far as the guts of it yet.

Any suggestions? thanks

I suspect you have an intermittent earth fault on the heater element. It seems somewhat strange that it only appears to trip on a drying cycle but there you go...not everything is always A4. You could try leaning the machine forward (or backward for that matter) & see if water runs off the bottom plate. In which case that would indicate a leakage someplace. You could be unlucky & water is leaking onto one of the other component, this could also trip your RCD. But my money is on the heater. Unfortunately Proline is just a badged make marketed by Comet, your machine is likely to be produced in China (Oh woe is thee!). Spare parts are not easy to to track down & service information is virtually impossible to find. You really need someone equipped with a 500v megger to verify the heater is defective, alternatively you could just take pot luck & try to source one yourself. The only places I can think of that may supply parts for these inferior machines are: http://www.espares.co.uk/models/dishwashers/proline/p/1083/1169 or http://shop.ukwhitegoods.co.uk/Dishwasher+Parts/Proline.htm
Good luck
