Indesit D63 tripping RCD

[PeteW]

The dishwasher trips out the main RCD at the fuseboard when it gets to the point when the water is hot i.e. producing steam. If I leave the machine for a couple of hours it then goes on and completes the cycle. I have done an insulation resistance test, but all seems OK. I assume that the steam is getting into the electrics somewhere, but cannot work out where.Has anyone else come across this problem?

Heater is notorious on these – probably breaking down with load and temperature. Try the insulation test with it hot.

Power off, of course.

Re: Indesit D63 tripping RCD

Thanks for the reply Penguin. Sorry I’ve not got back sooner, but the darn thing has been working fine, then I’ve been away for a few weeks. I was waiting for it to go wrong so I could check it!

It has started playing up again, but an insulation test when hot comes back fine. What I have noticed is that there does not appear to be enough water to cover the element, and it is giving off a burning smell. However, if I disconnect the tube from the pressure switch, the water flows out of the ‘gun turret’ before it covers the element. Is this correct? Seems a bit odd that the element is not covered by the water (bit like boiling a kettle with no water in it!).

The current state of play is this:- Quick wash (5) cycle, machine fills for about 1 minute, gives about 1.5 cm of water above the filter. Wash arms run for about 2 minutes, then stop. Heater then switches on, and when it gets to the point when it starts smoking, the RCD trips out.

Sounds like the circulation pump motor is fried (no splashing water on the heater through the sprayarms). Or the start capacitor has failed. Unplug power if you are going to have a look yourself.

Then that’s your problem Pete, the main Circulating Pump! It should not stop during the washing process as the exposed element needs constant water deluge to stop it overheating. My guess is a new Motor and a new heater…..very costly….. 🙁

Re: Indesit D63 tripping RCD

Heater is causing the trip, but consider…….. the spray arms should not stop. The heat is taken off the exposed element by the showering water – no water, pretty much instant overheat. Investigate what the motor is up to. Use the pre-rinse programme (no heat involved) and see if the motor still only runs for 2 minutes, or whether it carries on. If it cuts out at about the same point, there is a problem with the motor. If it carries on, the problem lies elsewhere – switching, wiring, controls – something of that nature.

Stay safe, power off if doing anything other than observing.

Re: Indesit D63 tripping RCD

Thanks for the info guys.

I have tried it on pre-wash, and it is fine, so I guess the pump is OK. I’ll have to leave further testing until daylight tomorrow, the family would not be best pleased if I plunged them into darkness!

Cheers,

Re: Indesit D63 tripping RCD

OK, I’ve done a considerable amount of testing, and have some strange results.

I put a meter across the heater terminals so I could see when it switches in.

Program 6: Runs as normal to the end.

Program 5: Pump runs for a couple of minutes, then as soon as the heater switches in the pump stops. This happens every time, totally repeatable.

Program 2: Sometimes, pump runs for a couple of minutes, stops for about 1 minute, then the heater kicks in without the pump running (I don’t let it get past this point!)

Other times, pump runs for a couple of minutes, then stops for 10 seconds, runs on for another couple of minutes, heater kicks in (pump still running) then heater goes off again after 5 seconds. Machine then runs on to position 3, water is still cold.

Both of the above scenarios are repeatable, sometimes one, sometimes the other, but never any other combination.

Could this be the programmer playing up? The machine did have a new control panel fascia fitted under extended warranty about 18 months ago. Just after that we moved and the machine went into storage for 6 months, and developed the fault about 2 months after we re-installed it, getting progressivly worse. Could it be something the engineer did when replacing the fascia? (Warranty ended about 2 weeks after the fascia was fitted!)

Sorry for the long post, but I wanted to give as much info as possible.

Regards

It certainly could well be the case by the sound of it as no way should the heater come one without the circulating pump running. Also I’m still not at all sure about that heater you know? If you’re going to shell out for a new Timer and all the fag that entails, then it’s best to stick in a new heater whilst you’re at it!

Re: Indesit D63 tripping RCD

Yes, I am definately going to replace the heater, this one is totally fried now. I just want to find out why it went in the first place, as you say it should not come on without the pump running.
