Dishwasher Help Forum

[Gareth1]

Hi,
This looks a great board, having had a look around. Hope someone might be able to help me out. I've got a Lamona HJA 8631 fully integrated dishwasher. It's about 14 months old and has suddenly stopped draining at the end of a wash cycle.

I've scooped and soaked the water up, removed the filters and given them a good clean. I then started a really hot, empty cycle to see if that blasted through. Unfortunately, exactly the same result. Cycle ends, water all left at the bottom. I had a search online and found a few posts for this kind of problem with the HJA 8630, which I'm assuming must be a closely related model(?) In those cases the problem seemed to be the pump having died or got blocked with debris.

I removed the kickplate and found that the tray at the foot of the machine was filled with a layer of water. I've soaked that up now. I'd read a tip on the 8630 that if you held the 'go' button for 3 seconds down, the light starts flashing and then if you close the door the machine will drain. I don't know if that's the same with the 8631 but I gave it a go. The light does start flashing, then if you shut the door, I could hear a quiet humming noise from down by the pump, but no draining!

So I'm thinking the next step would be to remove the pump just to see if any debris can be easily identified and cleaned. But I'm a bit lost at this point. Posts about the 8630 seem to suggest there's no retaining screw and it just twists off. I can't see a screw on this model either, but I'm not getting any movement at all trying to twist it. Having said that, I'm reluctant to give it some real welly in case I'm doing it wrong and there is something I should be unclipping/unscrewing or whatever.

If anyone could give me a pointer on whether or not I'm going at this the right way, and if so, how I might remove the pump, that would be very much appreciated. I'll try to upload a pic that shows what I'm looking at. Any advice gratefully receieved.
Cheers,
Gareth

Do a simple continuity check on the drain pump. If it's open circuit, there's your culprit.

If not, then strip it out and check it over.
