Our dishwasher is making a nasty grinding racket at specific times in its program, almost as if a bearing has gone in something or there's a bit of gravel in a pump. I'm trying to diagnose it.
It happens for about 30 seconds immediately on pressing go on the cycle, and about 3/4 of the way through the cycle briefly again for about 10 seconds depending on the cycle, but in the main this is the pattern. When I say immediately, I mean it's the first thing the dishwasher does after the door has closed.
It doesn't do it when it's washing normally. All the rotating spray arms are clean and fine. The filters are clean.
So what does a dishwasher do straight away when you press go and shut the door? I get that, I'll know what to fix.
I imagine it activates the pump to get rid of any standing water?
"Lemon pip made it to the impeller" ?
I think I had similar... Was bit of glass stuck in the impellor sump thingy.
Actually watched a good dishwasher video on YouTube the other day. More relevant to North American appliances but interesting non the less (the wife would disagree)
She says 'Stop pressing me there or you'll make your own tea'.
IGMC.
The very first thing?
something moves and jambs the washer arm and you wait 2 hours to find a half washed load.
as scotsroutes says - I imagine it activates the pump to get rid of any standing water
it mght be something jammed. Usually if you lift off the main filter, then the finer filter, there is a clip or something you can unclip to get in a remove anything that's jammed. That's how it is on our bosch but it looks like most makes use a variety of parts from different sources so yours might be the same
Aye, pump for sure.
I spent boxing day stripping the bugger to bits (the joy of integrated appliances) only to find the impeller is in a sealed unit, canny get into it at all! In the end the only way I could clear (it was full of water and wouldn't pump away) was to get the lips round the outlet hose.
Lovely.
I also think it's the pump - and dishwashers have two pumps, one that circulates the water round during the wash cycle, and one that empties the water into the drain - it's the emptying one that starts the process (and I assume kicks in 3/4 through at the end of the washing phase ready for the drying).
On ours (Bosch) it definitely drains first. There is a tank that the drying condensate collects in. I had to change the switch on the bottom of the tank, and when testing the fix with side panel removed, I noticed it always ends the cycle leaving water in that tank.
We had a bit of lamb bone in the impeller and it sounded just as you described.
Gives me £200.
I turn the tap on ! 🙂

you have my condolences and admiration in equal measure
I would have just moved house
Desperate times call for desperate measures Mac.
There was an awfy pile of dishes awaiting processing.

I have an air compressor that I once used to do something similar to a friends dishwasher. I absentmindedly span the valve right round to max pressure and blasted the outlet. It was VERY effective at clearing everything that was clogging the pipe and blowing it back into the dishwasher. Thankfully the door was shut because when we opened it looked like the dishwasher had had a dose of the shites. I should point out this was a rental place and wasn't a good rental place.
I would not liked to have put my mouth anywhere near that pipe.
It is not for man or beast to know what happens when you close the door, and henceforth shall remain a mystery.
(it's probably the drain pump though)
Yep drain pump. Had this on ours a couple of years back. Was part of a plastic pen lid. The joys of having kids.
