Bosch dw – SGV53E33GB/10 – drain out after heater

[twicknix]

This dw who I thought a simple job on replacing jug impeller as the owner says the tap light was on and it was doing the fill/drain cycle. Replaced the impeller, ran on 45 deg quick wash, seems OK as it heated up the water to correct temperature, then it drains to make way for the rinse cycle but it didn’t as it was doing the fill/drain cycle.

No leaks on base, clean as a whistle. The insulation reading from the plug is lower than I would have liked, 725mohm which increased from 100 earlier on, the last visit was 410.

What am I looking at? Faulty programming that need recalibration meaning I need to send it away for it?

The dw is 7/8 years old.

My guess from what you say is that the drain pump is the caution here.

Edit: one other thought is the float mushroom? Does that operate OK?

The mushroom works perfectly fine.

it’s somewhere between the drain pump and fill, it got stuck in a loop after the wash/heater/drain prior to rinse. The mushroom works fine as I checked it which responded when lifted.

Then I’ll stick to my first thought, a dodgy pump.

what you mean dodgy drain pump? replace pump or what?

As I said, I suspect the drain pump is clapped out. 8 years old and I would certainly inspect the pump. Probably drains cold water with no problem but soon as it has to pump hot it jams.

Certainly needs checking out at least. 🙂

I am confused as it is working when it’s hot just that it reverted itself to fill/drain cycle similar to faulty jug impeller but right after the first wash before it was meant to start filling cold water in time for the rinse cycle. My point is that the pump is working fine so how can it be dodgy? Are you saying that the hot water is impairing the pump performance that it was unable to correct itself in time for the cold fill for the rinse cycle?
