Any one up for a Challenge – AEG Favorit F88070Vi

[scanner22]

Hi all,
I have an AEG Favorit F88070Vi with a wash pump that has stopped working.

When the cycle gets to the wash part, the motor makes a humming noise without spinning

I took the motor out, and the front bearing was rusted out – it would still turn but a bit stiff. I replaced the bearing and put it back in and still had the same failure – humming with no turning.

After a little bit or research I then replaced the capacitor but still the same fault.
I have checked the windings and they have ~50ohms on one and ~80ohms on the other which seem ok?

So I am a bit stuck. Can anyone help please??

Many Thanks
Ivan

Is the pump free to turn now? I’m guessing it is still too tight.

Hi, I checked that last night. I took the casing off the impleller and it seemed to spin freely – there was a little bit of resistence from the seal but not enough to stop it from starting. I even tried spinning the motor shaft whilst it was powered (from the rear with an insulated screwdriver on the small round metal part where the tachometer (I assume it is the tachaometer) is) to try and get it running. I couldn’t give it a big spin but did turn the shaft over yet it did not start then either.

I’m starting to think that even though the windins seem ok, they may not be under load?

Still stumped!!

Motor start capacitor?

A 3uF one is used as here: http://shop.ukwhitegoods.co.uk/cap03-wa … -capacitor

If not, could well be the motor is kaput.

Hi Kwatt,
Yes I have changed the capacitor – and I think it is a start/run capacitor of this model? Sorry if I was not clear above.

So probably the motor is gone?

That would be the best guess I reckon.

Ok, so I replaced the wash pump water is being pumped around now :).

However, I now have another problem – the top spray arm is not spinning. Water is comming out of it and the holes are not blocked. I’ve put the arm straight on, waited for a few miniutes and opened to check, and it hasn’t moved. I can also tell by the dirty marks still on the wall of the dishwasher where not wash water is getting to. I will check the feed tube but any ideas on this? Thanks.

I relooked at the top spray arm and there were a couple of jets that were still blocked and this was enough to stop it from turning. As of last night it was all running ok!! 🙂
