WF321 Impeller not spinning

[crashnstick]

Hotpoint WF321 was overflowing out of the drawer, so realised it wasn’t draining after trying to start it 3 times when it stopped mid cycle.

Managed to manually drain it, get load out and removed the white impeller cover bottom right. There were 3 coins and a few hairclips in there, checked the impeller spins, which it does.

Put it on a spin cycle and watched the impeller, nothing.

So my question is, how do I tell if it’s the pump burnt out or the control board? Want to avoid ending up buying both parts if I can.

Thanks in advance if anyone can help.

What you’re looking at and how to test it etc is here:

Re: WF321 Impeller not spinning

Great, thanks K. Hadn’t removed the pump yet and had a feeling there’d be a load of terminals. Continuity test across 2 terminals seems simple enough even for me, I’ll whip it out in the morning and take a look. Thanks again

Re: WF321 Impeller not spinning

If the pump has actually burnt out you can usually see signs of overheating or charring on the pump windings. Sadly if the pump has burnt out then in most cases it will have taken the main pcb with it. 🙁

Also worth noting that if some of these machines are tipped back whilst still full of water then it can upset the pressure switch which will then need resetting.

Re: WF321 Impeller not spinning

Thanks iadom.

Pump tests as open circuit and there is black residue (almost like burnt sugar) on one of the windings. Clearly pump needs replacing, is there any way to check the board? Don’t want to buy a pump only to find I need a board too, by that point it’s getting uneconomical and may as well buy a new machine.

Is the main pcb the one down the back at the bottom? I actually had that out last year to replace a capacitor which is apparently quite common on these. Given that I’ve done that once, is there a component on the board that I’d need to replace or is it a case of a whole new board?

Thanks for all the help chaps (or chapesses)

Re: WF321 Impeller not spinning

Forgot a bit, didn’t tip it while full, but if the pressure switch does need resetting is that something I can do?

Re: WF321 Impeller not spinning

If you didn’t tip it back then the pressure switch should be OK.

A careful visual inspection of all the components on the board, especially the resistors is all you can do.
Sending the board to someone like EMW electronics possibly the best option if it is damaged.

Re: WF321 Impeller not spinning

Thanks again iadom.

OK so I want to buy the parts on here as clearly you guys don’t offer this support for the good of your health.

The pump seems to be this one……

https://shop.ukwhitegoods.co.uk/c001453 … drain-pump

But it says suitable for wf321p…….my machine just says wf321, is this relevant?
For £20 or so I’m going to take the chance and just order one, if it turns out the boards gone too roughly what do EWM charge for a repair? A new board looks to be £100+ and it’s not worth spending that, will just replace the machine as it’s getting on a bit, don’t want to end up with a “triggers broom” scenario as all the parts fail. 😆 😆

Cheers

Re: WF321 Impeller not spinning

The ‘P’ is just a colour variant . The pcb may be £100 but that doesn’t include the cost of the £20 smart card and smart card reader needed to program the new pcb.

Most of EMW’s current prices are on their web site.

Strange as it may seem we do offer our help freely and without any other motive. The spares shop sales make not a single penny for me. 😉

Re: WF321 Impeller not spinning

In that case iadom you are a true gent. Thanks so much for your help, I thought the spares side must pay for this, very good of you.

Re: WF321 Impeller not spinning

Quick update on this, fitted new pump but still no life from it watching the impeller on spin cycle. As iadom had warned me the boards often go at same time and told me where to get a refurbished one, got one ordered from EWM. Came promptly, plugged it in and bingo!! Machine fixed for about £70 and a nice sense of achievement.

Couldn’t have done it without the help though, thanks very much!!
