TOC for Hotpoint WD640

[kwilby]

Could someone provide me with a link to the above part please, I assume that I can buy one from UKW?

Many thanks.

If it is the small round black one then THIS is what you need.

Bear in mind that it is likely to fail again in no time at all unless you have fully cleaned out the dryer filter and housing and made sure the fan will spin freely.

You have to dismantle to change this stat.

If those things are OK then it may last a few months. :rolls:

Thanks very much for that info. The new part lasted 3 weeks and I’m not a happy bunny.

Can I just make sure I looked where I should have to clean? I split the aluminium fan casing and there was no lint in it and the fan was free to spin. Is there anything I’ve missed or do you reckon the part was faulty?

Many thanks.

Re: TOC for Hotpoint WD640

Part was almost certainly OK. I will not change these now due to the certainty of failure within a very short time unless the customer accepts the repair with no guarentee whatsoever.

The whole of this Indesit heater assembly that has been grafted onto a Hotpoint machine has had countless modifications over the past few years.

There used to be a complete heater box kit that did improve the reliabilty a little. I am not sure if it is still available though. I have heard of some engineers removing the filter, flushing hose and disconnecting the flushing valve to help cure this fault.

Sad fact is, its a very flimsy, poor design. 😥

Re: TOC for Hotpoint WD640

Hi Rob, I tried to enter that number in Partfinder and it didn’t recognise it, is it still available?

If I enter it at Masterpart it comes up as an element. ❓

ill check it monday….

we got rakes on shelf, so they are available

I think that is open to debate, 😛 😆

I did have that as the part number myself but it is not now recognised on Partfinder or at Masterpart, must be old stock.

Thats quite a decent price from eSpares, not their usual OTT price.

Re: TOC for Hotpoint WD640

So what’s the bottom line here guys? Is the part faulty? Presumably my statutory rights entitle me to a replacement?

Thanks.

Hi Kwilby,

Of course you can get a replacement but, as usual with these things, I’d expect (as both Jim and Helo do) that there’s an underlying cause and that a straight replacement won’t solve the actual cause.

When a replacement part is fitted and, plainly works as you say, but only for a short period then something else is causing it to fail prematurely.

Between just the three of us on this thread there’s decades of experience and I’d bet quite comfortably that between us we could count on one hand the times we’ve had a new part fail without something causing it to fail. It is so rare to happen it’s unreal.

The part you got was a thermal cut out, that means that is is designed to fail when safety is compromised, as in the dryer overheats. To find out why it’s failed you have to work out why it’s overheating.

With washer dryers it can be…

Dryer control stats
Condensate chamber blocked or partially blocked
Door opened too soon with no cool-down allowed
Fan motor failure

And those are the easy ones to find.

We really don’t like washer dryers. 😉

Hi kwatt and thanks for replying.

WRT number 2 on your list, can you confirm that that is the aluminium casing on the top where the fan is? That casing is clear of obstruction and the fan rotates freely. Might there be a blockage elsewhere?

WRT number 1 on your list, is the thermostat the other “round” device in the casing and could I test it with a meter?

I can hear the fan working so I can discount that one but opening the door too soon will happen often despite attempting to re-programme wife.

Thanks again in anticipation.

Is this an option for me? Could you provide any guidance? I have to say that I’ve no idea where the filter is 😕

Thanks for your patience.

Re: TOC for Hotpoint WD640

Hi Kwilby,

I’m not as familiar with that washer dryer as IADOM or Helo are but, number two on the list is not the aluminium fan housing. It is the section where the hot air from drying cools, condenses and falls back as water to be drained. If that is blocked, even partially at a critical point, the dryer will overheat for sure. It’s often a large plastic chamber at the back of the drum, but there are other ways.

Dryer control stats, there’s usually always at least two on a washer dryer and one thermal fuse or cut out for safety. They will usually be mounted on the fan housing somewhere.

Although you hear the fan motor running do check that the dryer fan is actually securely mounted to the fan motor shaft as it’s not unknown for them to come loose and the fan not to spin up as it should. If that happens, you will get an overheat.

Thank you K, I will attempt to check all of those things, although there is no rear panel on this machine and it looks as if you have to remove the entire casing in order to gain access.

Could someone confirm if this is so? Any other pointers would also be gratefully received.

Cheers.
