Thanks for all the help, it’s been spot-on.

I found the thermal cutout in the back of the cooker and it was fine on the multimeter. But I also found a spade connector that had come loose. No idea what could have caused it, but reattaching it securely fixed the fault. 🙂

Any ideas about the next thing I might look at?

Also, as it may be relevant – when the grill setting is on there is a fairly quiet mechanical whirring sound that starts up. The same noise could be heard when the grill was working properly. (It’s not the fan, that comes on with a separate ‘grill + fan’ setting.)

OK, I think the whirring sound is the cooling fan (as opposed to the oven fan).

Ace – thank you!

you need to remove the switch and check for damage

Dave

Thanks – you mean the selector switch for grill/oven/fan that’s set by the front panel rotary control?

[swansea_dave]

Thanks for your advice RocketMan.

The element has clearly had its day so I have ordered a new one. Hopefully that will sort it out, if not I’ll investigate further….

Re: Bosch WFB2005 interlock problem

Well, I changed the interlock and the machine started to work, apparently fine. But I ran a short wash program and when the machine had finished I realised that it hadn’t filled with water. I have tried a few different programs and the drum turns, spins, etc but doesn’t fill. It was working perfectly before the door interlock problem.

Any suggestions gratefully welcomed!

Re: Candy C4100

Hi Penguin,

Many thanks for all of your help, much appreciated.

The new part hasn’t sorted the problem. After 10 years use and a few successful repairs along the way I have decided to cut my losses and ordered a new Bosch.

Cheers,

Dave

Re: Candy C4100

The new part has the following numbering for the six terminals: 11/12/14/21/22/24. The old part has 1/2/3.

Does this mean 11=1, 12=2, 14=3?

Cheers,

Dave

Re: Candy C4100

Having ordered the correct part from UKWhitegoods I was sent an alternative part and my query met with the following response:

QUESTION: “I received my order today but I think I may have been sent the wrong part. I ordered a pressure switch number 92741248, which is also the number stated on the invoice that accompanied the part that was sent, but the bag for the part says that it is part number 92741230.

The part itself is stamped 9274123. It is much larger than the original part and also has 6 >electrical connection tabs (4+1+1) whereas there were only 3 electrical connection tabs on the original. I had sent you a picture of the original at the time when I asked about availability of the part (copy attached).

Is this an alternative part? If so, how should it be wired up in comparison with the original? Or was it sent in error?”

UKWhitegoods ANSWER: “92741230 is the Candy replacement part for 92741248. The numbers next to the terminals should match the original normally (swap the leads number for number).

If not, asking in the forums may help as Candy will supply no technical support.”

I am stumped by this response. There are no numbers that match up on the two parts. If anyone can advise I’d be very grateful.

Thanks,

Dave

Re: Candy C4100

Thanks Penguin,

The switch is definitely the culprit. I took it out of the system and connected each of the end terminal wires in turn to the central terminal wire. Combination 1 lets it fill as normal (except that it would keep on filling indefinitely I think!), and combination 2 lets it pump out the water.

I’ll email your link for a new switch. I’ll let you know how I get on.

Thanks again,

Dave

Re: Candy C4100

Well, dried the switch thoroughly, put it all back together ……. and there is no difference. As I manually advance through a cycle I can get it to start to fill with water, briefly, and to drain at the end, but it won’t fill properly.

Is there also a float switch lurking anywhere on this model? I understand that this is sometimes the case.

Thanks,

Dave

Re: Candy C4100

Hi Penguin,

The tube to the pressure switch had water in it, so I’m drying the switch out tonight. When I blow down the tube the switch clicks, so I guess its OK? I’ll test it tomorrow evening.

When I disconnected the tube from the switch and plugged the end of the tube then the machine still wouldn’t fill, which wasn’t what I expected (?)

Sick of washing up already. Its a good incentive to sort the job out….

Cheers

Dave

Re: Candy C4100

Thanks Penguin,

I took off the black triangular plate on the underside of the sump moulding but there wasn’t really a tube attached to it only a short hollow protrusion of about 2cm. I couldn’t see or feel any moving parts.

The top of the chamber that the plate covered had two small diameter tubes coming out of it. One went to the water inflow mechanism and one went to a separate component attached to the underside of the machine.

After thoroughly cleaning the chamber and checking that the tubes were clear, the machine is still behaving as previously. Any ideas?

Thanks again,

Dave
