Our Candy C4100 dishwasher won’t fill with water. The controller seems to be working OK as the element heats up and the machine sprays what little (dirty) water remains in the bottom of the machine around the interior.
If I turn the programme to the drain part of the cycle then it initially starts to pump then stops after a second or so (possibly as there is next to no water inside?)
Could the problem be the float/float switch? If so, can someone please indicate where this is located.
Thanks in advance for all advice,
Dave
Re: Candy C4100
The heater will only work if it thinks it’s full of water. This uses the “old” water level system – proceed as follows.
Unplug and tip the machine back to a good angle. Locate a black triangular plate on the underside of the sump moulding. Undo the screws and pull out the plate and tube. It willprobably be coated with years of muck and goo – clean thoroughly, then clean the chamber which it fits into.
It’ll probably work after that.
It’s possible that the level switch has failed in the closed position, but it would be most unusual.

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
Re: Candy C4100
Bum……
Right, the two skinny tubes feed the level switch and the pneumatic shut-off on the fill valve. Follow them, especially the one to the level switch. If you gently pressurise that tube, you should hear the switch click. If it doesn’t, the switch will have failed. Check both of tubes to ensure that they haven’t filled with water, it’s worth blowing back through to ensure that the spigots which they connect to on the air chamber (the bit you’ve just cleaned) are clear.
See how that goes.

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
Best way of clearing the switch is to remove it and shake violently – make a diagram of where the wires go first. Switch itself can fill with water.
If this doesn’t fix it, you’ll need to arm yourself with a multimeter and start testing.
Fingers crossed,

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
92741248 is the part number for the level switch – it has to be the prime suspect. Can’t find a price for it – drop an email with the part number to spares@ukwhitegoods.co.uk to get things moving.

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
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
Part supercessions do occur, regularly. The terminals are all numbered, usually 11,12,13 for the first level, 21,22,23 for the second, etc. New switches are often numbered 11,12,14. They are moulded onto the casing, so can be quite hard to spot.
HTH,
Penguin45.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
Correct….. I apologise, some single level only switches did 1,2,3.
Hook it up 1=11, 2=12, 3=13 or 14 and you should be on a winner.
