Re: Hotpoint WD420 doing strange things!
Little update…
Disconnected then tested heater element, which was fine. Reconnected, then started a wash cycle so I could test the supply to it, which was fine too.
Then the bloody machine went through the cycle as normal with no problems! So it’s working again!
Bad connection maybe, or it was just having a bad day and wanted to take the p… out of me 😆
Drain pump is starting to get rather noisy, so that will get replaced next week hopefully.Anyway, thank you for your help. Much appreciated.
Re: Hotpoint WD420 doing strange things!
I’ll go check that as I never thought about the heater!
Thanks Martin.Re: Hotpoint FDW60 Problem…
ily0405, I don’t understand why you’ve quoted that!
Little update: Removed the circulation pump and wired it up on the bench. Runs perfectly.
So I’m still thinking it’s a little valve or switch that is stopping it working (as the PCB tests ok).
Can anyone tell me which switch/sensor/valve would stop the circulation pump from working please?
Would the water level matrix thingy have any such effect if it’s a bit gungy or blocked? I only mention that as I had the machine on it’s side when changing the waste hose, so wondering if any sludge has moved whilst it was on its side.
It has to be something to do with me replacing the waste hose, as it worked fine before that.
Help!Re: Hotpoint FDW60 Problem…
I’ve had another play with the machine. There is a supply to the pump motor and capacitor. The supply is live when the machine is powered on.
Am I right in thinking the PCB controls the switching of the pump? Are there any switches/sensors that will shut down or affect the pump?
The return cable from the motor to the PCB goes through what looks like a motor operated flap valve of some sort, which is located in the pump (impeller) housing. Can anyone tell me what this valve thingy does please?
I’d really like to rule everything out before I buy a new pump.I know I should really consult a professional, but I really don’t have the funds to do so, which is why I’m pestering you great folks on here. My washing machine is still going strong thanks to the information given to me on these forums.
Thank you again if you have already helped me, and thank you in advance for any further information offered.
Re: Hotpoint FDW60 Problem…
I can turn the circulation pump by hand. There is a very slight restriction but I imagine that’s just the seals gripping the motor shaft, as it is very slight.
I haven’t checked cable continuity between the motor and the board yet, but have checked the connectors. The motor also test ok, with no short or open circuit. I don’t have anything to test the capacitor.
Do the motor run capacitors fail regularly? If the motor is trying to pull too much current, will the system recognise this and shut it down?
I think I’ll have to test the motor to see if it tries to start during a wash program.
I hope it’s something as simple as a bad connection somewhere!Thank you both for your help so far.
Re: Hotpoint FDW60 Problem…
No, it just empties again. It seems to get to the point where it would start washing but there is no sign (or sound) of the pump starting.
Re: Interlock; Hotpoint WD420
Well, you guys were spot on!
I took the motor out tonight and had a look. The brushes weren’t bad, but the slides were full of carbon, stopping the brushes from moving.
After a good clean I put it back together and it worked!
I had assumed that a motor fault would have it’s own fault code, with flashing lights, bells and whistles, so I didn’t even think of going there in the first place.
(The original problem was a slightly charred interlock and a blown board. The second fault showed exactly the same symptoms, which is why I thought it was another interlock fault!)Many thanks once again everyone.
Re: Interlock; Hotpoint WD420
I didn’t know that. I’ll go look.
Many, many thanks helo_75 and DDSDDS. Your help is much appreciated.
Plus, I’ve learnt something new 🙂Re: Hotpoint WD420 – Water inlet valve wiring
I have just realised what I’ve been doing wrong.
I was looking at the machine from the viewpoint of how I expected it to work, rather than how it was designed to work!I was expecting the hot inlet to go through the main wash, when in fact it looks like it goes through the softener compartment! The pre-wash and main wash are cold feeds, so the third feed must be the hot through the softener compartment. If this is the case then they all work as intended.
Therefore the cold feed to the (dryer) filter will work when the softener cycle is running (as they are both connected together electrically at their respective valves).This is not how I would have imagined the system would work (from a logical point of view)! Which, as I said, is where I went wrong!
So, many, many thanks once again for everyones help, and apologies if I have been a pain in the bum 😀

in fact, that dryer was modified
i take it it has 4 coils on the valve
later versions removed the 4th valve
is there another grey hose, going to the back of the tub?
Yes, three on the cold and one hot.
There is another grey hose. Goes from the same valve to under the filter, into the tub.Re: Hotpoint WD420 – Water inlet valve wiring
The hot water isn’t connected to the filter. The hot goes straight to the soap dispenser along with two cold supplies.
The filter is connected to another cold inlet, but seemingly never receives any water. The only water running during the dry cycle is short bursts (cold water) into the soap dispenser, which is why I think there might a problem with wrong connections (electrical, not plumbing). Shouldn’t that short burst go to the filter?Re: Hotpoint washing, and washing, and washing….
Just thought I’d give an update.
I replaced the main heater element as advised and the machine now seems to be working properly.
So thanks again to all that helped me with this.I did however notice something that I think is wrong, and I’ve made a new post here: http://www.ukwhitegoods.co.uk/modules.p … 298#250298
Any help with the new problem (if it is a problem!) will be greatly appreciated.
Many thanks.
