Having recently repaired this washer/dryer, as I was testing it I noticed it wasn’t taking in hot water.
When I looked a little closer I noticed that the wiring connection on the hot inlet was connected in parallel to the cold inlet for the dryer condensor!
Is this correct?
I can’t see why it would need hot water when drying!
I also found that during the drying cycle cold water is added through the soap drawer (short bursts) and not through the condensor (that I could see anyway).
Are my inlet valves wired the wrong way? Does anyone have a wiring diagram I could look at please?(When the washer was a couple of months old we had to call an engineer out as the machine wouldn’t fill with water. He replaced the valves and said all was ok. I noticed the other day that he had written in pencil on top of the soap tray ‘red link hot’, which is how the hot is connected, in parallel with the cold condensor valve).
Re: Hotpoint WD420 – Water inlet valve wiring
I’m sure that your machine is wired correctly. Hotpoint have made a number of changes to this type of washer dryer.
The original machines used to only fill hot if the machine had to top up more than four times on the initial fill sequence.
The newer versions of this model are cold fill only now.
the hot water to the dryer is purely to wash the filter, to keep it clean of fluff
thats the only reason its there
got nothing to do with the wash, that just uses cold!
we’ve discissed this in length before.. there are no known machines with hot and cold fill for a wash
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?no
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
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 😀
