Hotpoint DWF32 not cleanng properly – Help

[meggiedude]

I have had my Hotpoint DWF32 for about 8 yrs (I think). Its worked fine until recently.
Now the dishes are not washed at all. It finishes all the cycles OK and the insides are hot and look wet as normal, but the crockery is unwashed on both trays
I have removed and cleaned both rotors and the inside rotor feed tube unit. I have also checked the internal filters for blockages but can’t see anything obvious.
Is this likely to be an issue with the circulation pump – or something else.

Thanks in advance.

It could be the main circulation pump, or a problem with the heater box.

Not a simple machine to get inside but as it is a Bosch based machine well worth getting it looked at.

Thanks for that feedback.
You’re not kidding bout being difficult to get into into.
I struggled with it this morning. Managed to get the front bottom plastic kickplate and the metal plate behind removed so I could see the circ motor and drain pump, but could not get at them. The only thing I could get at was the circ motor capacitor.
Have verified that the circ motor and drain rotor turn by hand easily via the internal sump holes.
I don’t think that there is an issue with the heater as I ran the dishwasher empty this morning with a cleaner bottle inside. The 65deg wash produced the necessary heat to melt the wax seal on the bottle.
I’ll try another wash tonight, but I suspect the circ motor is working but not well enough. So is this likely an issue with the motor or the capacitor?

Also what I could do with knowing is how to get the bottom and sides of the unit off so I can get at the circ pump and check all the pipes are debris free.

Cheers.

The thread below may help.

you may have a problem with the flap motor in the heater box.

When you open the machine door is it spraying lots of water?

You may have restricted flow(blockage ie sump pipe/pressure chamber gunged up)
I believe the heater cuts out at low flow so you wouldnt get heat.

-my money is on the flap motor which is usually a heater assemble swap.

Sometimes the main pump impellor comes adrift. If you open the door mid cycle you may get splashed but you should be able to see if there is a decent flow of water coming from the spray arms.

A major strip down involving removing door, top, both sides and taking the inner tub right off to access base components.

My money would be on the same if the DWF32 actually had the motorised flap valve fitted.

Only fitted on the DWF61.

This machine uses a separate valve, part no: C00211376 which is not part of the heater box. 😉

Hi again. Hope you had a great Christmas.
Well I’ve opened the door mid cycle, and have not got wet. there is water coming from the rotors, but not I believe as much as there used to be. The rotors are turning (as I set them both at a 12 o’clock position and they have both moved from that) but they are not spinning as I open the door.
Some of the dishes are clean’ish (I wouldn’t say fully clean btw), on both top and bottom shelf, but some are plainly dirty with food still attached.
The water is getting hot as I get a good cloud of steam if I open the door in the middle of the cycle.
So if this likely to be an impeller issue as posted above or this valve you mention as above.
Only reason I ask is that its sale time now with deals at Curry’s etc.
I am not afraid of getting the tool kit to this beast, but don’t want to throw good money after bad.

Machine at least 8years old and if this is the first repair problem then hardly
“bad” money me thinks especially for this quality of machine?

Re: Hotpoint DWF32 not cleanng properly – Help

dont get carried away cja at 8 yrs old, the motor seal will prolly need replacing as well as the impeller if heavily used with rinseaid, but still id rather spend £150 on a dwf32 than £200 on a cruddy chinese made thing…. id even spend £150 on it even tho argos have a beko for £250…

OK Gents,

All fair comment, and I have taken this on board. Thanks for the help.

As it is I do have some good news.

I have cleaned all I could get at (without a major disassembly) and gave the d/w two more chemical enema’s (OK, dishwasher cleaner bottles). This seems to have made a big difference – in that is now washes and cleans the dishes. I still don’t think its 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} as good as it was – but its a whole lot better.
So out of a full wash I maybe have to clean one or maybe two dishes that have been left all day will food dried on them.

When it comes to rinse-aid etc – we generally use the all-in-one tablets, not separate salt & rinse-aid etc. Is this a bad thing?

some good news…

I suspect if you clean the pressure chamber and transfer pipe as detailed
in the thread below it will also help.

The pressure chamber is that big unit at the back of the machine – requiring a full disassembly?? (top,back,sides etc)
And the transfer pipe is the ribbed pipe I see from the bottom front of the machine ?? (this one I did have a go at cleaning – although I could obviously only get at the bottom part of it)

[CJAPeterborough]

Re: Hotpoint DWF32 not cleanng properly – Help

The pressure chamber is shown in the middle of the 2nd picture in the thread.

The ribbed transfer pipe runs out from it to the sump and can be pulled out
at each end for removal and cleaning.

If yours looks like the pics then after cleaning it should be like new….
