1. Fill levels seem low: normal level wash / rinse about 70 mm of water in drum – thats a little below the rim of the inner drum. High level rinse (wool) 92 mm in drum – still well below the door. Does not seem to be rinsing as well as it ought. I can’t remember what it was like new.
I suspect the pressure switch has drifted over the years – the pipe to the drum is clear btw.
Does anyone know the correct levels fot this m/c?
2. The part appears to be C00199993 / 1602438. I can’t find on the ukw site. Do you do it?
You show C000200459 / 1602538 but this is for the wm51 thru 56 and 82 series I gather it’s described as “pressure switch high”. Now the switch on my wm64 is right at the top of the case – I’ve no idea of the internal layout of the 51 series – but the pictures i’ve seen of the two switches look identical – same mumber of terminals. shape etc.
I was wondering:
a. Would this “high” device work and give a slightly higher water level than the correct one?
b. If so what are the implications, especially for the water seal to the tub bearings?
c. Motor loading? THis beast has been through more GDA motors than i’ve had hot dinners and we don’t overload. (I’ve resorted to cutting a 5 inch hole in the back and fitting an extract fan – 20deg C motor temp drop washing a set of towels! So far so good.)I’m musing besause the girls have both got sensitive skin AND need dfiferent powders. Every wash gets a super rinse and then a second rinse. A little more water might help.
Yes, I know, I need an ISE. Promised ourselves one when we move house.
Re: Hotpoint wm64 water level low?
Almost unheard of for a pressure switch to ‘drift’.
I would be carefully checking the pump and the sump hose filter, also if it is plumbed into the undersink plumbing then check for any obstructions in the outlet hose.
If the drain pump sounds a little noisy then it could well stick intermittantly leading to poor rinse and indeed excessive motor wear.I assume you have had the odd motor but to have had the number that you seem to suggest is not common, motor overloading can also be caused by drain out obstructions.
I have many hundreds of these machines on my patch, some over 25 years old. The basic design and certainly the motor on yours is similar to machines from well over 20 years old, I cannot think of a single machine on my area that has had two motors fitted to it.
WATER LEVEL CONTROLAll models use a single level pressure switch for all prewash, cotton and synthetic programmes.
The only time a higher fill level is required is for either the Wool programme or if Super Rinse is selected. To achieve a higher level fill,an intelligent timed filling system is used.
Each time the machine fills, the controls measure the time taken to fill from empty to the pressure switch setting, the time taken to complete the fill determines the extra amount of water to be added.
For the the first fill on the Wool programme, or if Super Rinse has been selected, a gentle unidirectional tumble takes place while filling, this to ensure the wash load has fully absorbed water prior to the pressure switch setting followed by a calculated timed fill to a maximum of 3 minutes.From this it follows that if you try the machine empty you will not get an accurate idea of how much water is going in during a proper wash cycle with clothes in it.
Re: Hotpoint wm64 water level low?
Hi there, I am struggling with very low water levels in this machine and me and the mrs are constantly itching. (it is not rinsing very well)
The super rinse button does increase the water level to within a nick of the door bowl. We’ve just started using that.
I see the pressure switch seems to be ok and the pressure switch pipe is clear.
There is a small amount of noise whiring bearing noise from the drain pump, but I’ve never really listened out for it before so I don’t know if this is normal.
Also, how could it be the drain pump, if when it drains the drum, it seems to do so quickly and I can hear the water gushing down the sink plug hole?
Any help is greatfully appreciated.

Try changing detergent brand? Also ensure wash each garment on correct cycle as per garment wash label.
Re: Hotpoint wm64 water level low?
With all due respect Martin, we’ve been itching since October – do you not think we would have tried different powders? Also, it affects everyone using this washing machine.
Re: Hotpoint wm64 water level low?
All of the things your machine is doing appear to be correct, are you in a soft water area? you could try making a dramatic reduction in the amount of detergent you are using. I this area I use no more than a single tablet, sometimes even half a tablet, clothes perfectly clean and no soap residue left on the clothes.
If it was not draining out properly you may have a problem but draining too quickly is most certainly not possible.
Re: Hotpoint wm64 water level low?
Not particularly soft, nor hard here in Bournemouth. Funnily enough, with the last load, I cut the end off the ariel plastic liquid tabs thing and poured 1 third of the liquid into the wash (knowing that there was also probably residue in our towels as well) and on the third rinse (the super rinse) I noticed a very small amount of suds, even with this low amount of added soap.

How often do you carry out a ‘Service wash?’
