ParticipantI don’t have the model number on this one. Machine is only a couple of years old. Due to visit on 27 March.
I’ve been trying to find similar problem on the forums, to no avail.No error code mentioned.
Apparently, the machine works, but on only one program does it behave normally.
On other programs, it fills, spins slowly, fills some more, timer goes down, but doesn’t do a proper wash.I have requested more detail, but in the meantime, has anyone come across something similar?

Moderatorthat does sound an odd description
prob make more sense when you see it
which programme works ?

ParticipantRight, so got more info from the customer: model number is NSWM843CWUKN, industry code 769991609841
The program working correctly is Full Load 45 min
On the other programs it keeps adding water and sloshing the laundry around.This makes me think pressure system problem. If it was filling for a set time on the 45 min cycle, but on the other cycles using pressure switch readings, then if the pressure system is not working properly, that behaviour would make sense.

ParticipantI hadn’t thought of that though wouldn’t it be syphoning out on the 45 min cycle too?

I guess it could still be syphoning out if it’s not using the pressure switch readings. But would there be enough water left to do a wash??!

Moderatorwith a short programme and if its just trickling out it may not have time to refill if water drops
was thinking the short programme might be less load but just checked and its a full load programme
if it was the pressure sw problem i would expect the load water to get higher and higher throughout the wash so is the water load overfilling on the faulty programmes ?

ParticipantMore info, the customer had failed to mention the machine drains in between the fills.
So the sequence is fill, agitate the clothes a bit, then drain ad infinitum.
So there’s no overfilling.Still thinking pressure system. Or board problem, or wiring?

Moderatordont think pressure system as no error codes
wiring maybe but still no error
earth faults is another long shot maybe
and if its the board unless you can programme boards its a hotpoint job

ParticipantAre you thinking the program on the chip? If so, ASWO sell programmed boards, all down to whether customer wants to pay the money.

Moderatorproblem is if it does not cure it
if its only a couple of years old suggest customer claims on part guarentee which will be cheaper if the board has gone as the board is about the same as Hotpoints labour charge. Board may just need a re – programme which we cant do without spending out on gear we wont use often

ParticipantThey say they inherited the machine, I assume therefore they don’t have access to the Hotpoint parts guarantee.

I see that throws a spanner in it
problem we have as always is we dont know the cause
think as a start you could swop the pressure sw as they are less than £20

ParticipantThanks Dave, I’ll have a good look at that pressure system first, and take it from there.

ParticipantWent to this machine this morning and turns out as you first suggested that the water was syphoning out. The drain hose was too far down the drain pipe.
All programmes start by filling slightly, the machine sits there for a while and then it pumps out for a couple of seconds (I assume it’s to get rid of the previous wash’s residual water). After the pump stopped, it would carry on emptying at this point.
The reason it was not doing it on Full Load 45 min is because on that programme, it doesn’t do the short pump out.
