Re: Neff S5943X2GB Integrated washer being a pain!
Can anybody confirm whether that the second 2 pins on the NTC should read anything?
I will get a replacement sensor but just want to be sure.
EDIT: with the conector disconnected I get 68K Ohms from the sensor.
I have monitored the element pins whilst It was running and I never see any voltage on them.
Any idea where to go from here.
Re: Neff S5943X2GB Integrated washer being a pain!
Just to tidy up this thread.
I have bridged the level sensor with still no heat.
I have bridged the NTC with a 48K resistor. Still no heat.
I have no voltage on the heater pins when the heater should be running. If I have ruled out the water level switch, the NTC and thermostat and the element itself then it must be wiring or PCB?I have checked the PCB for cold joints, but maybe the relay on the board is broken?
Re: Neff S5943X2GB Integrated washer being a pain!
I have just run another test run. It does get maringally warm. The water isnt stone cold, which makes me thing the heater is working to a certain extent?

A common failing for sure. :tup:
Re: Neff S5943X2GB Integrated washer being a pain!
Just did another test, with the multimeters on the heating element, and its getting 240 volts…. im completely stumped now.
Re: Neff S5943X2GB Integrated washer being a pain!
When it washes is there plenty of water sloshing around in there? And do the spray arms alternate (switch from top spray to bottom spray) every 55 seconds?
Re: Neff S5943X2GB Integrated washer being a pain!
Large amounts, both spray arms appear to alternate correctly.

Also to confirm what I have already done:
Heater element has a resistance of 23 ohms.
The pressure switch works properly
The NTC/Thermostat at the top measures 0 ohms (closed) and 50Kohms at room temperature.
The PCB shows no burnt traces or dry solder joints.I have ran the machine with a multimeter on the heating element and do see 230 volts for a bit. I didnt wait to see how long for however.

Would advise crock clips to enable a longer test period. 💡

How long should I watch it after starting, its pretty boring 🙂
Re: Neff S5943X2GB Integrated washer being a pain!
On a ‘Quick Wash’ cycle the heater will come on within 10 mins or so (IIRC) and remain on for a good 20 mins. ( or there abouts). So crock clips the best/safest test method during that time obviously. 😀
Re: Neff S5943X2GB Integrated washer being a pain!
New info – I sat and watched it, it turns on, drains for 20 seconds, I hear relays clicking and it fills with (some) water, where it then attempts the rinse. It is barely dribbling out of the spray arms. If I fill it then then close it it rinses properly, then does the same thing on the heated wash section.
If I then pour a couple of liters of water into the dishwasher and close it, it washes properly and heats properly as well.
Is there a float sensor that needs adjusting? All water inlet screens are clear. It is pumping some water in when needed, just not enough it appears.
Re: Neff S5943X2GB Integrated washer being a pain!
The normal water level should just cover the salt container collar (not the salt cap). From the sounds of it the problem is with the fill process and you need to observe and report back as to what happens? (left hand side panel removed)
