Neff Dishwasher S4443N6GB/01. Runs ok but doesnt heat the

This answer was rated:

Hi. Neff Dishwasher S4443N6GB/01. Runs ok but doesnt heat the water. Is there a way of checking whether it is the control module or the heater - without replacing them ?
JA: Are there any error codes or blinking lights on your Neff dishwasher? How old is it?
Customer: No error codes - about 17 years !
JA: How long has this been going on with your Neff dishwasher? What have you tried so far?
Customer: A few days. What is there to try - it has run several times, but obviously cold. Can access the control unit - no obvious problem but reluctant to try to access the heater. (presumably a nightmare job !)
JA: Anything else we should know to help you best?
Customer: Not that I can think of. I have done repairs (pump, I think) on a Bosch dishwasher years ago - but not on this one.)


Welcome to Justanswer … my name is ***** ***** I will help you today!

Can you test the heat pump with a multimeter ?

Have a multimeter - how difficult is it to access the heater ?

It is more likely the heater that is faulty then the control.

You can unplug it and pull it out.

Then remove the side and bottom panels.

Check this VIDEO to get an idea on how its done.

If you have any further questions, please do not hesitate to ask!
