Hi, I have a Hotpoint DWF30 dishwasher which is not heating

This answer was rated:

Hi, I have a Hotpoint DWF30 dishwasher which is not heating the water, I have changed the heating unit for a new one thinking that would be the first place to start, but this does not seem to have solved the problem. What is the next course of action in getting the water hot? Would it be the PCB?
Thanks in advance for your help

Did you test the element with a meter?
Was it open circuit?

If the element is not getting 240Volts the likely culprit is indeed the PCB.
Is there any error codes shown?

Thanks

Hi Rob, Thanks for getting back to me.
I have metered the old element and it shows continuity, so not open circuit, either way i have already fitted a new heating element, and it show 240 volts at the terminals, and also I get voltage at the thermostat so that looks good also.
There are no error codes as this machine I think does not have this function? I may be wrong but the machine start OK, but does take a while to complete a cycle, even to the point I ended the cycle I was running earlier today to test the element.

So what do you think? Relay? PCB?

Look forward to your reply, but I will be offline for a couple of hours now

Thanks Pip
Hi Pip

Sorry, this doesn't make much sense

If the heater is ok and there is 240v to it, it must heat up?

Are you using a meter or just a test lamp?

Thanks

Hi Rob,


 


I used a Kewtech KEW1700 Voltage Tester to check voltage at the terminals of the element, and to check continuity when not energised.


I got a reading of 230 volts, and I agree it should be getting hot as the element was energised, but no hot water.


 


A strange one I know which I why I suspected the thermostat but as this is part of the new heating unit and was also showing voltage it has me stumped.


 


So there is nothing else which could stop the element from working then on this machine?


 


I have turned the machine on again now and will run a wash cycle and see if it works, perhaps I shut it down too early yesterday before it got to the heating part of the program. I'll repeort back soon.


 


Thanks Pip

Hi Rob,


 


So have just got home and the machine went through it's quick wash low temp cycle, the plates etc were clean, but wet, this could be the low temp setting, so not drying fully.


Have now set it on it's high temp setting cycle, which will take an hour or so, will get back to you with the results, if any


 


thanks Pip

Well it all seems to be fine, hot cycle took a while, but it does I'm told, and it did get hot and the cutlery etc was dry when it came out so I think I have sussed it. Thanks for your help anyway, but me changing the heating unit seems to have done the trick

Hi Pip

Thats great news
