Hotpoint NSWR 742U - Water Not Heating
Hotpoint NSWR 742U just over 2 years old. Ran a cycle for some very dirty cotton sheets at 90c recently, completed successfully.
But since then the machine refuses to heat the water on any cycle. No error code.
During the phase of the cycle where the water would normally be heating, the machine is making a clicking sound ( a bit like a clock).
And before anyone says that you can't tell by touching the glass window if the water is heating, believe me you can. And it's stone cold.
Any ideas? Thanks.

I would check the heating element with a continuity test meter. It might have not liked the extra work it had to do on the 90 degree cycle and decided to die. Obviously this wouldn’t happen to a healthy heater but if it was in poor condition or caked in limescale it’s possible.
Also check the wires to the heater.

On a washing machine heating element it’s unlikely Andy. On the element the toc is designed to trip if the heater ever came on with no water in the drum. Unless there was no water in the drum I’d say it was not possible for the heater to get so hot that it tripped the built in toc.

do you hear much of thermal cut outs giving trouble on machines Andy?
Yes it could be the heater relay not staying on. That would need a new pcb. But need to check the basics first.

the Clicking sound - could that be a relay clicking on the main board (or electronic board behind the fascia control panel) for the heater circuit?
also could check the thermal cut-out (should be in the middle of the heater element terminals) se if thats enacted due to overheating - will need replacing if no continuity there
