There isnt a replaceable fuse, it has a thermal fuse which will cut out and reset itself as part of the PCB.
With these faults the majority of the time its the heating element at fault, you can test this by removing the back panel and checking your getting voltage across the terminals on a hot wash (after it completes the pre-wash). If your not getting voltage the next this to check is the NTC (thermostat) which sits in the middle of the element and looks like a bullet, check you have continuity across that.
Finally if the NTC is open circuit and your still not getting power to the element this suggests the main PCB has failed, at which point it would not be an economical repair as the PCB would be in excess of £100.
Please let me know if I can be of any further assistance.
Whats the model number of your appliance (should be on the inside of the washer door)?
The fact you have shown the NTC and element are not open circuit this does point towards a faulty relay on the PCB, its worth checking the wiring loom, but 95% sure its the PCB.
Do you require any further assistance?
I havent heard from you can you confirm the issue is now resolved?
