Beko DW603 I’ve replaced both the heating element and the thermostat with new parts. It’s still not heating. Looking online I’ve not been able to find what else could be causing the problem and what else I can do ? Thanks
You need to continue troubleshooting the problem.
If the dishwasher still has power, and assuming that the parts you used for the replacements are actually functional and not defective, and assuming that they were installed correctly, then the issue has been narrowed down to be between the replaced parts and the incoming power.
the relay that provides power for the heating element is usually on the PCB very often they are “ ice cube “ or smaller in size normally black plastic, or white plastic on consumer electronics. Rarely they are clear but sometimes , when the washer tries to heat the water or dry there should be 120v or 240v depending on your location. Normally you can feel the relay click most are still mechanical, it is possible that it is solid state then there will be no click but the output voltage to the thermostat should be there if not the relay is bad and many times the relay fails if there is a problem with an element or just an old system the contacts get pitted and fail to make complete the circuit.
