Zanussi zdf601s dishwasher is not heating water. I have checked the control panel which appears ok, no burn marks etc and heater element reads 25 ohms which i believe is ok too? Are there any other causes that would stop the water heating up on these machines? thanks..

bad solder joins on the pcb heater relay.resolder them then retest.If that don't work pressure switch or a blockage in the pressure hoses/pipework
