Hi Helen: Has your partner checked to make sure the element is connected properly ? Does your partner have a Multimeter & know how to use it for continuity testing ? If so then the first thing to do would be check the continuity of the new element to make sure it’s not just a matter of a faulty new element (Not unheard of).
Sorry for late reply. Took heater back to supplier today,supplier tested it said it was ok but replaced anyway to keep me happy .fault still same.:-( Machine was stopping with I think it was prewash light flashing,fault guide said heater fault
OK: With the machine OFF & UNPLUGGED, he needs to check the continuity of the wiring from the heater back to the control board & check any thermostats as well.
