My idl40 indesit dishwasher has stopped heating. With my dad's help we have changed the heating element, the thermostat, part of the pcb (the white/black box, something to do with a switch?), checked any circuits we can find and made sure everything that should be connected and plugged in is. But it still doesn't heat up! I know it was a cheap model but I would still rather fix it if possible cos can't afford to buy another at the mo! Any help will be greatly received!
