Sorry, Mia - at this point it's become clear that you are not going to be able to diagnose and fix the problem yourself. And that's nothing to do with being a housewife - a man who didn't know what a multimeter was would be just as stuck. Only less likely to admit it.
So it's repairman time, or back to Fairy Liquid...
He needs to disconnect the heating element and check it's resistance and IR.
As he would with an immersion heater.
Also, as with an immersion heater it could be the thermostat or anywhere in the wiring.
As he's an electrician I hope he has more than a multimeter.
