OK so it's not the thermostat. In fact I think the thermostat is the only thing that's working OK.
The immersion heater is dead... and I suspect that sometime this morning as the wornout copper finally ruptured allowing water and electricity mixed there was a tiny "CRACK!" as the timer got taken out by the death throws of the heater.
At least I know what's wrong and what needs replacing, the timer and the heater. Timer easy, heater easy if it comes out of the tank OK. Sprayed it with WD40 and scratched of all the corrosion tonight, hopfully that'll help.
I bet geodhinn will be amused I'm blogging what must be an extreamly basic job for him.
