I have a problem with a Megaflow Direct Immersion Heater and Thermostat shorting.
When the immersion heater is switched on, its shorts with the thermostat and there is a bang/flash and the fuse blows.
I thought it was a faulty TSE thermostat but having replaced the old thermostat with a new one, the problem still happens.
The short appears about 3cm from the head of the thermostat (see photo)
I have checked the resistance of the immersion heater and it is around 18 ohms, which appears to be correct.
Any ideas anyone can give would be much appreciated.
