To reset your safety switch after it has tripped, first unplug all appliances from their power points. Flick the safety switch, and then plug each appliance in one at a time, making sure the circuit remains on. The appliance which trips the safety switch will be the faulty appliance,and should be isolated to restore the power.
Firstly, check that there are no leaks in the system or water is not automatically filling in the tank. If this is ok, then it’s likely that the thermostat or the element needs replacing, so call us to take care of it for you.
If your fan is working on one speed only, and almost stops on the other speeds, the likely problem is with the capacitor in the fan controller or motor. Check if it is more economical to replace rather than repair.
