Cable Forum - View Single Post - Immersion heater keeps tripping the fuse box

The switch is likely to be the immersion heater. Just follow the flexible cable that emerges from the heater cover and it should go back to the switch.

If it trips the leakage breaker (Master switch) then the heater element or possibly the thermostat is likely to be faulty. (Short circuit to earth)

An electrician can verify which part is faulty. The thermostat is easy to change as it fits inside the element in a sheath. If the element needs changing then it is necessary to drain the hot water system. Both parts are relatively in-expensive.

This happened a few years ago in my mothers house and it turned out to be a fleck of rust shorting a connection under the cover. Worth a look.
