After fitting a new TCO

Whenfitting a new TCO listen to the shower, after it has completed its first on/offcycle, if when it is switched off you hear it continuing to heat (Noise like akettle starting to boil) this will mean that there is a switch or a relay thatis stuck in the on position, this is keeping an element energised and this isprobably what caused the original TCO to fail.

If thisis the case replace the faulty switch or relay and make sure that you switch theshower off at the isolating switch when the shower is not in use because thismay cause the new TCO to fail.
