Faulty TCO in Mira Sprint?

Okay I've replaced this unit a number of times now. When new unit goes in it works straight away. Had this one in a month or so. Water has gone cold. No continuity across TCO. If I take TCO out and then reposition it does this reset the TCO? I get continuity again when I do this but then shower temperature fluctuates for a bit then runs cold. Again no continuity across TCO. Frustrated!!

There is a reason for the TCO`s to keep failing.

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.
