Creda Aquawave Electric Shower
A faulty TCO will have no continuity across the two terminals (The black thing on top of the heating tank)
Therefore a good TCO will have power at both connections and a faulty TCO will have power at only one.
(The function of the TCO is, if the water over heats it cuts the power off to the elements until the water cools, this can take up to 15mins)

After fitting a new TCO
When fitting a new TCO listen to the shower, after it has completed its first on/off cycle, if when it is switched off you hear it continuing to heat (Noise like a kettle starting to boil) this will mean that there is a switch or a relay that is stuck in the on position, this is keeping an element energised and this is probably what caused the original TCO to fail.
If this is the case replace the faulty switch or relay and make sure that you switch the shower off at the isolating switch when the shower is not in use because this may cause the new TCO to fail.

I have replaced the TCO on this shower but it still does not work. I attach below the results in a truth table.
I look forward to hearing from you.

Unable to send truth table.
, if when it is switched off you hear it continuing to heat (Noise like a kettle starting to boil) this will mean that there is a switch or a relay that is stuck in the on position, this is keeping an element energised - this is what is happening. How do I know which switch or relay I need to replace?
