Electric Shower no water flow

[Oak Bloke]

I have just installed an Triton Ivory II Electric Shower 9.5KW as a straight swap for a Triton Bermuda 9.5 KW. There is is no water flow from the outlet and I'm completely stumped. Having installed it I returned it to the shop and replaced it thinking that there was a fault with it. I have ensured there are no airlocks or blockages in the mains water pipe and no blockage to the plastic inlet. It appears that for some reason the Solenoid Valve is not allowing water to proceed to fill the can despite following exactly the commissioning procedure in the Installation Guide. One other thing when I turn on the isolating switch the power light on the shower goes on but when I switch the power selector from stop to cold the light goes off and nothing happens. Any advice?

I think either the selector switch is faulty or has been wired wrongly. Did you disconnect any wires from it during installation?

In case it helps, mine is a triton Monaco, (just been and checked), and the power light on the shower only comes on when the elector switch is set to hot, ie one red and one blue, or both reds. When the selector is set to off or cold, the light is off.

I would get a circuit tester and test for anything coming out of the selector switch, and I'm prepared to bet my mortgage that no power is reaching the solenoid valve.

Thanks. No wires were disconnected during installation. I have tested the solenoid valve and there is power reaching it. My tester shows power on both the brown and blue connections even when the selector is switched to stop. This does not seem right. This seems to be the case throughout the appliance! Any thoughts?

A knackered isolator switch or a loose connection in the switch or CU.

Oak Bloke,

The symtems you describe are consistent with a loss of the netural connection somewhere in the circuit.

check all connections at shower, double pole switch, rcd, YOU have got one??, and in the CU itsself.

When you check the voltage always check between phase & netural, not phase & earth as you are doing at the moment.

ALWAYS SWITCH OFF THE POWER before YOU POKE YOU FINGER INTO LIVE TERMINALS.

You did turn the water back on after plumbing in I take it?

Had Elecrtician round this morning. The verdict a knackered isolation switch. Thanks for all your helpful suggestions. Shower now working.
