I have the galaxy aqua 4000si and it has just stopped working.
There is power to the shower, but no lights on, there is also approx. 3.8 ohms at the solenoid.
I have two of these shower units and I have swapped the circuit boards about and that is not the problem, as the one which works still doesn't work on the broken shower unit. Help Please
It is possible the TCO is at fault (it sits on top of the Heat Can) you should have a positive continuity test with the power off, also double check the pull cord or isolation switch teminals
