No lights on but power at the shower

We Have 4 of these at our football club. All 4 are dead no lights on when we try and switch them on. Checked the breaker and isolator 240v there. Took the cover off 240v at the shower itself. Won't turn on at all on any setting. Unusual that all 4 would stop at the same time with the same fault. Any ideas?

It is doubtful that all showers stopped at the same time and have the same fault.

Did you check the power into the showers with a meter?

If so I would get an electrician in given the circumstances.

Hi yes we had an electrician check the supply to the showers. All had 240v on the incoming and out going side.

It may be your solenoid valve, you can check it if you have a multi meter, you should have a reading of at least k3.5 ohms, across the two terminals any less and you need a new valve. (Check the valve in the failed state.) (When it has stopped working!)

If there is power getting to the solenoid and it is not operating then there is a good chance that you have a faulty solenoid.

The video is intended as a guide and does not cover every shower.

If you don’t have a multimeter we sell them with a guide on how to use them for checking and testing the various parts of your shower.

Apart from helping to fix your shower, they are really useful for checking you have a power supply to appliances, for checking fuses and letting you know much power you have left in batteries

(So you will know if they are good or not) and lots of other jobs, in short they are well worth a few pounds

If these are ok then you may have faulty PCB`s.
