A: First check that all the cable connections are fully pressedhome.
Then check the solenoid valve
It may be your solenoid valve, you can check it if you havea multi meter, you should have a reading of at least k3.5 ohms, across the twoterminals any less and you need a new valve. (Check the valve in the failedstate.) (When it has stopped working!)
If there is power getting to the solenoid and it is notoperating then there is a good chance that you have a faulty solenoid.

The videois 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 checkingand testing the various parts of your shower.
Apart from helping to fix your shower, they are reallyuseful for checking you have a power supply to appliances, for checking fusesand letting you know much power you have left in batteries
(So you will know if they are good or not) and lots of otherjobs, in short they are well worth a few pounds

If the solenoid is OK when switched on is power getting tothe pump? If as you say there is power getting to the unit and no power goingto the pump then that would suggest that the pump PCB is faulty.
