No water coming from shower

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

I notice you said that you replaced the solenoid recentlyhowever can you check it.

Is there something leaking inside the unit?

The reason I ask this is it is unusual for the switch torust also if there is any dampness about this will shorten the life of thesolenoid.
