Low pressure

I am not sure what you mean by cut out?

If you have no water then.

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 power is cutting off then

It maybe a faulty element in the heating tank (there are two, three in most 10kwshowers) you can check them with a multi meter you should have a reading ofaround 12>18 ohms.

If you have power to the elementsand no heat it's probably the elements, no power to the elements thenit's probably a micro switch.

If you don’t have amultimeter  we sell them at £10 each with a guide on how to use them forchecking and testing the various parts of your shower.

If the shower continues to work but you lose heat then

The things to check first are.

1 That the main valve coming into your house is fully open.

2 Then check that the valve on the line to the shower is fully open.

If these valves are not fully open then there may not be enough water
getting to your shower to open / close the safety device that allowspower through to the elements

Make sure that the shower headis clean and clear, that the hose isn’t kinked (this can happen just behind thehand set where it is difficult to see) also check the inside of the hosealthough it can look OK on the outside it could have collapsed internally
