It may be afaulty element in the heating tank (there are two, three in most 10kw showers)you can check them with a multi meter you should have a reading of around12>18 ohms.

If you have power to the elements andno heat it's probably the elements, no power to the elements then it'sprobably a micro switch.

If you don’t have a multimeter  wesell them at around £10 each with a link to an on line guide on how to use them for checking and testing the various partsof your shower.

 

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

(so you know if they are dud ornot)  and lots of other jobs, in short they are well  worth the £10.

 Theother possibility  is the outlet ThermalCut Out this is a black disk with two wires going to it and it is mounted onthe out let pipe  (The bit between the heating tank and the hose)

Examine the connections closely if you see anydiscoloration / signs of overheating then the TCO needs replaced.
