If the shower is absolutely cold then I think you may have afaulty Thermal Cut Out

A faulty TCOwill have no continuity across the two terminals (The black thing on top of theheating tank)

Therefore agood TCO will have power at both connections and a faulty TCO will have powerat only one.

(Thefunction of the TCO is, if the water over heats it cuts the power off to theelements)

See Video.

Ifthere is some heat it may be a faulty element inthe heating tank (there are two, three in most 10kw showers) you can check themwith a multi meter you should have a reading of around 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 a multimeter we sell them at £10 each with a guide on how to use them for checking andtesting the various parts of your shower.

 

Apart from helping to fix yourshower, they are really useful for checking you have a power supply toappliances, for checking fuses, letting you know much power you have left inbatteries

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