not as hot as it was

ok guys back again i have tested the thermal cut out it reads 0000 ohms so does that mean it is ok with the power off and flow seems good dribble at high temp and powerful at low .just had to change the pressure relief washer as it was leaking out bottom but when i turned it on my daughter had it turned up high so not sure what went first ..on my model 4-5 light and it was hot now its up at 8-9 lights then you start to lose pressure and our cold taps have loads of pressure . so do you think both things are connected it is old had it at least 12 years changed the solenoid last year also any get back to me and let me know what you think and thanks for all the help

Hi Again

The Thermal Cut Out is a switch so it is either on or off it doesn't have resistance if it has continuity then it is working if it doesn't then it is faulty

I think you may have a faulty Thermal Cut Out

A faulty TCO will have no continuity across the two terminals (The black thing on top of the heating tank)

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

(The function of the TCO is, if the water over heats it cuts the power off to the elements)

See Video.

However I think your problem may be with the elements see below for video.


It may be a faulty 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 around 12>18 ohms.

If you have power to the elements and no heat it's probably the elements, no power to the elements then it'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 and testing the various parts of your shower.


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

(so you know if they are dud or not) and lots of other jobs, in short they are well worth the money.
