mira sport 9kwt

Hi, I have water and pressure but the low pressure light is continually on unless turned to low pressure setting. on the high setting the water will get hot but flow reduces probably more than you would expect and you have to turn the heat dial almost all the way round. Have cleaned the hose and water inlet filter. Any ideas thanks

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 cool it properly, it overheats the safety device cuts in (TCO) and turns the power off to the elements until it cools down and it all starts again!


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


The other possibility is a faulty flow/stabilizer valve not allowing the correct amount of water into the shower.


There is a link below that explains the above.

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.
