mira vie 9.5kw electric shower

Firs of all regarding the water coming out of the bottom, it sounds like the pressure relief device has activated.

The link below shows the tank outlet and the red ball which is the PRD,

The red ball has pushed out through the hole in the tank outlet, unfortunately this part is obsolete, however you can get the ball by buying the part below pushing the red ball out and using it in your shower.

Reguarding your shower going hot and cold see the checks below.


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.
