This question is regarding Mira Elite ST - Shower Spares

faulty element or microswitch?

Have to set to high and almost to max Temp. Runs fine for 3 or 4 minutes and then suddenly gets very hot and tco activates. It will stay going hot and cold indefinitely every few seconds until turned off and on again and then fine for 3 or 4 more minutes. No low flow light showing, head hose and filter are all fine. Runs fine on medium but not hot enough for a shower even in Summer

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 the overheat safety device will turn the power off until it cools Then it all starts again





The other possibility is a faulty flow/stabilizer valve not allowing the correct amount of water into the shower.
A rough check is to remove the shower head turn temperature control to fully hot the water coming out of the hose should be a bit more than a dribble then turn to fully cold and it should be coming out at full flow.

If there is not much difference between the two then you could have a faulty flow valve.

Carry out this check after you check the inlet valves.
