Mira Advance ATL replacing thermostat

My shower heats up and then runs cold, my electrician suggested it may be the theromstat but which part needs to be replaced in order to replace the thermostat?

There is no thermostat in the shower as such there only thermistorswhich feed temperature information back to the PCB.

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 open / close the safety device that allowspower through to the elements.

 Makesure that the shower head is clean and clear, that the hose isn’t kinked (thiscan happen just behind the hand set where it is difficult to see) also checkthe inside of the hose although it can look OK on the outside it could havecollapsed internally

Onceyou have checked the above if the shower is still not working properly can youcheck to see if any of the warning lights on the front cover are coming on.
