Mira Essentials pilot valve replacement

The low pressure light is lit and there is a noise from the shower like a kettle coming to the boil but water is cold. Can you give me your opinion and remedy?

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 allows power through to the elements

Also check the inlet filter which is on top of the inlet connector.

Unfortunately the pilot valve for this shower is obsolete, however...........

This is the Pilot valve for the Sport which is still available

You can adapt it for the Essentials, you need to swap the white spindle that carries the knob with the one on your old valve.

Check where the notches are on the sport spindle, because when you refit the essentials spindle that you fit it in exactly the same position as the one you have removed.

 The pilot valve is a common fault

 

Turn off water and power

 

Put something in the waste just encase you drop a screw!

 

Remove cover

 

Remove splash plate at pipe entry

 

Remove 4 screws from 'U' clamps and 'U' clamps

 

Later models have “Torx” screws so you will need a “Torx” screwdriver with a T10 Bit.

 

Remove screw above letter 'A' on drawing

 

 

Ease pilot valve forward (if there is no movement on the pipe work you will have to disconnect it at the inlet connection take care to hold the brass body with pliers when slackening the nut)

 

Swap the wires over from one pilot valve to the other one by one

 

Then reassemble

 

Turn on water and allow the water to come thru unit before switching on power.
