Triton Opal shower buzzing and scolding on one setting

We have a Triton Opal electric shower that has three temperature setting selector buttons on the fron and a thermostat control knob beneath them.

The top button is the highest pressure selector with two red bars above it. Beneath this is the cold selector and beneath that is the lower pressure selector with one red bar above it.

Above all these are the low pressure warning light and the power on/off light.

The thermostat control is at the bottom with the hottest setting being if you turn the knob fully in a clockwise direction and the coolest setting is turned fully anticlockwise.



When we select the button with two red bars the water is scolding but with good pressure. It's as if we have turned the thermostat knob fully clockwise but in actual fact it is turned fully anti-clockwise to the coolest setting fo rthe two red bar button. It only does this when the two red bar button is selected and we get a buzzing noise as well from the shower unit.

The cold and one red bar buttons work fine.

Can you help please?

The things to check firstare:

1 That the main valve cominginto your house is fully open.

2 Then check that the valve on the line to the shower isfully open.

If these valvesare not fully open then there may not be enough water getting to your shower.

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

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

A rough check is to remove theshower head turn temperature control to fully hot the water coming out of thehose should be a bit more than a dribble then turn to fully cold and it shouldbe coming out at full flow.

Ifthere is not much difference between the two then you could have a faulty flowvalve.
