Triton Bezique II tripping

Hi. My Bezique II keeps jumping from highest heat setting (the button with 2 red lines) to lower settings (middle button, 1 red line, or bottom, blue line) by itself. It's not low pressure. The power light flashes when it's about to happen and there's green flashing (arcing?) on this PCB when it happens. It's intermittent but frequency is increasing. Does it sound like PCB's faulty or could this just be a symptom of another problem? Would appreciate guidance, please!

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 the pcb will then try to reduce the temperatureby switching off an element.

If the valves are OK then itis likely to be a PCB fault.
