Protherm 80ec Boiler Water Pressure

[Sull]

Plumber has replaced water pressure sensor, PCB, cleaned valves etc. Still the water pressure bar is only rising to approx 0.9 when the boiler is full when heating on at 85. If drops below 0.6 error F0 and cuts out.
Any one experienced water pressure problems and resolved it.

Probably low mains water pressure!

Why is your plumber unable to advise you of what to do or to measure the mains?

Is he a right nupty?

May be better to get a boiler engineer.

Hi I probably haven't explained it very well.

Our water pressure is fine round the house and the boiler is full of water however the display is not showing the correct water pressure level even though sensor & pcb board have been replaced, valves have been cleaned etc.

He is a boiler engineer and has been in contact with the manufacturers but they keep saying replace this and that!

Any idea's for things that we haven't tried?
