Hello

Boiler has lost pressure 2 days running.

Have had a closer look at the repressurising taps and the one on the left looks like it isnt able to close off properly. Fault is F22.

Is this the likely problem?

What does the boilers pressure rise to when heating is in use ?
A filling loop that doesn't close would cause the pressure to increase .
The pressure loss is likely to be unrelated.
 
Thanks, I've just found the problem and good job I was using a cordless hoover. Carpet near radiator was sacturated in water. Leaking radiator! Thankfully easy fix, hopefully.
