In recent weeks my Baxi 35/80 gas boiler has started flashing for Fault on Pump or Low Pressure error. Turning the boiler off and on usually (but not always) fixes it, but the error will come again after a few hours. The pressure was at 2 bar when the error appeared this evening. I have attached photo showing the red light for the error. Is this a common issue that any boiler technician should be able to fix? (Last time I had a boiler issue (different issue) the first technician said there's nothing he could do). Thanks.

Another issue is the capacitor in your pump is on the way out.
