The pressure was down to 0.8 and I raised it but may have raised it too high to 1.9. This has resulted in the LCD display flashing and the heating turning on and off. When it is switched back on at the mains the heating comes on and stays on for 30-60 mins but cuts out at the pressure rises to 3.0. I have been told I need a new central heating boiler - could this be the case? Alternatively I have been informed I need to have a new PCB and exchangeer fitted at a cost of about £600.
my boiler pressure went down to .6 i raised it t0 1.4 its now comes and makes a noise for 2 mins then goes off for 5 mins and then makes the noise again this had continued for 2 days now. im worried something may burn out any ideas on what to do? many thanks
