I have an intermittent fault on my boiler. When I turn the hot water tap on the boiler fires up as expected but within a few seconds there is a loud noise, the pressure guage shoots up and fluctuates rapidly around 2-2.5 bar and the burner (and yellow light) goes out.
I press the reset button and it restarts and then works fine.
I checked the cap on the automatic air bleed and it was closed tight. When I unscrewed it a short chuff of air came out but unfortunatly the boiler still has the fault.
I have also pumped the accumulator up to .75 bar but to no avail.
Can any one help?
