I have a potterton prima F 50 boiler. When either the central heating or hot water come on via timer or 1Hr button, the pilot light comes on but the main burners fail to ignite. The fan is working is working. Thie is intermittent problem in that some days the boiler might work ok, but generally it fails.
The pump is working ok, the mid 3 way valve has been replaced, and the Main burner solenoid in the boiler has also been replaced, by the heating eng.
Sometimes pressing the (pilot)button underneath the bioler ignites the main burners. Agin either main burner stay ignited or go off.
Help ?
