Oil Heatslave 20/25 oil fired combi boiler has intermittent fault. Burner lock out keeps tripping,It will reset and run for a couple of days, but eventually will start to act up again and cut out, usually when first starting up The solenoid has been changed, the photocell and the Satronic control box. Overheat thermostat is not tripping , the manual reset does not need to be pressed, so it does not seem to be the boiler high limit thermostat, which leaves either the CH control thermostat or the DHC thermostat. Problem seems to be worse when first firing up the CH system, but has also ocurred when using the DHC, so not possible to trace to pin point to either of the possible culprits. Any ideas gratefully received[/i]
