Keston C40 ignition problem code E02


My Keston C40 boiler permanently fails to ignite. It shows E02 error. Has anyone an idea what does it mean? Will simple restarting help? Or I should call the service straightaway?



Hi George

There are several parts which failure can cause E02 error: blocked condensate,the gas valve, high voltage cable, ignition & flame detection electrode, PCB or soothed burner. In your position I would try restarting myself, in many cases it would help to solve the issue- at last temporarily. If problem persists call service- to many parts to replace if you don’t have proper qualifications.
