vaillant ecotec 28e condensing firing problems

[bradchop]

HI guys, i have a vaillant ecotec 28e condensing heat only boiler which fires up nicely for about 3 seconds then cuts out. the error code comes up as f4 which is an ignition fault (lockout) went out when lit. i have checked the gas side of things and everything is all good, but im left with the electrode, ignition lead or electronic igniter!! :44:


has anyone else come across this problem and can save me going to the plumb center 3 times ??? :rockon2: lol


thanks guys n gals

update, i switched the boiler on again and it has started to work as it should!! very strange!! im not going to put on the boiler cover though just yet as im not that lucky!! i think it points more towards the electrode itself though..does anyone else agree?

clean both sides of electrode connections/rectifierer

thanks for your reply. update. i brought a new electrode. only 18 quid from plumb centre. so far so good. its been running for over 40 mins now so it must have done the job.

thanks all

RAK Random Acts of Kindness is the way forward
