Hi all,
Just wondering before we throw more money at this boiler if anyone has seen this issue before. I already know that F.28 is failure to ignite, and I have witnessed this happen a couple of times now. Note that this *only* happens when the boiler has not been used for several hours and it is cold..
When heating or hot water is called, the boiler fan & pump comes on as normal, I hear the click of the gas valve and can see the igniter sparking through the peep hole with the outer casing removed. The boiler attempts to ignite three times for several seconds each time before the F.28 lock-out happens.
Usually when cold the boiler will ignite on the second or third attempt, but sometimes it fails and locks out on F.28 and will not strike up again until I reset it. Once the boiler does eventually ignite from cold, it goes with quite a 'woosh'! Once the boiler has warmed up a bit, it'll run happily all day long & will shut down & re-ignite without an issue.
We have recently had the entire central heating system re-plumbed which should not affect the gas side of things. We have already had the electrode & flame sensor replaced as the flame sensor was getting slow to react.
Yes I know I need a Gas Safe engineer out to it, but I'd like to know what to expect first. I don't want to throw too much money at this old-ish boiler ideally, but also cannot afford a new one right now!
