Hi, I have a Riello RDB 2.2 BG1 BLU 26 burner installed in a Grant Vortex Blue Internal 26KW boiler. This morning we woke up to a relatively cold house as the burner was continuously going through a start cycle (pre-purge?). it didn't lock-out even after dozens of cycles. it did the same thing about a month ago and i simply powered it down for a few minutes whilst i had a look the photocell. The photocell was pretty spotless, gave it a wipe and re-installed it and the burner fired up first time. This morning I simply powered it down for a minute then switched back on and it fired up first time. The boiler is due a service in a couple of of months, are there any spares I could aquire in readiness for the engineers arrival? Thanks in advance.

Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
Riello burner continuously cycling but not firing

Well you could check/replace the photo cell I guess in the first instance but it could be lots of things. If the start cycle fails the boiler should lock out. Not happening here and if memory serves me I saw that exact scenario a few years back with the boiler start cycle endlessly repeating and it was the controller. Whatever I would guess a heating engineer would want to diagnose the fault him/herself and provide spares as required.
As above photocell first suspect
We have changed a few control boxes on that burner.
Let your engineer sort out what's needed some of blue flame burners need blast tube changing at fairly regular intervals.
Grant discontinued the blue flame boiler some time ago we have changed one or two problematic blue flame burners for the standard white flame .

Thanks Stuart981 and Exedon for taking the time, very grateful.
My boiler was installed in 2016 and although the guys didn't do a particularly grand job it's behaved pretty well up to now. I am wondering if I should just bite the bullet have a new burner fitted, maybe one of the white flame ones you mention, and not have to worry about the potential costs of diagnosing hours and parts as none of that comes cheap? Any advice gratefully received.
