Hello All,
I would be grateful for your thoughts on a problem with my Greenstar 24Ri running a vented system with HW Cylinder, CH and UFH.
Since approx April the CH & UFH have been off with HW timed for early morning / evening daily.
In mid-August, we awoke to no HW and boiler was flashing its blue light. User Manual advised performing the reset procedure. Boiler fired up and all seemed well.
From approx end-Aug to end-Sep, these boiler resets were required more frequently. I tried all combinations and order of demand of HW/CH/UFH but could find no pattern. I also checked F&E tank which was at normal level with ball cock working, and tried to bleed all rads (small amount of air in one in bathroom).
Eventually, the reset did not work and boiler would not fire. I looked up the installation manual online and discovered the exact fault code (long off, flash on) which said it was an Ignition Lockout.
I have home emergency cover which covers loss of HW/CH so I called them. They initially diagnosed a new PCB required and replaced it. This made no difference.
A new engineer was sent out who checked the flame rectification device and found it dirty/corroded. He cleaned it up and voila the boiler was seemingly back to normal. He came back after 2 days to replace the part entirely. Boiler was working and 2-weeks went by without a hitch during which time I set CH and UFH to come on as weather turned colder. All seemed good.
On Wed last week, we awoke to boiler flashing same error code. Engineer diagnosed a faulty gas valve which was replaced today. Now, boiler will fire after reset, but it lasts only 2-4 mins and dies. It tries its 5 attempts to relight before giving up with flashing blue light. Exactly same flash (long off, flash on).
The engineer was at a loss and suggested that the HEX might have a blockage. I pointed out that the error code for a HEX problem (blockage, overheat etc) was different (long on, flash off) as per the install manual. He could not explain and could not investigate without authorisation due to potential cost of work/parts.
I would be very grateful for any views from the forum as to what the problem might be given the scenario above. Also It would be great if anyone with experience of this boiler family has ever known it mis-report an error code (I.e. Report an ignition related problem when it really is an overheat or HEX issue).
Many Thanks!
