I have been to an Ideal isar HE 24 which is banging and locking out. I listened to continuous run of fault from customer about this boiler which was from wormfront. I am familiar with the isar and some of the problems but this one has got me stumped, any HTG engineers advice greatly appreciated. Now to the story, Firstly tested boiler on dhw preheat, worked ok, ran the dhw and boiler started to bang after a short time, ran boiler on htg and againe boiler stared to bang.
Noticed spiro fiter on the flow from the boiler which made me think there could be a blockage. First of all I checked the pump it was running took it off and check pump impeller all looked ok. I then took filter from flow washed it out and fitted it in the return, well boiler drained I flushed boiler back through the flow and return with diverter valve and pump on and off, as far as I can see it all seem clear, I also changed boiler flow thermister and it still bangs.
Engineers please HELP ME this one seams to have be beat.
