I would recommend a RGI to inspect it. It could need the condensate trap and sump cleaned out, or it could be you need a new spark electrode as these 'warp' and the spark gap becomes too big and ignition may not always happen first time, letting a small gas build up occur.
older Isars have had a problem with the insulation panels falling onto the heat exchanger causing explosive ignition. a kit has been released by ideal to hold these panels in place. if the kit has been fitted, the heat exchanger might be marked with an orange dot, although i have heard that when the electrode kits have been replaced ideal engineers also denoted this with an orange dot on the heat exchanger, so best to get it checked out
gas4you, out of interest have you ever seen an ISAR that works ok? coz i havent

Yes I have seen loads, strangely enough. I have fitted around 100 of them and used to be an Ideal 'preferred installer' a few years back.
Luckily, most of the Isars I go to now are not the ones that I fitted and I do tend to tell people to call out Ideal for a fixed price repair.
Sadly though, to date, I would estimate that I have approx a 30% failure rate on the ones I fitted. A disgustingly high % rate
Compare that to the ATAGs that I now like to fit, where if this goes above 0.5%, ATAG panic and assume they have major problems, so Holland are informed and action is taken

maybe the black rubber seal top of the turret has come off
almost every new house i have been in has an Isar! is this because of ease of installation or because builders (particularly Wimpey) get the boiler for pennies? they are nice and compact and as with everything in life, theyre great when they work, but i miss the days when you could install an Apollo and it wouldnt go wrong for 15 years lol (not that ive ever installed an Apollo to be honest, but you know what i mean )

Out of interest at what % do Vaillant panic at?
I don't really know, perhaps DM can enlighten us
I am on about a 3% warranty call out rate at present. Most common are pumps internally leaking and 3 pumps that have stuck/failed.
Very, very few of the F75 faults though
