It was in the straight section of speedfit with the 2 Tees to vent and feed. TBH I was so pleased to find any blockage I didn't check precisely, but I'm pretty sure it was at the feed T, so after the vent. PP2 15w, PP3 28w with HW and CH on

Sorry to be slow.. lots other stuff to deal with, but.. RESULT! Took a while to bleed air from system but now running nicely both CH and HW. Initially pump only using 7w on CC3 as before but after some gurgling etc it's now 40w on CC2. I guess I'll switch to PP2 once it's settled. I'll need to...

Ok some progress. I've drained down just enough to clear the section of speedfit which includes vent and inlet. I then removed the speedfit section completely. The 15mm feed was fairly clear, but the 22mm straight section was quite blocked... maybe 5mm diameter. To my mind this could account...

OK all pretty hot at moment so will need to wait a while before doing anything. I dont recall doing or seeing any isolation on feed, and tank drained OK on last drain down so feed should be clear. That said, in effort to clear airlock I backfilled and there was very little flow up into tank...

ok with outlet closed briefly, power goes to 24w and can hear flow restriction in valve

when you say useless, you mean not correct? so low reading imply airlock rather than blockage? Alos just realised I dont have large enough spanner for pump nuts - only a DIY guy!

Just done watts - they fluctuate slightly but only by about 1w: with CH and HW on CC1 5w, CC2 6w, CC3 7w PP1 3w, PP2 3w, PP3 4w CP1 2w CP2 4w, CP3 5w with CH only the figures are the same, with HW only the figures are about 2w lower in CC, and about 1w higher in CP mode

So isolate pump both sides, undo joint on outlet just enough to be sure water in there? Sorry if sounding dim!

You mean break the pump inlet without draining?? Also I've got x400 I'm trying to get in there so will probably need to drain a bit. What's best way to ensure x400 gets into system rather than sits in FE tank? Also today on firing up system hot water has definitely got round a bit further and...

Thanks for that. The valves were replaced but far as I know no check was done for flow. As mentioned before, the last metre leading to pump including vent and feed are speedfit so it would have been easy to demount and check this section. I'll check wattage in a bit. Slow start today, other...

Thanks for that. TBH it's exactly as it was yesterday before replacing parts. Pump orientation has been checked. Coil is Def plumbed bottom to top. So, wattage may suggest still airlock? But when I connected to mains to backfill there was minimal flow into FE tank. Maybe FE is blocked which is...

When I say no flow, I mean rads and hot water not getting hot. There is very slow flow, and bathroom rad got hot after over an hour but no others. Cylinder loop slowly gets hit at bottom but still cool at top. I think it's been set just on CC3. At one point it was displaying numerics.. . I think...

OK thats interesting. TBH I'm done for the day - bizarrely I've also been trying to sort my daughter's heating issues and looks like she needs a new boiler. A frustrating and damn expensive day. I'll take a look tomorrow - is it bluetooth type hookup?
