The replacement capacitor arrived this morning. Turned mains supply off (& verified), removed WR1 (SCR) unit from the wall managed to prise the clips holding it together apart (without breaking any) de-soldered the old cap and re-soldered the new. Re clipped everything back together, put WR1...

Ahhh.... Noted! Dave

Thanks Bernard. Aware of this but thanks anyway. I have a solder sucker (I really need to get out more and meet people). Dave

Thanks Ian That looks simple enough. As long as I turn the 240V mains supply off it should be okay. I've sourced a suitable capacitor from ebay and should have it delivered in a couple of day's time. XRD

The red 'Receive/Alarm' light on the SCR flashes periodically for around 5 seconds every five minutes or so (which means that the Digistat and SCR are communicating) and the green light is 'on'. This means that we should be getting heat. However, the zone valve doesn't actuate, the boiler...

@JobAndKnock, First of all my apologies for incorrectly attributing the original comment about Zinsser B.I.N. to you. For some reason, I seem to have overlooked @Canyer ‘s post. Secondly my thanks for a very comprehensive reply and very kind of you to take the time to write that. The fault...

Thanks J&K. However, it still doesn't answer the question I asked yesterday - namely "Would either of these be any use to overpaint the existing undercaoted sills or is it still a 'strip back to the wood' job?" I don't understand the need to strip back to bare IF this stuff seals the wood...

Bump Anyone??

Hi, We had avery similar issue - albeit on a System Boiler not Combi. Seems that during the long down-time (our CH system had not been used since March) there had been a build-up of gas in the pipes/radiators preventing the water from circulating properly. We could get both hot water and...

Seems like we have a solution. It seems that during the long down-time of the system, corrosion produced hydrogen causing "air" pockets such that the water level was too low to be pumped around all 3 floors (basement & main living floor, Zone 1 - and the top floor, Zone 2). Hence the bottom...

Yep, it is a reddish-brown colour. Pics to follow later today. Update: Pictures These show the sills (or should it be cills?) after my daughter has ovepainted the wood with two coats of undercoat. Would either of these be any use to overpaint the existing undercaoted sills or is it...

Thanks for the replies. To clarify, the window sill is in a conservatory, not a kitchen or other room. Not sure whether it is softwood - the answer is possibly *shrugs* Can't see much evidence of knots however ... XRD

Strange title, I know. Here's the thing, my daughter has just painted a stained wooden window sill. She's given it two coats of undercoat but something is bleeding through and I'm wondering what we can do to stop it - she wants to gloss paint the windowsills. I know for knots there is a...

Hi Chris, Yes, Zone 1 (basement and main floor) works as normal (rads get toasty hot) even when the boiler says LoPr 0.6 for example None of the old system was kept. The Ideal Minimiser installed by British Gas in 1997 had a header tank in the loft but when that was replaced around 2010/2011...

Sunday morning, 07:30. Turned on floor 2 heating (thermostst set to 23C and programmer/timer on). Checked boiler - LoPr 0.6. No evidence of water ANYWHERE. Pressure topped up to 1.2 bar. Bathroom started off at 17.7C and rose, albeit reluctantly, to 18.4C in half an hour. Radiator under...

Hi Chris, There is a motorised valve for the heating right next to the hot water tank which. In the past it clicks and the whirrs shut (?) but I don’t know if it is a 2-way valve or 3-way. As far as I can remember, BG back in ‘97 only fitted one motorised valve. There aren’t any on floor 1 for...

Some additional pix and info .. ^ ^ The floor underneath the boiler (the darker red area is damp but not wet) ^ ^ Easier to see in 'real life'. ^ ^ The 2965 Error ^ ^ ^ ^ Pipework under the boiler after insulation rmoved ^ ^ Note the drop of water at the bottom of the white...

An update. I just wondered what would happen if I turned off the call for heat for floor 2 (reduced thermostat from 26C to 14C) and increased the thermostat for floors 0 and 1 - depite the boiler saying '2965'. Boiler started up and after the reported temperature dropped steadily until about...

Okay - an update. Been out of the house all afternoon from mid-day and just got in at 7pm. Went down to see what the boiler is saying - LoPr 0.5 bar There a few drops of water on a pipe underneath the boiler, but looking upwards at the 'innards' there's no sign of any water. Anyhow - to the...

Trying to post some pictures - but the have to be on a picture-hosting site - such as Flickr or imgur? You can’t upload direct from your pc? If so, I’ll have to upload them first. XRD
