Cent/heating & H/W or H/W selected at boiler.First thing in morning no hot water,30o light flashing,lock out.Leave tap running.turn switch to re-set,sometimes it fires first time,usually 3 or 4 times to get it going.temp.
L.E.D's light up to 70o no problem.Switch off tap and L.E.D's start going out over time,60,50,40. If the tap is switched back on at any of these Temps.boiler will light.If it goes to 30o light is on but not flashing,as soon
as tap is turned on light starts flashing-lock out and this goes on all day,
continually re-setting.No problem if the heating is switched on,everything seems to work ok.This has gradually got worse over the last 3 months
starting with once a week, to now, all the time.Have had the PCB out and it looks fine.My Corgi plumber who fitted the system 31/2yrs ago is stumped but i must admit he is more of an installer than a boiler repair man.Up until this winter the boiler has worked perfectly.Has anyone come across this problem or are there any suggestions.Ihave looked on loads of sites but can't see any problems like this.Hoping Potterton man or you other experts can help. Thanks
