Looking for advice prior to calling engineer. The above boiler has been leaking for some time out of the overflow, so had a quick look today. The PRV seems to be working fine. When I turn on the radiators the pressure starts to climb pretty steady, and above 3 bar, when eventually the PRV...

So the CC door seal had partially disintegrated, on the top left side. Looked ok, but crumbled when touched. Engineer fitted a new seal, cleaned & hoovered the burner & HE fins etc. Seems to be working fine now, so fingers crossed. Outstanding diagnosis by Ianmcd thanks. Really appreciate you...

FAO Ianmcd or anyone else that may have an opinion. In case door seal/PCB swap doesnt work & giving this more thought: As this only happens with CH, is it feasible the pump might be defective or nor operating efficiently? I ask this as the HW is a relatively small circuit, whilst the CH has a...

PS; more for my own information, the CH runs consistently for around 15 minutes, before tripping on overheat. I've turned down the boiler main thermostat as well, but it doesnt make any difference. No idea why it will run 15 or so minutes before tripping out?

Ah, I see, ok, thanks for explanation. Cheers

Cheers, struggling with why it could cause overheat trip Ian..

So an update as promised, engineer was in today and replaced the flow and fan thermostat, and the flow thermistor. Thought it had sorted it, however the boiler again tripped out on over-heat, He also checked wiring. He's returning with a combustion chamber door seal kit, but I'm not sure why...

I will, and thanks for info. Much appreciated.

Hi, yes the fault sequence on the 3 front LED's are On-Off-Flash which is overheat fault according to the fault indication info panel? Weird I know As you've said above, the fault finding diagram say check stat for continuity, then check connectors, then check thermostat, then chamber door...

Hi, yes, if HW is on and I switch on CH it locks out in overheat in 5-10 minutes. HW on it's own is ok. CH on it's own works initially for 5-10 minutes then locks out. Funnily, after the initial lock out, once its reset it seems to work fine? Also checked pump and it's fine. Water seems to be...

Anyone, please?

*disclaimer* before anyone mentions it, a Potterton engineer will be getting called out. So the problem; Occasionally the boiler was locking out, with the fault code indicating overheat. Takes around 10-15 minutes to reset the boiler. It usually only happens once, & after reset, works fine...

My thermal was no use, too close. I'd need to be few hundred yards away. Pipes under the floor were just a huge heat plume.

Yes, can see pretty good animal heat signatures to well over 1000M. At the sub 500M range, the clarity is very good. Loads of YouTube videos. The range finder is just "ok" it's a comparator using typical animal sizes - deer, fox, duck etc. But good enough to be within a couple of metres. Dunno...

Thanks for that. I actually have my own very expensive thermal (rifle) scope, which is pretty good. I may try that. It's a Pulsar Trail.

No not yet sorry, hoping to look over the weekend, but floored with the lurgy atm...

Hi, its fairly new, no more than 15 years old, and a ground floor flat, and not timber framed, Cheers

Thanks to both No idea on sub-floor construction, but will check. I'll get him to do the boiler isolation later in week and see what happens

This isn't for me, it's for a friend. One year old Vokera combi boiler has recently starting to lose pressure. Boiler engineer has been out and checked boiler, pressure reliefs and radiators, with no apparent leaks. The system drops from 1.5bar to 0.5bar in around 12 hours. He reckons it may...

I thought I'd update this for completeness. So system drained, flushed and refilled with MB1 inhibitor. Few days of settling in and bleeding etc. So over a week later and the system doesnt need bleed at all, and the offending towel radiators dont need bled either. I also think the automatic...
