We have a standing instruction preventing any live testing except at the consumer unit. When called to a heating fault this pretty much removes significant diagnostic options making fault finding a pain (Not just on heating systems). Ironically currently our gas safe engineers with less electrical training, test equipment and experience are not restricted in the same way. Were pretty much limited to covers on function checks and continuity testing or just changing out components based on likely cause.
How on earth can you find most faults with no live testing and within a respectable period of time? I'd certainly ignore that standing instruction as would 99% of qualified sparks that know what they're doing.
@@helijim It was either that instruction or have a second safety operative with you at all times. This is in domestic properties BTW not commercial/industrial. Only live testing at consumer unit with safety barriers. Basically that standing instruction is impractical most of the time and as you pointed out drags fault finding out on control circuits especially. this instruction doesn't include gas safe engineers at the moment so they can probe away with a multimeter in a boiler or wiring centre and I can't. They were going to make it across the board but hit a problem that would either task an electrician with every gas safe engineer as a team or put the gas engineers on some courses and issue them a MFT when they can use one. As its a standing instruction were stuck with it, impractical or not.
We had a fault on our condensing boiler last year. It has a reservoir tank and pump, external to the boiler, which pumps the condensate up to the loft and out through the stink pipe. The pump stopped working, the reservoir tank reached it’s maximum level and disconnected power to the boiler. I installed a new pump and the boiler started working. The same issue happens, where the condensate is gravity fed to the outside and freezes up in freezing winter temperatures.
Gas technician here. This is a common fault on these boilers. These were made by Glow Worm for BG. I don’t remember which model though. The problem is the PCB and there is no way to repair that, you just have to replace the PCB. The problem usually occurs when the boiler is switched off and back on for a service. Sometimes they will start cycling which is when they will go off/on repeatedly for a good 5 minutes or so and then either die completely or come on and work fine. Hope this helps.
Unless you’re gas safe you don’t really need to take the cover off a boiler to fault find. You can’t legally take a cover off that forms part of the combustion seal.
No sparks should be touching inside a boiler, Ready the M.I unless you are Gas safe registered, how can you confirm you haven’t now caused CO leakage.. Or Gas leakage..
On that particular boiler the outer cover and wiring terminals are NOT within the room sealed section of the boiler - so not an issue. On some boilers you cannot access the electrical connections this way. In that case I would agree with you. For some reason more modern boilers have moved the electrical connections into this room sealed area which to be honest seems like a really dumb idea.
@@jasonwatson9011 sorry if the guy got it working how can he test the integrity of the flue.. as he is the last person working on the boiler.. he is HET.. even if he wasn’t working on the flue he is responsible.. as soon as you take the case off you are responsible for the boiler.. weather it is AR or ID..
He's taken the cover off to access the electrical connections and didn't disturb anything to do with the combustion chamber or flue? I'm not being argumentative, just mildly pedantic because that's the nature of us electrical wizards ;-) I've been to retrofit smart controls to recently installed boilers and found incorrectly rated fuses in the spur, no ferrules on stranded conductors, 5-core cables with wires cut short/off or left floating because they weren't being used, 2-core T&E with the CPC being used as a switched live, so likewise, Heating Engineers shouldn't be touching the electrical connections unless they're suitably qualified?
So what about the heating engineer that connects the boiler to a spur/fused connection unit? How can you confirm you now haven't caused a break in the earth to the boiler or that there wasn't one there before? Do you guys carry an earth loop impedance tester? Exactly!

@@jasonwatson9011 I feel your pain.

Normally if display is off it means that 5 or 3.3 v regulated power supplies are knackered on PCB.
Did you confirm it was 230v reaching the board and not just indicated voltage.
Im surprised the GSH Group inc have not stopped you using GSH Electrical as a name.

Hi did you figure out what was wrong with it? I have exactly the same problem
Could be one of the fast blown fuses on the board

It’s a room sealed boiler. The outer casing douse house a seal. The combustion chamber cover does.
@@benYMSB still u are not allowed to take off it illegal
@@Mchy0my point was taking it off doesn’t compromise the integrity of the seal.
was the fault found?
I would of swap the fuse for another just to check never no
Ours was the board
But we'd already changed the timer and the switchy thing in the front 🤦
was fault found?

He's removed a decorative cover, if you're gas safe I suggest you read up on your own regs.

If you are not gas Engineer you shouldn’t be taking off the case off, that’s illegal
You shouldn't be working on a boiler unless you are AG's registered
