Leaking Boiler

[Gas Lady Mids]

Hi.. I had a call for a break down of a combi boiler. When I arrived at the property there was no power to the boiler at all.. Customer stated that he tested the fuse in the spur and it is working. Anyway customer informs me that when the boiler went out it kept trying to relight, making several noises then blew the main electrics entirely. Now the boiler is leaking. I took the boiler apart and noticed some discolouration on PCB. I think that has blown so I have ordered a new part, I have drained down the boiler but it is still leaking. from the diverter valve. I have isolated the water supply to the boiler but it is still leaking from the diverter. I have had to turn the mains water off.. Any ideas where this water is coming from guys and why it maybe leaking thru the diverter valve?!!!...

The boiler contains a lot of water.
You can isolate the boiler and drain it down but if you've ever changed a pump in the boiler or diverter valve, no matter how many times you think yoiu've drained it, there's always a bit more.
It's just perseverance.
It'll get there in the end

What boiler is it?

Sorry.. Forgot to say - when I turn the water off at the mains, there is no leak. When i turn it back on, the diverter continues to leak.
How is that possible if i have isolated the water at the boiler???:13:

how/where have you isolated the mains from the boiler?

 

[Gas Lady Mids]

The cold water supply at the boiler... ?? I thought that was right.. Sill new to the game.. Got my certificate last week

The isolation valve could be letting by.
If you're in a fix then it might be worth cutting a ball-o-fix into the incoming cold to the boiler. That way you'd be certain it was off

Ok.. Thanks.. Do you think that if water is leaking from the diverter it will need replacing?

im sure this is a wind up why would you leave an item thats caused a pcb to burn out due to water ingress leaking?or thinking about it why would you leave anyting leaking?

 

[Gas Lady Mids]

No not a wind up.. I was advised today that the diverter could be repaired.. I was asking (In someone else's opinion) if it needs replacing.. meaning is it worth repairing!!!

The PCB has blown before diverter started leaking
