Boiler issues
Former Community Member
We have a Potterton Combi boiler, it was losing pressure. Engineer replaced the diverter valve and said it was corroded. It worked fine for a few days before making a loud banging noise for s few minutes which stopped when the sink taps were on. It was ok for a couple of days and then went off completely. The engineer says the circuit board needs replacing but I'm wondering what caused the issue with the circuit board & whether it will just blow again. I think the boiler is about 8 years old. Any advice welcome.
I was called to a gas boiler today. The home owner's parents are house siting and don't want the pipes to freeze up. The gas boiler was not working and the parents though that the house had an electrical fault. When I arrived I saw that the pressure gauge on the boiler was indicating low. Not being familiar with the make and model I could not find a filling loop. I went to the local plumbing shop and was told that I could not touch the boiler as I was not a Gas Safe registered person. I explained the position and said that I was only touching the plumbing and not the gas. Anyway, after talking to the maker's tech. dept. bloke I was told hoe to re-pressurise the system. It involves a silly plastic key system situated under the boiler.
Do I really have to be Gas Safe registered to re-pressurise an unvented boiler? It is only like pumping up a car tyre. And yes, I do know not to over pressurise the system as the pressure increases with temperature.

Hello Zoom,
It's a horrible way to top up the water, in that boiler!! I have done this several times and you need to force a plastic tool, under the boiler, and it has always spilt some water out, when I've done this.
You don't need to be a gas-safe engineer to do this as it's not within the boiler!
Furthermore... you'll need to find why the pressure has dropped! Check all the valves, on the radiators'.
The inside of the boiler has a 'bladder' that expands, and contracts, etc... hope it isn't that!
