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.
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.
You may have to be if you do it in the course of trade. Otherwise, a householder, or his chum, or a neighbour, etc. may re-pressurize it.
The expansion tank bit is like pumping up a car tyre, the other bit is more like filling a kettle. But you knew that.
If you ask me, a thermocouple is an electrical item, but Screwfix will not sell them to me. ?
