Hi
I have had plenty of information from reading the other topics and am hoping your generosity will help me out on this one.
This is our 2nd winter in this house and the approximately 10yr old British gas 330 (glow worm) started developing faults. It started with a f5 fault on heating water only. A Plumber was called who decided the pump was OK but there's sludge in the system and possibly sludge in the boiler causing this. So he wanted to charge £350 for power flushing to 'hopefully' sort out the fault. That was a lot of money to spend on a hope so I got a fernox x400 myself, left in the system for a week and drained it. I was hoping to see a lot of dark water but to my surprise water was mostly clear but interspersed with dark water every now and again. This was partly because I didn't switch on the hot water that week and only kept the central heating on.
After that the boiler was switched on but the f5 fault hadn't gone away so I keep resetting the safety button. On central heating the f6 fault keeps appearing and disappearing.
Current status is that we just use the electric shower and boiler is doing a good job of keeping the house warm day and night even through these f6 faults.
I thought this was probably an airlock so have let the air out of radiators couple of times but this doesn't seem to have a big effect on the faults.
Called glow-worm and they want to charge £260 to fix this, local Bosch installer (and I assume boiler engineer, rather than a plumber) wanted to charge £89 call out fee to have a look which is again lotsa money.
So I was hoping someone experienced here might be able to suggest if this due to an airlock. If not what should be done about this?
Kind regards
