Some advice, please. I have to give the pressure switch a tap to ignite the boiler - I thought I would fix the problem by replacing the switch.....an easy job, only a couple of wires and a couple of vacum hoses to swop over.
New PS installed - the same problem.....it appears to operate from a change in pressure in the fan chamber, any ideas what the fault might be ?
Many thanks......Steve
