Re: worcester bosch combi boiler
thank you phidom, the pressure info was helpful. I’ve now deduced that I need to replace the auto air vent, which is for the central heating side. the reason there was no hot water is that the leaked water got into the air pressure switch, which shut the boiler down. Reading through forums on the subject, it seems quite common for these auto air valves to leak, but it looks easy enough to remedy. Regards, Tracey
