My boiler no longer fires up.
If I switch either HW or CH on (or both) the only lights I get are Boiler On and the Fan On seems to 'glow' rather than being fully 'on'.
All other lights (Overheat, Pilot On & Burner On) remain off. I've tried turning thermostat to "off" then waiting 10 seconds & switching back on but this makes no difference. Any ideas what the problem may be?
