flue is fine, air intake is fine, hoses no slits or holes, replaced air pressure switch and venturi but the the micro switch still isnt making contact when the fan is running? tested coil on fan got overload/infinity fan fault then???
thanks, put the thermostat down to 2 and the boiler still came on then cut out after a minute. looks like its the pump then! is there anway i could get this pumps to go without actualy getting to it like say a powerflush or installing a second pump on the system with this?
thanks for the help, problem is its an older house no access to cellar where pump might be! checked everywhere no sign of it so could only be there all behind a wall or unit! anyway a can get this pump moving again if it is jammed and cant get to it?
Have you had it serviced recently, sounds like weak thermocouple or pilot flame
if it was the thermocouple would it not come on at all? pilot flames looks gd. the pipes coming from the boiler about 80cm away r still cold which made me think it could be the pump not circulating the heat?
have a problem with an older baxi model! when calling for heat boiler ignites and comes on fine, lasts for about a minute then cuts out before pipes can even get warm! also pump could be under-floor which is sealed off so no way to check it!??
