had problems with this boiler not starting, or the fan starting and clicking off after a second, then coming back on a second later and off- and carrying on like this. i changed the air pressure switch, this seemed to work for 10mins before fault reocurred, the fan was snagging so i changed it for another, thought this had fixed it but after 10mins fault reoccurd. the boiler will stay on if i blow down the venturi/air pressure tube. but will not work when piped back up to the flue.
any ideas? cheers
