Baxi Luna3 310fi throwing error 03
Tech recently Replaced pressure switch but error continued every month or so. Flue isn't blocked . Have 120 volts at fan during pre start up. Can not re create error . I put it in high and low fire to try and make it trip. Vent is properly pitched away from house. No signs of condensation in pressure switch tube. Any suggestions?
