Customer reply replied 4 months ago
error code flashing 228
Error code 228 on this model indicates that the unit was unable to successfully perform pressure switch calibration, which is a process the unit performs on heating startup to “tell itself” where the low and high fire pressure switches are closing. Check your flue and intake piping outside for blockages. If no blockages, blow through the pressure switch tubing to ensure that it isn’t blocked. If the piping and tubing aren’t blocked and the unit still won’t pass calibration, you will either need a new switch, or there will be a deeper issue that would require specialized tools and training to find.
