Hello everyone. I have a Vitodens WB2B 105
Fault code F1.( Flue gas temperature has exceeded 230 deg F ) . Boiler water temperature reaches 115deg then the burner ramps up to high fire . The flue gas temperature goes up to 150 deg then faults out . Replaced the 12 yr old sensor no change , faults out on high fire. With the flue gas sensor removed the boiler will heat up to 170 deg with a flue temperature of 195 deg confirmed with my combustion analyzer. I would really appreciate any advise. Thanks
Ralph
