Error code | Possible fault | Installer action | |
---|---|---|---|
E10 | Outdoor Sensor Error | Outdoor Sensor Fault, Check The Sensor: Check In IP Menu The Outdoor Sensor Value Reads Correctly. | |
E20 | Central Heating Thermistor Sensor Fault | Check resistance reading across the Sensor is approx. 12kohms at 25 degrees c. if not suspect sensor. | |
E28 | Flue Thermistor Fault | Check flue Sensor Value Reads Correctly. Check for blocked flue. | |
E110 | Boiler Overheat Tripped | Check that boiler temp is not over 110 degrees C; Check for continuity across the O/H stat; Check pump for circulation; Clear air from system. | |
E119 | System Pressure Low (< 0.5 Bar) | Check for water leaks; Check the expansion vessel has the correct charge; Add Water Via Filling Loop. Restoring The Correct Pressure Will Reset The Error. | |
E125 | Primary Water Circulation Fault | Check pump; Check that the system is full of water; Clear air from system; Check for blockages in the system; Check that the thermistors are correctly located. | |
E131 | Flue Overheat Lockout | This May Follow A Power Cut, Try Reset; Flue NTC Sensor Exceeded 130C, check resistance across Flue NTC sensor.Possible blocked internal heat exchanger water ways. | |
E133 | Ignition Fault | Check The Wiring; Check The Supply Pressure; Purge The Gas Supply To Remove Air; Check for spark at electrode; Check Ignition and sensing Electrode Condition and Clean/Replace If Necessary; Check Gas Valve is opening; Check Condensate Drain For Blockage. | |
E160 | Fan Fault | Check The Fan And The Cable; Probable cause fan failure. | |
E161 | Fan Fault | Check The Fan And The Cable; Probable cause fan failure. | |
E164 | Heating Flow Switch Error (Ireland) Pressure Sensor Error (UK) | For HEa: Irish System Boilers Have Flow Switches So Check The Switch Operation. For HEa: If UK boiler, fit correct PCB. | |
E167 | PCB Fault | ||
E168 | PCB Lock Out | May Follow Power Supply Problem; Try Reset. | |
E193 | Circulation Fault | This error, if it persists, will be followed by E125. |
