E10 Outdoor sensor fault A temperature sensor is sending an impossible value: a faulty sensor, or a loose or short-circuited cable or connector. CautionView details E20 Boiler flow sensor fault A temperature sensor is sending an impossible value: a faulty sensor, or a loose or short-circuited cable or connector. CautionView details E28 Flue safety sensor fault A temperature sensor is sending an impossible value: a faulty sensor, or a loose or short-circuited cable or connector. CautionView details E40 Return sensor fault A temperature sensor is sending an impossible value: a faulty sensor, or a loose or short-circuited cable or connector. CautionView details E50 DHW sensor fault A temperature sensor is sending an impossible value: a faulty sensor, or a loose or short-circuited cable or connector. CautionView details E110 Boiler circuit overheating A temperature safety has tripped: the water is not circulating enough (air, pump, closed valves, dirty filter or heat exchanger) or the circuit is short of water. CautionView details E111 Boiler circuit overheating A temperature safety has tripped: the water is not circulating enough (air, pump, closed valves, dirty filter or heat exchanger) or the circuit is short of water. CautionView details E117 Water overpressure The circuit pressure is too high: overfilling, a worn expansion vessel or strong heating of the circuit. CautionView details E118 Water pressure too low The water pressure in the heating circuit is too low, often because of a small leak, recent radiator bleeding or a slow loss over the months. CautionView details E125 Pump monitoring fault Water circulation is insufficient or detected as abnormal: air in the circuit, a blocked or weak pump, closed valves or a dirty circuit. CautionView details E128 Flame lost during operation The flame went out during operation: disturbed air supply or flue, unstable gas pressure or a dirty sensing electrode. CautionView details E130 Excessive flue temperature A temperature safety has tripped: the water is not circulating enough (air, pump, closed valves, dirty filter or heat exchanger) or the circuit is short of water. CautionView details E133 No flame during the safety period The burner failed to light or the flame was not detected: interrupted gas supply, worn ignition or sensing electrode, gas valve or condensate drain. CautionView details E151 Internal control fault A control, communication or electronic memory fault has been detected: circuit board, controller, wiring or power supply. CautionView details E160 Fan fault The fan is not running at the expected speed or does not stop: a dirty or worn fan, wiring or the electronic control. CautionView details E385 Supply voltage too low A control, communication or electronic memory fault has been detected: circuit board, controller, wiring or power supply. CautionView details E386 Incorrect fan speed The fan is not running at the expected speed or does not stop: a dirty or worn fan, wiring or the electronic control. CautionView details E430 Water flow monitoring fault Water circulation is insufficient or detected as abnormal: air in the circuit, a blocked or weak pump, closed valves or a dirty circuit.
