All 22 fault codes

Code	Severity	Plain English	DIY
A01	High	Your boiler has failed to light the flame, which means you currently have no heating or hot water.	Yes
A02	High	Your boiler thinks it sees a flame even though it hasn't started the burner yet, which is a safety conflict that prevents it from running.	Engineer
A03	High	Your boiler has likely overheated because the water isn't moving through the system properly or a safety sensor has detected a temperature that is too high.	Yes
A04	High	Your boiler has shut down because it detected a repeat issue with its exhaust system three times in one day.	Engineer
A05	High	Your boiler has stopped working because its internal fan, which safely exhausts gases, is not communicating correctly with the main control board.	Engineer
A06	High	Your boiler is failing to detect a flame after it tries to start up, meaning it cannot provide heating or hot water.	Engineer
A41	High	Your boiler has lost communication with the internal sensor that monitors water temperature, meaning it cannot safely heat your home or water.	Engineer
A42	High	The boiler's internal thermometer is sending an incorrect signal to the control board, preventing the system from heating your water correctly.	Engineer
A61	High	Your boiler's main internal computer has developed a technical fault and can no longer communicate with the rest of the system.	Engineer
A62	High	Your boiler's computer cannot talk to the gas valve, meaning it cannot light the flame to provide heating or hot water.	Engineer
A63 / A64 / F66	High	Your boiler's main internal computer has developed a technical fault and can no longer control the heating system safely.	Engineer
F07	High	Your boiler has detected that the exhaust gases are getting too hot, which has caused the system to shut down for safety.	Engineer
F10	High	Your boiler's internal sensor that monitors the temperature of water leaving the unit has stopped working correctly, and the system has shut down to prevent overheating.	Engineer
F11	High	Your boiler's internal sensor that monitors the temperature of the water returning to the unit has stopped communicating correctly, causing the system to shutdown for safety.	Engineer
F13	High	Your boiler's internal temperature sensor has stopped sending the correct information to the control board, preventing the system from operating safely.	Engineer
F14	High	Your boiler has stopped working because it cannot correctly measure the temperature of the water leaving the unit.	Engineer
F15	High	Your boiler has stopped working because it cannot properly control the fan that removes waste gases from the system.	Engineer
F34	High	Your boiler is not receiving enough electricity from the mains supply to operate its electronic components safely.	Engineer
F35	Medium	Your boiler has detected an issue with the quality of the electricity coming into your home, meaning the power supply is not stable enough for it to operate safely.	Engineer
F37	High	Your boiler has stopped working because the water pressure inside the system has dropped too low to operate safely.	Yes
F43	High	Your boiler has stopped working because water is not moving through it properly or there is trapped air causing it to overheat.	Yes
F52	High	Your boiler has detected a problem with the internal sensor that monitors water temperature or flow, meaning it cannot safely regulate how much it heats the water.	Engineer
