All 25 fault codes

Code Severity Plain English
0 Low Your boiler is not in a fault state; it is simply indicating that it is running at its maximum power level, usually during a service check or a high demand for heat.
00 Low Your boiler is currently running a self-test at its highest power level and this code is an information message rather than a breakdown.
E01 High Your boiler has failed to light, which means your heating and hot water will not work until the gas flow or ignition is restored.
E02 High Your boiler has switched itself off because it has become too hot inside, usually due to a blockage or a pump failure preventing water from circulating.
E03 High Your boiler has detected an issue with how exhaust gases are being cleared from the system, causing it to shut down for safety.
E04 High Your boiler is repeatedly starting up and then losing its flame, causing the heating and hot water to become unreliable.
E05 High Your boiler's temperature sensor responsible for your heating system has developed a fault, meaning the boiler cannot accurately measure how hot the water is.
E06 Medium Your boiler is having trouble measuring the temperature of your hot water, which usually means it won't be able to provide consistent heat for your taps and showers.
E10 High Your boiler has detected that the water pressure is too low for it to operate safely, which is usually fixed by topping up the system.
E20 High Your boiler has stopped working because a sensor that monitors the temperature of the water returning to the unit has developed a fault.
E28 High Your boiler has detected a problem with the sensor that monitors the temperature of the exhaust gases, causing the system to shut down for safety.
E35 High Your boiler is detecting a flame when there shouldn't be one, leading to a safety lockout to prevent incorrect operation.
E50 Low Your boiler has detected an issue with the sensor for your solar hot water system, which usually means the sensor is faulty or the connection is loose.
E110 High Your boiler has overheated, prompting a safety switch to shut the system down to prevent damage.
E119 High Your boiler has detected that the water pressure in the system is too low to run safely.
E125 High Your boiler has shut down because it is getting too hot inside, usually because the water isn't moving around the system properly.
E130 High Your boiler has shut down because the exhaust gases have become too hot, which is a safety measure to prevent damage to the system.
E133 High Your boiler has tried to light several times but cannot establish a steady flame, likely because gas isn't reaching it or the spark is failing.
E151 High Your boiler's computer brain has encountered an internal software or electronic fault and can no longer communicate with the rest of the system.
E152 High Your boiler’s internal computer has developed a fault and can no longer communicate with the rest of the system.
E153 High Your boiler's computer has temporarily locked itself because the reset button was pressed too many times in a short period.
E160 High Your boiler has detected that the internal fan, which clears waste gases from the system, is not spinning at the correct speed or has stopped working.
E164 Medium Your boiler is having trouble detecting when you turn on your hot water taps, which may result in your water staying cold.
E193 High Your boiler has likely detected trapped air or a blockage inside, which is preventing water from circulating properly and causing it to shut down for safety.
P Low Your boiler is currently performing a routine self-check to calibrate its internal sensors and does not necessarily have a fault.
