Common boiler error codes & what to do

16/05/20

Boilers can show error codes from time to time, to help you determine whether there’s an issue with the boiler, gas supply or heating system and how to resolve it. Some problems are easy to fix and you can carry out a few simple steps to do it yourself, while others need to be sorted out by a Gas Safe registered engineer.

The error code will appear on the facia display as either two or three numbers, preceded by the letter ‘E’.

Here is a list of the some of the most common error codes, and the recommended action to take.

If the error code persists or does not indicate an issue you can fix yourself, please call Plus Heat on 0808 164 2892 and we can arrange for one of our Gas Safe engineers to visit.

Common Error Codes


E110, E125, E131

Boiler: Generic
Recommendation: Bleed radiators & reset
These 3 separate boiler error codes indicate overheating. To resolve this, bleed your radiators of air and reset the boiler. The error code should then disappear.



E119

Boiler: Generic
Recommendation: Top up boiler pressure
This error code signifies low water pressure. Add water into the system until the pressure gauge indicates a healthy water level, normally between 1 & 2 bar. If you are having to do this more than once every 2 months or if you can see signs of a leak, instruct an engineer.



E133

Boiler: Generic
Recommendation: Reset boiler
This error code means the boiler has failed to ignite. Check if there is gas supply to other appliances (i.e. Hob) and that the gas meter is turned on (and is in credit), then reset the boiler. If there is a rumbling sound or if the error code persists, instruct an engineer.



LC & L2

Boiler: Ideal
Recommendation: Reset boiler
These error codes signify an ignition lockout, usually caused by the boiler switching off. If you are on a prepayment meter, check if you have recently run out of credit, or to check the settings on their thermostat. In either of these cases, wa simple reset of the boiler should resolve your issue.



F1

Boiler: Ideal
Recommendation: Top up boiler pressure
This error code signifies low water pressure. Add water into the system until the pressure gauge indicates a healthy water level, normally between 1 & 2 bar. If you are having to do this more than once every 2 months or if you can see signs of a leak, instruct an engineer.



LF

Boiler: Ideal
Recommendation: Reset boiler
This error code means the boiler has failed to ignite. Check if there is gas supply to other appliances (i.e. Hob) and that the gas meter is turned on (and is in credit), then reset the boiler. If there is a rumbling sound or if the LF code persists, instruct an engineer.



EA 227

Boiler: Worcester Bosch
Recommendation: Reset boiler
These error codes signify an ignition lockout, usually caused by the boiler switching off. If you are on a prepayment meter, check if you have recently run out of credit, or to check the settings on their thermostat. In either of these cases, wa simple reset of the boiler should resolve your issue.



E117

Boiler: Baxi
Recommendation: Bleed radiators
This error code indicates water pressure too high. To reduce the water pressure, bleed the radiators of any air and if necessary, some water until the pressure is within the recommended range (normally between 1-2 bar). The boiler should be off when you do this.



E118

Boiler: Baxi
Recommendation: Top up boiler pressure
This error code signifies low water pressure. Add water into the system until the pressure gauge indicates a healthy water level, normally between 1 & 2 bar. If you are having to do this more than once every 2 months or if you can see signs of a leak, instruct an engineer.



E135

Boiler: Baxi
Recommendation: Reset boiler
These error codes signify an ignition lockout, usually caused by the boiler switching off. If you are on a prepayment meter, check if you have recently run out of credit, or to check the settings on their thermostat.
