How To Decode Boiler Error Codes

How To Decode Boiler Error Codes

The great thing about modern boilers in Leicestershire is that you know when something is wrong. This is because they show error codes. It’s like your boiler is talking to you and telling you what is wrong with them. Some of these error codes can be fixed with a quick reset. You might even need to repressure your system to clear the error. However, you may need a boiler engineer to complete proper boiler care. All of this is easier said than done if you know how to decode the boiler errors.

In this blog post we share some of the more common error codes you might see on your boiler, so you know how to decode them.

Think you might have an issue with the pressure or water flow of your boiler? If you have an Ideal or Baxi boiler you may see the codes F1, E118 or F37. This will show that there is low water pressure, and you need to repressurise the water. Error code A1 shows that there is either little or no water in the system. If you have No Code or 250 it could mead an air lock or no water. The codes F73, F74 or F75 or a Valliant boiler means that there are sensor faults for the water pressure, or no pressure change has been detected. The code EF means that there is a large temperature difference between flow and return.

Are you worried that your boiler is having ignition or flame problems? If you get the boiler error code EA it could mean that the flame has not been detected, the flame is extinguished or there has been an ignition failure. The error codes F28 or F29 or a Valliant or Protherm boiler mean that the flame has not been established or that it has been lost during operation. If you have an Ideal boiler, the codes F2 or L2 mean there has been a flame loss during operation. Meanwhile the L6 code on an Ideal boiler means there has been a false flame lockout. F54, F68 and F93 on a Valliant boiler means there are gas supply issues or combustion quality faults.

You may be concerned about your boiler overheating or having temperate sensor faults. If your boiler is showing E5 boiler error code it means that primary flow sensor has overheated. The error code E9 means the main heat exchanged has overheated or the temperature sensor has failed. An L1 code on an Ideal boiler means that the flow temperature is overheated or there is no water flow. Meanwhile, F76 error code on a Valliant boiler means that the overheating protection has been triggered. Error code F4 or F5 means that there are faults with the flow or return on an Ideal boiler.

These are just some of the most common boiler errors that you may want to decode. However, if you can make a note of the boiler error code, tell us when you call. Our experienced boiler engineers have seen these boiler codes and many more. We can tell you over the phone what you need to do to resolve the issue yourself. Alternatively, if it’s something that needs a boiler engineer, we can book to repair your boiler in Leicestershire at a time that suits you.
