Boilers are by no means infallible. Common issues include leaks, low pressure, overheating and ignition problems.
The majority of modern boilers, when they go wrong, will display a boiler fault code. If you still have the manual for your boiler, this should have a comprehensive list of the fault codes and what they mean. However, if you have not got the manual (or it isn’t easy to get to), the following are the most common fault codes.
E118/F22
Both of these codes are an indication that the boiler is operating with insufficient pressure. This is a fairly common issue that can hinder the efficiency of a boiler but is not, in itself, serious.
This issue can usually be remedied without professional help by repressurising the system. Instructions on how to do this can be found in the boiler manual or online.
E125/F28
Both of these fault codes relate to overheating. Overheating is a serious problem that needs immediate attention in order to prevent further damage. The most common causes of overheating are high pressure, limescale build-up, a blockage within the system, a faulty pump or a faulty thermostat.
E133/F17
Both of these codes are indicative of a failure in the boiler’s ignition process. This may be caused by an interruption in the gas supply or by issues within the ignition system like a faulty pilot light or ignition lead fault. As there are some safety implications, it is wise to contact a professional to address any issues with ignition.
