The information on this site is general guidance to help you understand what your boiler's display is telling you. It isn't a substitute for your boiler's own manual or for a visit from a qualified engineer.
Only carry out tasks that your boiler's user manual describes for the user. By law, any other work on a gas appliance must be done by a Gas Safe registered engineer.
If you smell gas, leave the property and call the National Gas Emergency line on 0800 111 999. If anyone has symptoms of carbon monoxide poisoning, such as headaches, dizziness or nausea, get fresh air and seek medical help.
Boiler models differ. Codes and recommended pressures can vary between models and over time, so always check your own manual.
