F22 usually indicates low water pressure or a dry-fire condition — the boiler has detected insufficient water. It can be caused by a leak, a failed pressure sensor or a system that needs re-pressurising. Our engineers can diagnose the underlying cause safely.

F28 is an ignition failure — the boiler tried to fire but failed to ignite. Causes range from gas supply issues to faulty ignition components, and a Gas Safe registered engineer should investigate.

Repeated pressure loss is commonly caused by a leak, a failing expansion vessel or a faulty pressure relief valve. If you are topping up frequently, an engineer should inspect the boiler and system to find the source.
