What F.29 means
F.29 indicates an operating failure after unsuccessful re-ignition, associated with intermittent interruption of the gas supply. The manual warns that some shared-table codes may not be visible on every product variant.
Safe check
Do not attempt to adjust or repair the appliance; arrange a Gas Safe registered engineer.
When to contact an engineer
Arrange a Gas Safe registered engineer to investigate this operating fault.
Safety notice
A boiler fault code alone is not a gas or carbon-monoxide emergency. If you smell gas, a CO alarm sounds, anyone feels unwell, or there is an unsafe flame, leave and call 0800 111 999 from outside.
