When to contact an engineer
Use only the homeowner action in your product guide. If this fault or maintenance message remains or returns, contact Worcester Bosch or a Gas Safe registered engineer.
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.
