What 51 means
Climatic RF communication fault.
Gas Safe engineer: If the fault remains after replacing the Climatic RF controller batteries, contact a Gas Safe registered engineer.
A boiler fault code alone is not a gas or carbon-monoxide emergency. If you smell gas, a CO alarm sounds, or someone has possible carbon-monoxide symptoms, leave and call 0800 111 999 from outside.
Renting? Report it to your landlord or housing provider first. They are responsible for gas safety and boiler repairs, and the repair should not cost you.
Safe check
Replace the Climatic RF controller batteries only. If the fault remains, contact a Gas Safe registered engineer.
When to contact an engineer
