What 92 means

ADIO electronics module communication error.

Gas Safe engineer: The code remains or returns after the step above, or no home step applies; arrange diagnosis by 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

Note the code shown on the display. Do not open, adjust or repeatedly reset the boiler. Contact a Gas Safe registered engineer.
