What 2971 means
System pressure too low
Safe check
If the pressure gauge is low, top up to the pressure stated in the user instructions using the filling loop. If the pressure drops again, contact a Gas Safe registered engineer. Do not vent or bleed radiators.
When to contact an engineer
If the pressure drops again after topping up, contact 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.
