What H.02.07 means
H.02.07 indicates that pressure in the heating circuit is permanently low.
Safe check
Follow the Baxi 400 Combi 2.1 instructions to repressurise the heating circuit once.
When to contact an engineer
If the low-pressure fault recurs after repressurising, 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.
