What A42 means
Pressure-transducer fault.
Safe check
Read and note A42 and any visible pressure value. Do not treat this sensor code as an instruction to refill the system.
When to contact an engineer
Arrange a Gas Safe registered engineer to diagnose the pressure transducer and its internal wiring.
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.
