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.
What F.75 means
F.75 indicates a defective pressure switch.
Safe check
Do not attempt to adjust or repair the pressure switch; arrange a Gas Safe registered engineer.
When to contact an engineer
Arrange a Gas Safe registered engineer to investigate this pressure-switch fault.
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.
