What F.73 means
Fault: Water pressure sensor not connected or short-circuited.
Gas Safe engineer: Contact a Gas Safe registered engineer for diagnosis of this pressure sensor fault.
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 displayed code. Do not open, adjust or repeatedly reset the boiler. Contact a Gas Safe registered engineer.
