What Sr means
Service reminder countdown (0–36 months).
Gas Safe engineer: Book a service with a Gas Safe registered engineer, who will reset the reminder.
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
This is a service reminder, not a breakdown. The boiler keeps working. Book a Gas Safe service; the engineer will reset the reminder. Do not make changes in parameter menus or settings.
