What 1017 means
1017 indicates that the system pressure is too low.
Safe check
Follow the matching Worcester Bosch user instructions to top up the system to the stated pressure (1–1.5 bar for this model). If the pressure keeps dropping, contact your installer. Do not open the boiler.
When to contact an engineer
Contact your installer if the pressure keeps dropping or the code remains after following the user instructions.
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.
