What 1068 means
Outside temp. sensor or lambda probe faulty.
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.
Safe check: Make a note of the displayed code. Do not remove the boiler casing or inspect internal gas, electrical or combustion components.
Gas Safe registered engineer: Use only the homeowner action in your product guide. If this fault or maintenance message remains or returns, contact Worcester Bosch or a Gas Safe registered engineer.
