What CE 207 means
System water pressure too low.
Gas Safe engineer: If pressure drops again or the code remains after repressurising, contact a Gas Safe registered engineer.
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.
Safe check
If the gauge is below 1 bar, you may top up to about 1.5 bar using the filling loop as shown by your installer and the user guide. Do not remove any panel or casing. If pressure drops again or the code remains, contact a Gas Safe registered engineer. You may then press Reset once.
When to contact an engineer
If pressure drops again or the code remains after repressurising, contact a Gas Safe registered engineer.
