What No Water Flow means
The manufacturer describes No Water Flow as no water flow.
Safe check
Record the exact display message and do not attempt an internal check. Follow only the user guide restart instruction shown for this message.
When to contact an engineer
The message remains or returns after the user guide action; contact Ideal or arrange a qualified heating engineer.
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.
