Technical description
Waiting time: Measuring program. The product is within the waiting period as a result of the measuring programme.
What causes this fault?
This status occurs when the boiler performs a routine self-test to ensure its internal sensors and burning process are accurate. It is a programmed pause where the system double-checks its own performance data before continuing to heat the home. You don't need to take any action as the boiler hasn't broken down; it is simply finishing a brief internal quality check.
DIY fix possible
Wait for 5 to 15 minutes for the program to finishMonitor the display to see if the status code changes to a heating or hot water demand codeIf the code persists for over an hour, try a simple reset of the boiler
