Your boiler is temporarily pausing to perform a routine internal diagnostic check and will resume normal operation on its own shortly.

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.
