Technical description: Maximum number of consecutive resets exceeded
What causes this fault?
This fault occurs when the boiler has been manually reset five times within a 15-minute window, causing the system to lock down as a security measure. It is usually triggered because an underlying issue, such as a failure to ignite or a flame sensing problem, led the user to keep pressing the reset button. The boiler stops responding to prevent potential damage or safety risks from repeated failed start-up attempts.
