Technical description
Current value in list of faults (Lists are only displayed, and can only be deleted, if faults have occurred)
What causes this fault?
This code appears when someone has accessed the boiler's internal diagnostic menu to view a log of historical issues. It does not represent a new mechanical failure, but rather a digital record of errors that happened in the past. This is often used by engineers during a service to see if the boiler has struggled with things like low pressure or ignition issues over the last year.
DIY fix possible
