Error Messages - Beretta POWER X 50 DEP Installation Manual

4 5 4 Error messages

The boiler is equipped with a self-diagnostics system in or-
der to help the maintenance personnel identify the causes
of any anomalies.
When a technical anomaly occurs, the display on the left
will either show the letter "A" or the letter "E", while the dis-
play on the right will show a numeric error code, which will
allow the maintenance personnel to identify the possible
cause.
- If the letter "A" appears on the left-hand display, this
means that the "RESET" button will have to be pressed
after the cause of the fault has been eliminated.
- If the letter "E" appears on the left-hand display, this
means that the boiler will resume functioning normal-
ly, without having to press the "RESET" button, once
the cause of the fault has been eliminated.
The list of the error codes and the descriptions of the rela-
tive anomalies are provided below:
