Error List; Permanent Errors - Beretta POWER MAX Installation And Operation Manual

3.4 Error List

When a display has a technical fault, a numeric error code appears that will enable the maintenance operator to identify the possible cause.
There are 3 categories of errors:
1 Permanent: errors that require a manual reset
2 Temporary: errors that are automatically reset once the cause that generated them is removed or stopped
3 Notices: simple warnings that do not block the appliance's operation

Checks
Check gas supply pressure
Check ignition spark
Correct amount of air
Check for voltage at the gas valve
Check the integrity of the wire connections
between gas valve and control board
Press RESET button to display the Block-
ing error description
Check that the fan is connected to the
power supply
Check PWM connection of the fan
Check the pump to verify the flow circu-
lation
Check if the valves on hydraulic circuit are
open
Check the safety thermostat
Solutions
Control board replacement
If the gas supply pressure is incorrect, it
must be adjusted to the correct pressure
If spark is not present check for correct
ignition electrode position
If the combustion air pressure is incorrect,
inspect the vent system and eliminate any
obstructions
If the voltage at the gas valve is not the
same as the boiler power supply, replace
the control board
If wires are damaged, replace them
If the wiring is intact, replace the gas valve
or the control board
a) If the error appears during operation,
replace the control board
b) If the error appears when the boiler is
starting up (using main switch), check that
the limit thermostat (and wiring) is integral
Remove the cause of the Blocking error
If there is no voltage, replace the control
board
If no PWM signal is present, replace
control board
Replace the fan
