Error Codes
The Accusoft Plus microprocessor is equipped with an advanced error detection system. During
all operating modes the softener’s electronics are performing self-diagnostics to ensure that the
unit is operating correctly. There may be times, however, when something may occur that could
cause the unit to improperly operate. In those instances the microprocessor will identify the exact
problem and alert the user with an error code. Shown below is a description of the error codes.
Beeping only occurs between the hours of 8:00 am and 8:00 pm. Beeping can be silenced by
pressing any key.
To reset an error, press and hold for 10 seconds the ‘Program’ button. The unit will beep and
check to see if indeed the error has been fixed. If the error was not fixed, the board will re-
display the error code. If the error code does not reset please contact your local Culligan Dealer.
For additional troubleshooting or service needs, please contact your local Culligan Dealer.

CHECK
SALT
A/S mode;
control detected
no brine during
brine rinse cycle.
A very distinct signal is expected
from the probe during brine
rinse; lack of this signal means
no brine was detected.
Once this alert is
triggered, the A/S is
no longer a valid regen
trigger. The alert can
only be cleared after a
successful regeneration
of the resin bed.
