AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener self-monitors electronic compo-
nents and circuits for correct operation. If a malfunc-
tion occurs, an error code appears in the display.
Error Codes 01, 02, 03, 04 & 05:
These are the water softener error codes unrelated to
the optional water shutoff valve. While one is in the
display, the SELECT button remains operational so
the service person can perform the Manual Advance
Diagnostics, below, to further isolate the problem.
Procedure for removing error codes 01 through 05
from display:
1. Unplug power supply from electrical outlet.
2. Correct problem.
3. Plug power supply back in.
4. Wait 8 minutes. The error code will return if
the problem was not corrected.
Error Codes 07, 08 & 09:
These error codes indicate a problem with the option-
al water shutoff valve. Make sure that the water shut- off valve is still plugged into the water softener's con-
trol board. To clear one of these codes from the dis-
play, press the RECHARGE button and hold for 3
seconds. If the error code is displayed again after a
minute or two, the water shutoff valve probably needs
to be replaced.
MANUAL ADVANCE DIAGNOSTICS
Use the following procedures to advance the water
softener through the regeneration cycles to check
operation.
Remove the top cover to expose the valve and ob -
serve cam and switch operation during valve rotation.
1. Press and hold SELECT for 3 seconds until "000"
shows in the display, then release.
2. The 3 digits indicate water meter operation:
000 (steady) = Soft water not in use, and no flow
through the meter.
Open a nearby soft water faucet.
000 to 140 (continual) = Repeats for each gallon

4. Use the RECHARGE button to manually advance
the valve into each cycle and check correct switch
operation.
NOTE: Be sure water is in contact with the salt, and
not separated by a salt bridge (See "Breaking
A Salt Bridge" section).
5. While in this diagnostic screen, the following infor-
mation is available and may be beneficial for vari-
ous reasons. This information is retained by the
computer from the first time electrical power is
applied to the electronic controller.
a. Press the UP button to display the number of
days this electronic control has had electrical
power applied.

b. Press the DOWN button to display the number
of regenerations initiated by this electronic con-
trol since the code number was entered.
6. Press and hold the SELECT button until the model
code (nSHC) shows in the display. This code iden-
tifies the softener model. If an incorrect model
code is displayed, the softener will operate on
incorrect configuration data.

q
DOWN button until the correct code shows.
