Advanced troubleshooting for service
AUTOMATIC ELECTRONIC
DIAGNOSTICS
This water softener has a
self-diagnostic function for the
electrical system (except into
power and/or water meter).
The water softener monitors
electronic components and
circuits for correct operation. If a malfunction
occurs, an error code appears in the display.
While an error code appears in the display, all
buttons are inoperable except the
MODE/SET
button.
MODE/SET
remains operational so the
service person can perform the Manual Advanced
Diagnostics, see below, to further isolate the
problem.
Procedure for removing error code from
display:
1. Unplug transformer from electrical outlet.
2. Correct problem.
3. Plug in transformer.
4. Wait 8 minutes. The error code will return if the
problem was not corrected.

water softener through the regeneration cycles to
check operation.
Lift off the Salt Hole Cover, remove the top cover
by unlocking the tabs in the back and rocking
forward, to observe cam and switch operation
during valve rotation.

2. The 3 digits indicated water meter operation
as follows: If you don’t get a reading on the
display, with faucet open, pull the sensor from
the valve outlet port. Pass a small magnet back
and forth in front of the sensor. You should get
a reading in the display. If you get a reading,
shut off water supply, unhook the in and out
