Troubleshooting
The troubleshooting chart shows the error codes that
could appear, and the possible malfunctions for each
code.
While an error code appears in the display, all buttons
are inoperable except the SELECT / MENU button.
SELECT / MENU remains operational so the service
person can perform the Manual Advance Diagnostics,
see below, to further isolate the problem.
Procedure for removing error code from dis-
play:
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.
MANUAL ADVANCE DIAGNOSTICS
Use the following procedures to advance the water
softener through the regeneration cycles to check
operation.
Slide open the salt lid and remove the softener’s top
cover to observe cam and switch operation during
valve rotation.
1
. Press and hold SELECT / MENU for 3 seconds until
“000” shows in the display, then release.
2
. The 3 digits indicate water meter operation as fol-
lows:
000 (steady) = Soft water not in use, and no flow
through the meter.
Open a nearby soft water faucet.
Model EP 7130: 000 to 199 (continual) =
Repeats for each gallon of water
passing through the meter.
Model EP 7140: 000 to 140 (continual) =
Repeats for each gallon of water
passing through the meter.
NOTE:
If you don't get a reading in 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. If you get a read-
ing in the display with the magnet, unhook the
in and out plumbing and check the turbine for
binding (See Figure 30).
3
. The letter “P” and a dash (or dashes) indicate
POSITION switch operation (See Figure 31). If the
letter appears, the switch is closed. If the dash
shows, the switch is open.
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
r
UP button to display the number of
days this electronic control has had electrical
power applied.
b
. Press the
s
DOWN button to display the num-
ber of regenerations initiated by this electronic
control since the code number was entered.

AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener has a self-diagnostic function for
the electrical system (except input power and/or water
meter). The water softener monitors electronic com-
ponents and circuits for correct operation. If a mal-
function occurs, an error code appears in the display.
