Troubleshooting - Whirlpool WHESFC Installation And Operation Manual

AUTOMATIC ELECTRONIC DIAGNOSTICS
This water conditioner has a self-diagnostic function
for the electrical system (except input power and/or
water meter). The water conditioner monitors elec-
tronic 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 PROGRAM button. PRO-
GRAM 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 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.
MANUAL ADVANCE DIAGNOSTICS
Use the following procedures to advance the water
conditioner through the regeneration cycles to check
operation.
Lift off the salt lid, remove the top cover by unlocking
the tabs in the back and rocking forward, to observe
cam and switch operation during valve rotation.
1. Press and hold PROGRAM 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.
000 to 140 (continual) = Repeats for each gallon
