Whirlpool WHES40 - Manual (Page 26)

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 components and circuits for correct operation.
If a malfunction occurs, an error code appears in the display.
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 PROGRAM button.
PROGRAM remains operational so the service person can perform the Manual Advance Diagnostics,
see below, to further isolate the problem.
Manual Advance Diagnostics

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.
