Troubleshooting - Morton System Saver M20 Installation And Operation Manual

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.
While an error code appears in the display, all buttons
are inoperable except the SELECT button. SELECT
remains operational so the service person can per-
form 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.
