Problem: Water Will Not Run into the Sump Trough
During the Freeze Cycle
Step 1.
Verify water is supplied to the ice machine,
and then start a new Freeze sequence by moving the
ICE/OFF/CLEAN toggle switch to OFF, then back to
ICE.
Step 2. Wait until the Freeze cycle starts
(approximately 45 seconds – the Freeze cycle starts
when the compressor energizes), and then refer to the
chart.
Important
This restart must be done prior to performing
diagnostic procedures. This assures the ice machine
is not in a Freeze cycle water inlet valve safety shut-
off mode. You must complete the entire diagnostic
procedure within 6 minutes of starting.
