MAINTENANCE AND CLEANING
In some areas, the water supply to the ice maker
will contain a high concentration of minerals, and
that will result in an evaporator and auger
becoming coated with these minerals, requiring a
more frequent removal than twice per year. If in
doubt about the condition of the evaporator and
auger, the auger can be removed so the parts can
be inspected.
Note: Water filters can filter out suspended solids,
but not dissolved solids. “Soft” water may not be
the complete answer. Check with a water treatment
specialist regarding water treatment.
For more information on removal of these
parts, see REMOVAL AND REPLACEMENT.
1. To remove the auger, remove the front and top
panels.
2. Push bail clamp off of cover and remove cover.
3. Unscrew and remove ice sweep.
4. Remove ice chute from evaporator.
5. Remove 4 allen screws holding breaker to
evaporator.
6. Pull up to remove auger.
After the auger has been removed, allow the auger
to dry: if the auger is not bright and shiny, it must
be cleaned.
Clean the auger and evaporator as required. DO
NOT HONE THE EVAPORATOR.
7. Replace the water seal.
8. Reverse to reassemble.
