Auger Maintenance

Auger:

In some areas, the water supply to the ice machine 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. Disconnect electrical power to the ice machine.

2. Turn off the water supply to the ice machine.

3. To remove the auger, remove the front and top panels.

4.Push back the bail clamp holding the ice chute cover to the ice chute, and remove cover.

5.Remove ice chute from evaporator.

6.Remove four (4) Allen screws holding breaker to evaporator.

7.Drain the evaporator by lowering and uncapping the evaporator drain hose.

8.Pull up to remove the auger. After the auger has been removed, allow the auger to dry: if the auger is not bright and shinny, it must be cleaned.

9.Clean the auger and evaporator as required. DO NOT HONE THE EVAPORATOR.

10.Replace the water seal.

11.Reverse to reassemble.
