WATER DISTRIBUTION TUBE CLEANING
When you find that the ice cubes are incompletely formed or the output of ice cubes is low, the water
distribution tube may be blocked. Set the power switch to OFF. Unscrew the six screws holding the top panel
and remove the panel. You will see the water distribution tube. Rotate the water distribution tube so that the
holes in it are facing up. Using a toothpick or similar tool, dredge the holes, then rotate the water distribution
tube back to its original position. If the tube is badly blocked, clean it as follows:
1. Shut off the water and power supplies.
2. Disconnect the water hose from the distribution tube.
3. Lift one side, remove the distribution tube.
4. With a brush, clean the tube with a dilute solution of warm water and a mild detergent such as dish washing
liquid. After removing the dirt and lint from the surface, rinse the tube with clean water.
5. Replace the distribution tube.
6. Reconnect the water supply and power supply lines.
7. Re-attach the top panel.
ICE-MAKING SYSTEM CLEANING
Minerals that are removed from water during the freezing cycle will eventually form a hard, scaly deposit in the
water system. Cleaning the system regularly helps remove the mineral scale buildup. How often you need to
clean the system depends on how hard your water is or how effective your filtration may be. With hard water of
15 to 20 grains/ gallon (4 to 5 grains/liter), you may need to clean the system as often as every 3 months.
1. Set the power switch to OFF.
2. Remove all ice cubes from the storage bin.
3. Remove the screws in the front cover, push forward to remove the front cover. Locate the control box.
4. Keep the ice maker connected to the water supply. Pour 8 oz. of Nickel-Safe Ice Maker Cleaner Solution
into the water tank.
5. Turn the power switch ON. Within 3 minutes, press the CLEAN button. The machine will run the Automatic
Clean mode. The green Ice Making and the yellow Ice harvest LEDs will blink.
6. The cleaning cycle will continue for 30 minutes unless you press the power switch (you can press the
power switch to stop the cleaning cycle any time during the 30 minutes). After cleaning, the green Ice
Making and yellow Ice Harvest LEDs go on steady and the machine returns to Stand-by mode.
7. The dirty water must be drained out completely. Perform steps 2 and 3 in the Interior Cleaning section.
8. Repeat steps 4 to 6 above three times to rinse the ice-making system completely.
NOTE: Do not add Ice Maker Cleaner Solution to the water trough during the rinses.
9. Reassemble the front cover.
10. If you want to make ice cubes after cleaning, turn off the power switch, drain off the waste water, then turn
on the power switch. The next ice-making cycle will begin.
11.
Discard the first batch of ice.
SANITIZING THE ICE-MAKING SYSTEM
1. Set the power switch to OFF.
