Ice Maker Care; Cleaning - KitchenAid KUIS18PNXW Use And Care Manual

Cleaning

The ice making system and the air cooled condenser need to be
cleaned regularly for the ice maker to operate at peak efficiency
and to avoid premature failure of system components. See the
"Ice Maker System" and the "Condenser" sections.
Exterior Surfaces
Wash the exterior enamel surfaces and gaskets with warm water
and mild soap or detergent. Wipe and dry. Regular use of a good
household appliance cleaner and wax will help maintain the finish.
Do not use abrasive cleaners on enamel surfaces as they may
scratch the finish.
For products with a stainless steel exterior, use a clean sponge or
soft cloth and a mild detergent in warm water. Do not use abrasive
or harsh cleaners. Do not use chlorine bleach on the stainless
steel surfaces.
Ice Maker System
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 upon how hard your
water is. With hard water of 15 to 20 grains/gal.
(4 to 5 grains/liter), you may need to clean the system as often as
every 6 months.
NOTE: Use one 16 oz (473 mL) bottle of approved ice maker
cleaner. To order, call 1-800-422-1230 and ask for Part Number
4396808. In Canada, call 1-800-807-6777.
1. Press selector switch to OFF.
2. Wait 5 to 10 minutes for the ice to fall into the storage bin.
Remove all ice from the storage bin.
3. Unscrew the drain cap from the bottom of the water pan
located inside the storage bin as shown. Allow the water to
drain completely.
4. Replace the drain cap securely on the water pan. If the drain
cap is loose, water will empty from the water pan and you will
have either thin ice or no ice.
5. Read and follow all handling information on the cleaner bottle
before completing the steps below. Use one 16 oz (473 mL)
bottle of approved ice maker cleaner.
6. Pour one bottle of solution into the water pan. Fill the bottle
twice with tap water and pour it into the water pan.

7. Press the CLEAN button. See "Using the Controls." The light
will blink, indicating that the cleaning cycle is in process.
When the indicator light turns green (approximately
70 minutes), the cleaning cycle is complete. During the
cleaning cycle, the system will both clean and rinse itself.

ICE MAKER CARE

8. After the cleaning cycle is complete, remove the drain cap
from the water pan. Look for any cleaning solution left in the
water pan. If cleaning solution drains from the water pan, you
should run the clean cycle again. Be sure to replace the drain
cap securely on the water pan. If the drain cap is loose, water
will empty from the water pan and you will have either thin ice
or no ice.
NOTE: Severe scale buildup may require repeated cleaning with a
fresh quantity of cleaning solution.
9. Push the selector switch to ON to resume ice production.
Condenser
A dirty or clogged condenser:
Obstructs proper airflow.
Reduces ice making capacity.
Causes higher than recommended operating temperatures
which may lead to component failure.
Disconnect power before cleaning.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
1. Unplug ice maker or disconnect power.
2. Remove the two screws in the lower access panel and the two
screws from the base grille area of the front panel support.
3. Pull the bottom forward and then pull down to remove the
lower access panel.
