Installation
Ice is clumped together
Power failure
The unit is newly installed
Throw away the ice (about 20 pieces) first made after refrigerator installation.
The first ice and water may include particles or odor from the feed water pipe or
feed water box.
This is also necessary if the refrigerator has not been used for a long time.
Never store beverage cans or other foods in ice storage bin for the purpose of rapid
cooling.
Such actions may damage the automatic ice maker.
Never remove the ice maker cover.
Sometimes level the surface so that the ice storage bin is fully filled with ice.
Ice may pile up just around the ice maker causing the ice maker to think that the ice
storage bin is ful.
If discolored ice is dispensed, immediately contact Service Center.
Do not use until problem is solved.
When ice is clumped together, take the ice clumps out of the ice storage bin,
break them into small pieces, and then place them into the ice storage bin
again.
When the ice maker produces too small or clumped ice, the amount of water
supplied to the ice maker need to adjusted. Contact the service center.
If ice is not used frequently, it may clump together.
Water may drop into the freezer compartment. Take the ice storage bin out and
discard all the ice then dry it and place it back.
It takes about 12 hours for a newly installed refrigerator to make ice in the
freezer compartment.
