It is recommended that you replace the water
filter:
• Approximately every six months.
• When the water filter indicator turns on.
• When the water dispenser output decreases.
• When the ice cubes are smaller than normal.
The water pressure must be between 20 and 120
psi on models without a water filter and between
40 and 120 psi on models with a water filter.
If the problem persists, it may be necessary to
contact a plumber.
Reverse osmosis filtration systems can reduce
the water pressure below the minimum amount
and result in icemaker issues.
(Refer to Water Pressure section.)
The tubing can kink when the refrigerator is
moved during installation or cleaning resulting
in reduced water flow. Straighten or repair the
water supply line and arrange it to prevent future
kinks.
