If you would like to clean hard water filming or other soil buildups from the interior
surfaces of the dishwasher, we recommend using a monthly maintenance product
such as affresh ® Dishwasher Cleaner. If you desire routine cleaning, use a soft
damp cloth.
Some state or local plumbing codes require the addition of a drain air gap between a
built-in dishwasher and the home drain system. Check the drain air gap when your
dishwasher is not draining well.
The drain air gap is usually located on top of the sink or countertop near the dishwasher.
NOTE: The drain air gap is an external plumbing device that is not part of your
dishwasher. The warranty provided with your dishwasher does not cover service costs
directly associated with the cleaning or repair of the external drain air gap.
Clean the drain air gap periodically to ensure proper drainage of your dishwasher. With
most types, you lift off the chrome cover. Unscrew the plastic cap. Then check for any soil
buildup. Clean if necessary.
If you will not be using the dishwasher during the summer months, turn off the water
and power supply to the dishwasher.
Make sure the water supply lines are protected against freezing conditions. Ice
formations in the supply lines can increase water pressure and damage your
dishwasher or home. Damage from freezing is not covered by the warranty.
When storing your dishwasher in the winter, avoid water damage by having your
dishwasher winterized by authorized service personnel.
