Drain Air Gap
Dishwasher Maintenance Procedure
Storing
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.
To clean the 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.
To help prevent odor or odor-causing residue in your dishwasher, use affresh
®
†
dishwasher and disposer cleaner (recommended) once a
month as part of routine maintenance. Affresh
®
dishwasher and disposer cleaner is effective in all dishwasher brands.
IMPORTANT:
■ Read these instructions and the instructions found on the affresh
®
product package completely before beginning the cleaning
process.
■ Avoid handling the tablet without foil wrapper or gloves.
1. Remove all dishware from the dishwasher. Open the dishwasher and place 1 affresh
®
dishwasher and disposer tablet in the main
detergent tray and close the tray. Place another tablet in the prewash tray or simply place 1 tablet in the bottom of the dishwasher.
Close the dishwasher. Run the dishwasher on the most aggressive cycle - heavy duty scrub, heated water, etc.
2. Place 1 affresh
®
dishwasher and disposal tablet into the garbage disposal. Turn on hot water to slow flow. Run the disposal and
water for 15 seconds. Turn off disposal and water. Do not flush disposal completely with water. Water from the dishwasher will
clean out the disposal. If no garbage disposal, skip this step.
Storing for the summer
If your dishwasher is not in use during the summer months, turn off the water supply and
power supply to the dishwasher.
Storing for the winter
Avoid possible water damage to your home and dishwasher due to freezing water lines. If
your dishwasher is left in a seasonal dwelling or could be exposed to near freezing
temperatures, have your dishwasher winterized by authorized service personnel.
