Filters
Inspect and clean the filters periodically. This should be done every other month or more depending on usage. If 
there is a decrease in wash performance or dishes feel gritty, this is also an indication the filters need to be cleaned.
Protect Against Freezing
If your dishwasher is left in an unheated place during the winter, ask a service technician to:
1
Turn off electrical power to the dishwasher. Remove 
fuses or trip circuit breaker.
2
Turn off the water supply and disconnect the water inlet 
line from the water valve.
3
Drain water from the water inlet line and water valve. 
(Use a pan to catch the water.)
4
Reconnect the water inlet line to the water valve.
Does Your Dishwasher Have an Air Gap?
An air gap protects your dishwasher 
against water backing up into it if a drain 
clogs. The air gap is not a part of the 
dishwasher. It is not covered by your 
warranty. Not all plumbing codes require 
air gaps, so you may not have one.
The air gap is easy to clean.
1
Turn off the dishwasher and lift off the air gap cover.
2
Remove the plastic cap under the cover and clean with 
a toothpick.
3
Replace the cap and cover when the air gap is clean.
Check the air gap any 
time your dishwasher 
isn’t draining well.

it from the Ultra-Fine Filter assembly. See directional 
arrows on the bottom of the Filter Basket. Pull the Filter 
Basket to remove from the assembly, throw away any 
food particles, rinse with warm soapy water, and use a 
sponge to remove any stubborn particles.
Once cleaned, replace Filter Basket back into the 
Ultra-Fine Filter assembly and twist it clockwise to lock 
into place.

hard water. Once cleaned, replace the Fine Filter and 
the Ultra-Fine Filter.
