Cleaning the Exterior

Clean the exterior of dishwasher with a soft, damp cloth and 
mild detergent. If your dishwasher has a stainless steel exterior, 
a stainless steel cleaner, such as affresh

®

 Stainless Steel Cleaner 

is recommended. Avoid using abrasive cleaning products on the 
exterior of the dishwasher.

Cleaning and Maintaining the Interior

Many detergents may leave white spots or a white residue on dishware 
and on the interior of the dishwasher. Over time this residue can 
become unsightly and could affect dishwasher performance. Use of a 
dishwasher cleaning product such as affresh

®

 Dishwasher Cleaner can 

help to remove the residue. Monthly use of affresh

®

 Dishwasher 

Cleaner is recommended to help maintain the dishwasher. Follow 
package directions. 

NOTE: Whirlpool recommends the use of high-quality, premeasured 
detergent tablets or packs and the use of rinse aid for dishwasher 
cleaning and daily care.

Cleaning the Filters

If you have a drain air gap, 
check and clean it if the 
dishwasher isn't draining well.

To Reduce Risk of Property Damage During Vacation or Extended 
Time Without Use: 

When 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 cause damage to 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.

It is very easy to remove and maintain the filters. The chart below shows the recommended cleaning frequency.

*Manufacturer's recommendation: This practice will conserve the water and energy that you would have used to prepare your dishes. This will 

also save you time and effort.

Very Hard Water

If you have hard water (above 15 grains), clean your filter at least once 
per month. Building up of white residue on your dishwasher indicates 
hard water. For tips on removing spots and stains, see the 
“Troubleshooting” section in the full User Instructions.

Cleaning Instructions

IMPORTANT:  Do not use wire brush, scouring pad, etc., as they may 
damage the filters.

Rinse filter under running water until most soils are removed. If you 
have hard-to-remove soils or calcium deposits from hard water, a soft 
brush may be required.
