GENERAL INFORMATION (Cont.)
Whirlpool® and KitchenAid® Global Wash Filtration System
This dishwasher has an updated technology in dishwasher filtration. The triple filtration system minimizes sound and optimizes
water and energy conservation while providing superb performance. Throughout the life of the dishwasher, the filter will require
maintenance to sustain peak cleaning performance.
The triple filter system consist of a fine-filter plate and a dual filter cup assembly.
n The fine-filter plate protects the wash pump and water delivery system. It also
removes moderate size particles from recirculation onto the dish-load.
n The dual filter assembly protects the drain system from large objects while
collecting the smallest particles for the improved cleaning performance.
The filters may need to be cleaned when:
n Visible objects or soils are on the filters.
n There is a degradation in cleaning performance (that is, soils still present on
dishes).
n Dishes feel gritty to the touch.
It is very easy to remove and maintain the filters. The chart below shows the recommended cleaning frequencies.

*Manufacturer's recommendation: This practice will conserve the water and energy that you would have used to prepare your dishes.
This will also save your time and efforts.
Very Hard Water
If you have hard water (above 15 grains), clean your filter at
least once per month. Building up white residue on dishwasher
indicates hard water.

Cleaning Instructions
IMPORTANT: Do not use wire brush, scouring pad, etc., as they
may damage the filters.
Rinse the 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.
Filter Reinstallation Instructions
1. Place the fine-filter plate under the locating tabs in the
bottom of the dishwasher so the round opening for the
Dual-Filter Assembly lines up with the round opening in the
