Filtration System

Your dishwasher has the latest technology in dishwasher filtration. This triple filtration system minimizes sound and optimizes water 
and energy conservation while providing superior cleaning performance. Throughout the life of your dishwasher, the filter will require 
maintenance to sustain peak cleaning performance.

*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.

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.

The triple filter system consists of 2 parts, an upper filter 
assembly and a lower filter. 

The upper filter assembly keeps oversized items and 
foreign objects, along with very fine food particles, out 
of the pump. 

The lower filter keeps food from being recirculated onto 
your dishware.

The filters may need to be cleaned when:

Visible objects or soils are on the upper filter assembly.

There is degradation in cleaning performance (that is, 
soils still present on dishes).

Dishes feel gritty to the touch.

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