Filtration System - Whirlpool WDT720PADM User Instructions

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.
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.

*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

indicates hard water. For tips on removing spots and stains, see
