Overfill Protector
The Overfill Protector (in the front right
comer of the dishwasher tub) keeps the
dishwasher from overfilling. It must be in
place for the dishwasher to operate.
Check under the float for objects that may
keep the protector from moving up or down.

The filter system requires periodic cleaning
as needed. To clean screen:
1. Unload and slide the bottom rack forward.
(Remove bottom rack if necessary to
reach filter screen.)
2. Remove collected particles from the
screen with your fingers or paper towel.
3. Return the bottom rack to original position.
