Whirlpool RUD4000 Dishwasher Care, Washing Special Items, Overfill Protection Float, Cleaning

Overfill Protection Float

The overfill protection float (in the front right corner of the dishwasher tub) keeps the dishwasher from overfilling. It must be in place for the dishwasher to operate.

DISHWASHER CARE

Cleaning

Cleaning the exterior

In most cases, regular use of a soft, damp cloth or sponge and a mild detergent is all that is necessary to keep the outside of your dishwasher looking nice and clean.

Cleaning the interior

Hard water minerals can cause a white film to build up on the inside surfaces, especially just beneath the door area.
