Drying System

During drying, you can see steam escaping through the vent at the upper left corner of the door. This is normal as the heat dries your dishes.

IMPORTANT: The vapor is hot. Do not touch the vent during drying.

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.

Check under the float for objects that may keep the protector from moving up or down.
