Close the dishwasher door and press "Cancel" to drain the dishwasher and turn it off.
Grab the dishwasher on both sides and carefully pull it out from under the counter.
Locate the drain hose on the bottom of the floor and place a towel underneath the hose to prevent water from spilling onto the floor.
Squeeze the clamps on the drain hose with the pliers to open the clamps. Push the drain hose onto the drain hose connector.
Release the clamps over the drain hose connector to secure the drain hose to the dishwasher's drain hose connector.
Carefully lift the dishwasher up and push it to the back into the under counter opening.
