Is water leaking from the vent? 

Water vapor is released through the vent in the door.  Sometimes the vapor will condensate, and a water spot will be seen on the floor after the door has been fully opened/extended. 

Did someone put dish soap in your dishwasher?

Dishwashing detergent does not create suds, but dish soap does.  If suds, bubbles, or soap foam are present when you open your dishwasher, turn off the dishwasher and allow suds to dissipate. Using the wrong type or too much detergent can cause over-sudsing.  The suds may push water out of the dishwasher, causing leaking or poor wash performance.  Use only detergent specifically designed for automatic dishwashers.

Were the dishes pre-washed or soaked before being loaded?

Residual soap from soaking or spraying dishes with dish soap or other pre-wash dish cleaners can cause excess suds in the dishwasher. Many new spray-on “power” dish soaps are highly concentrated, and their residue on the dishes can cause excessive suds in a dishwasher. 

Pre-washing the dishes before adding them to the dishwasher is not necessary; just scrape off leftover food, bones, toothpicks, and other hard items from the dishes. Dishwashers are designed so that pre-washing dishes is unnecessary. Avoiding pre-washing or spray-on dish soap will save you water, energy, and time.

Are there items between the door seal and the tub of the dishwasher?

• Check that no items, such as silverware, are stuck between the door seal on the dishwasher door and the dishwasher tub. This will cause the door not to shut or seal properly. 
• Check both racks for items that may be stuck and protruding. Remove any item that is protruding outside the rack.
• Check for large food particles around the door seal. Large items could cause the door not to shut or seal properly.

Is the dishwasher level?

Make sure the dishwasher is level. The dishwasher must be supported by the leveling legs/wheels that must be flat on the floor.  The dishwasher must also be square in the cabinet. The door will not seal properly if the tub opening is not square. This is the responsibility of the customer or installer. 

NOTE: Some models will have four leveling legs.
