Why it happens.
Hand dish soap or soap residue can create excessive suds. Use detergent made for automatic dishwashers.

Too much foam?
Start with the cause.
A quick visual explanation of excess suds — and the details that matter before you try a fix.
First, stop.
Cancel the cycle and clean up overflow. If water continues leaking, stop using the machine and arrange service.
Check your model.
Whirlpool’s general guidance specifies ¼ cup of cooking oil in an empty dishwasher, followed by a Quick Cycle without detergent. That differs from the simplified spoonful shown here; consult your model’s instructions first.

A dishwasher contains thick foam. A spoonful of oil is added, a rinse cycle is selected, and an animated cutaway shows the foam reducing. An accelerated timer and a clean interior illustrate the outcome. The clip compresses the process; the note above explains its limitations.
