Stop the dishwasher now, then clean up the foam before it soaks into the cabinet base and floor. Suds pouring out of the door almost always mean the wrong soap got in, usually hand dishwashing liquid. The fix takes about half an hour and rarely needs a repair visit.
Do this first
- Stop the cycle. Press Cancel or Off. Whirlpool's first two steps for excess suds are to stop the dishwasher immediately, cancel the wash cycle and clean up any overflow (Whirlpool).
- Mop up the floor and the front of the cabinet. Get towels under the door edge and along the toe kick, where water runs back under the dishwasher.
- Keep the floor around you dry while you work. If water has spread toward an outlet or the garbage disposal switch, don't touch either while you're standing in water. Turn off that circuit at the breaker first, as long as you can reach the panel from dry floor.
- Remove the dishes and set them in the sink. They'll need a rinse anyway.
In the next few hours
- Scoop out the foam inside the tub with a cup or a towel. Don't add water to "rinse it down". That makes more suds.
- Use the oil method. Whirlpool's instructions are to add ¼ cup of vegetable or other cooking oil to the bottom of the dishwasher and run a Quick Cycle with no detergent or dishes. The oil suppresses the suds and helps flush the soap through. Repeat if suds are still present.
- Watch the first minutes of that cycle with a towel ready. If foam starts to push out of the door again, cancel and scoop more out before restarting.
- Dry under and around the dishwasher. Pull off the lower kick panel if it unclips easily and check the floor beneath. Foam that seeped under the unit leaves water behind, and the EPA's window for drying wet materials before mold can start is 24 to 48 hours (EPA).
- Rewash the dishes with proper dishwasher detergent once the tub runs clear.
Before the technician arrives
Most suds overflows end with the steps above. Call for service if the dishwasher still leaks with the correct detergent, won't drain the oil-and-water cycle, or shows an error code. If you do, note:
- The model and serial number. On most dishwashers the label is on the edge of the door or the side of the tub frame, visible when the door is open.
- What went into the dispenser, and whether anyone pre-rinsed dishes with dish soap.
- Where the water appeared: the door corners, under the center of the door or from under the cabinet.
- Any error codes or flashing lights, and whether the dishwasher drained between cycles.
What not to do:
- Don't run a full normal cycle to "wash the soap out". It can push more foam out of the door.
- Don't pour salt, vinegar or other home remedies in on top of the soap. Stick with the manufacturer's method.
- Don't keep running it if water collects under the unit after the suds are gone. That points to a separate leak.
How to keep it from happening again
- Use only dishwasher detergent. Whirlpool's leak guide says to use only dishwasher detergent, never dish soap, and lists over-sudsing as a cause of door leaks.
- Keep dish soap away from the dishwasher. Store hand soap at the sink and the dishwasher detergent near the dishwasher so the two aren't confused, especially with guests or kids helping.
- Don't pre-wash with dish soap or spray-on cleaners. Whirlpool notes that soap residue from pre-washing can cause suds too.
- Measure detergent to the manual's guidance, and use less if your dishwasher has a short or eco cycle.
If water keeps rising even without suds, see what to do when your dishwasher won't stop filling. If it's leaking with the right detergent, our dishwasher service page explains what a repair visit covers.

Keep in mind: Suds alone rarely damage a dishwasher, but water left under the cabinet can damage the floor long after the foam is gone.
