Possible Causes

Leaking hose or clamp, Cracked sump or tub, Over-foaming from wrong detergent, Faulty float switch

How to Fix / Troubleshooting

Safety: Disconnect power and turn off water. Expect water in the base.

  • Remove base water: Take off the kick panel and soak up all water from the base pan.
  • Check for foam: If you see excessive suds inside the tub, you may have used non-dishwasher detergent. Run a rinse cycle with a small amount of cooking oil to break down foam.
  • Inspect hoses and sump: Run a short fill test while observing for leaks. Tighten or replace any leaking clamps or hoses.
  • Check float switch: Ensure the float moves freely and is not stuck in the up position.
  • If leak source is not obvious: A slow leak from the tub or pump housing may require a professional inspection and part replacement.
