How to Fix / Troubleshooting

Safety First: Immediately turn off power at the breaker and close the water supply valve. Do not continue using the dishwasher.

  • Inspect surrounding area: Look under the sink and around the base of the dishwasher for active dripping.
  • Remove toe-kick (if safe): With power off, remove the toe-kick panel and look for signs of water in the base pan.
  • Do not run further cycles: Running the dishwasher can worsen leaks and damage flooring.
  • When to call for service: Internal leaks require a technician to inspect hoses, pump seals, and the sump/tub for cracks and replace faulty components.
