How to Fix / Troubleshooting

Safety first: Immediately turn off power and close the water supply tap. Avoid stepping in water near electrical outlets.

  • Pull out the dishwasher: Carefully slide the unit out of the cabinet to inspect the sides and base for signs of water trails.
  • Inspect hoses: Check the large black or grey hoses connecting the sump, circulation pump, and drain hose for cracks or loose clamps.
  • Check pump seals: Look for water around the circulation pump body, which may indicate a failed seal.

Most internal leaks require replacing the circulation pump assembly or tub-to-pump hoses. Due to flood and electrical risk, this is best handled by a technician.
