How to Fix / Troubleshooting

Safety first: Unplug the dishwasher and close the water tap immediately. Do not continue using the appliance until the leak is fixed.

  • Pull out the dishwasher: Carefully slide the unit out of the cabinet to inspect the sides and base.
  • Check hoses: Inspect the inlet hose, drain hose, and internal rubber hoses for drips or wetness. Tighten clamps or replace hoses as needed.
  • Inspect sump and pump: Look for cracks around the plastic sump and at the circulation pump seal. Any visible damage requires replacement of the affected part.
  • Dry the base: Mop up water in the base tray and allow the appliance to dry completely before testing.

Because hidden leaks can damage flooring and cabinets, consider professional service for accurate diagnosis.
