How to Fix / Troubleshooting

Safety first: Unplug the dishwasher and close the water tap immediately. Tilt the machine only when water is drained to avoid spillage.

  • Pull out the dishwasher: Carefully slide the unit out from under the counter to inspect the sides and base.
  • Remove panels: Take off the side and/or base panels to locate the source of the leak. Use a torch while running a short fill/wash cycle.
  • Check hoses and clamps: Inspect all rubber and plastic hoses for splits or loose clamps. Tighten clamps and replace damaged hoses.
  • Inspect sump and pump: Look for drips around the sump seal and pump housing. Replace the sump gasket or circulation pump housing if cracked.
  • Do not ignore small leaks: Even minor leaks can trigger the anti-flood system and damage flooring. Repair promptly.
