How to Fix / Troubleshooting

Safety first: Disconnect power and be prepared for water spillage when moving the appliance.

  • Drain base tray: Pull the dishwasher out and gently tilt it to allow water to escape from the base. Use towels to soak up water.
  • Identify leak source: With panels removed, run a short cycle and look for drips from the circulation pump, heater, hoses, or door area.
  • Correct detergent use: Ensure only dishwasher tablets or powder are used, not hand-wash liquid.
  • Repair leak: Replace any cracked hoses, seals, or components causing the leak.
