Possible Causes

Water not heating to target temperature, Very cold inlet water, Faulty turbidity sensor misreading soil level, Low water pressure causing long fills

How to Fix / Troubleshooting

Safety first: Allow the cycle to complete before opening the door mid-wash.

  • 1. Check water temperature: Run hot water at the sink before starting the dishwasher to ensure warm inlet water.
  • 2. Verify heating: During the wash, open the door briefly; if water is not hot, the heater or NTC sensor may be faulty.
  • 3. Clean turbidity sensor: If equipped, remove and clean the turbidity sensor in the sump to ensure accurate soil detection.
  • 4. Water pressure: Ensure adequate household water pressure and that the inlet filter is clean.

Long cycles with cold water usually indicate a heating system problem requiring service.
