How to Fix / Troubleshooting

Safety first: Be cautious of hot steam when opening the door mid-cycle.

  • Check water temperature: Run hot water at the sink before starting the dishwasher to ensure hot water enters the machine.
  • Observe heating: During the wash phase, open the door briefly (after pausing) to see if water is hot. If not, investigate heater faults.
  • Clean sensors: Run a cleaning cycle with dishwasher cleaner to remove grease that can affect sensors.

If cycles remain excessively long, a technician should test the heater, NTC sensor, and turbidity/soil sensor if fitted.
