Dishwasher runs for a very long time or never seems to finish the cycle.

Safety first: No internal work is required initially; keep the door closed during operation.

• 1. Check water temperature: Run hot water at the kitchen tap until it is hot before starting the Hisense dishwasher. This reduces fill time and heating load.
• 2. Clean sensors and filters: Clean the turbidity sensor window (if accessible), filters, and spray arms to ensure accurate soil detection and efficient washing.
• 3. Observe heating: During the wash, carefully open the door briefly (after pausing) to check if the water is hot. If not, the heater may be failing, causing the control to extend the cycle.
• 4. Run a cleaning cycle: Use a dishwasher cleaner to remove internal buildup that can affect sensors.
• 5. If still excessive: A failing heater or control board may require professional diagnosis and replacement.
