Dishwasher runs for an unusually long time; cycles seem to never finish.

Safety first: Be cautious of hot steam when checking mid-cycle.

• 1. Check water temperature: Run hot water at the sink before starting the dishwasher to ensure hot water enters immediately.
• 2. Verify heater operation: During the wash, open the door briefly and feel if the interior is hot. If not, test the heater and NTC sensor.
• 3. Clean sensors and filters: Dirty filters and turbidity sensors can cause the control to think water is still dirty, extending the cycle. Clean thoroughly.
• 4. Use appropriate program: Eco programs are designed to run longer; select a normal or quick cycle if shorter time is desired.
• 5. Control board check: If cycles are excessively long and not consistent with program specs, the control board may be faulty.

Warning: Do not interrupt cycles repeatedly; this can leave detergent residue and poor results.
