Dishwasher displays unusually long cycle times without showing an error code.

Safety first: Disconnect power before accessing internal components.

• Check water temperature: Run the hot tap until water is hot before starting the dishwasher to reduce heating time.
• Clean sensors and sump: Remove filters and clean the sump and any visible sensor windows to ensure accurate soil detection.
• Descale the machine: Run an empty hot cycle with a descaling agent to remove limescale from the heater and internal surfaces.
• Check heater performance: If cycles remain excessively long, test the heater and NTC sensor as described in heating circuit diagnostics.
