White film or cloudy residue on glasses and dishes after washing.

Safety first: No electrical work is required for this issue.

Steps:

• Check salt level: Ensure the water softener salt reservoir is filled with dishwasher salt and the cap is tight.
• Adjust hardness setting: Set the dishwasher's water hardness level according to your local water hardness (see user manual).
• Use proper detergent: Use high-quality detergent and avoid overfilling the dispenser.
• Increase rinse aid: Adjust the rinse aid dosage to a higher setting.
• Run descaling cycle: Use a dishwasher descaler on a hot program to remove existing limescale.

When to call a technician: If the built-in softener is not regenerating properly despite correct settings, professional service may be needed.
