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

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

• Adjust detergent: Use a high-quality detergent formulated for hard water and follow dosage recommendations.
• Use rinse aid: Ensure the rinse aid dispenser is filled and set to a higher dosage.
• Run cleaning cycle: Run an empty hot cycle with a dishwasher cleaner or white vinegar (in a dishwasher-safe cup on the top rack) to remove existing deposits.
• Consider softening: In very hard water areas, consider installing a whole-house or under-sink water softener.
