White film or cloudy residue on dishes and glassware.

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

• Check water hardness: If you have hard water, use a detergent formulated for hard water and always use rinse aid.
• Adjust detergent amount: Use the recommended amount; too much can leave residue.
• Increase water temperature: Ensure your water heater is set to at least 120°F (49°C).
• Clean existing film: Run a cycle with dishwasher cleaner or white vinegar (no dishes) to remove mineral buildup.
