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

Safety first: No electrical work is required for this issue; focus on water quality and detergents.

Step-by-step checks:

• Rinse aid level: Fill the rinse aid dispenser and set the dosage to a higher setting.
• Detergent choice: Use a high-quality detergent formulated for hard water. Avoid mixing powder and pods.
• Water hardness: If you have very hard water, consider installing a water softener or using dishwasher additives designed for hard water.
• Cleaning cycle: Run an empty hot cycle with dishwasher cleaner to remove internal mineral buildup.
• Test glasses: Soak a cloudy glass in vinegar. If the film dissolves, it is mineral deposit; if not, it may be permanent etching from too high temperature or detergent overdose.

Warning: Overdosing detergent can also cause etching; adjust gradually.
