Dishwasher leaves a cloudy film or rainbow sheen on glassware, sometimes with etching.

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

• Adjust detergent: Reduce the amount of detergent used, especially if water is soft.
• Check water softener: Ensure the softener is not set too high for your water hardness.
• Adjust rinse aid: Reduce the rinse aid dosage if streaking or rainbow sheen is present.
• Use glass protection program: If your CDA model has a delicate or glass cycle, use it for fine glassware.
• Test with different detergent: Try a different brand formulated to protect glass.
