Dishwasher interior is rusty or shows orange/brown stains.

Safety first: No electrical work required.

Step-by-step checks:

• Inspect racks and baskets: Look for chipped plastic coating on racks and cutlery baskets. Replace or repair with rack repair paint to prevent further rust.
• Remove rusty items: Do not wash non-stainless tools or rusted pans in the dishwasher.
• Clean stains: Use a dishwasher-safe descaler or citric acid cleaner on a hot empty cycle to remove rust stains.
• Water quality: If your water has high iron content, consider a whole-house filter or specific iron filter.

Addressing the source of rust will prevent new staining.
