Rust spots appearing on the interior or on dish racks.

Safety first: No electrical work required.

• Inspect racks: Check for chipped plastic coating on the racks. Use rack repair paint to seal small areas or replace racks if heavily corroded.
• Clean salt spills: If salt has spilled into the tub, clean thoroughly and run a rinse cycle to prevent corrosion.
• Avoid metal contact: Do not place non-dishwasher-safe metal items that can rust inside the machine.
