Rust spots or discoloration appearing on the interior stainless steel tub or racks.

Safety first: No electrical hazards, but avoid harsh chemicals without ventilation.

• Inspect racks: Look for chipped or missing plastic coating on rack tines. Rust can transfer to dishes.
• Remove foreign metals: Ensure no carbon steel items (e.g., non-stainless knives) are left in the dishwasher.
• Clean affected areas: Use a non-abrasive cleaner to remove surface rust from the tub.

Severely rusted racks should be replaced with new upper or lower rack assemblies to prevent further staining.
