Rust spots appearing on the interior racks or tub components.

Safety first: No electrical work is required.

Steps:

• Inspect racks: Look for chipped or missing plastic coating on rack tines where rust is visible.
• Repair minor spots: Use a dishwasher-safe rack repair kit to coat small exposed areas.
• Replace severely rusted racks: If many tines are rusted or broken, replace the entire rack with a genuine Blomberg rack.

When to call a technician: Not usually necessary unless there is structural damage to the tub or mounting points.
