Rust/Discoloration on Dishes

Rust or discoloration on dishes - Salt, grounding, or unsuitable items

Beko · Dishwashers

What does Rust/Discoloration on Dishes mean?

Rust spots, discoloration, or general surface deterioration on metal items can be caused by salt leakage, improper electrical grounding, or washing items unsuitable for Dishwashers, such as low-quality metals.

Common Causes

  • Salt leakage around the salt filling hole.
  • Salty food remnants left on silverware for a long time.
  • Electric installation is not properly grounded.
  • Intensive cleansers like bleach were used.
  • Metal items used for unintended purposes (e.g., knives as can openers).

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    When adding salt, ensure it is not spilled around the filling hole. Tightly close the salt reservoir lid and run a prewash program to clear any spilled salt.

  2. 2

    Remove salty food remnants from silverware by pre-rinsing or wash immediately.

  3. 3

    Verify your Dishwasher's electrical installation is properly grounded by a qualified electrician.

  4. 4

    Do not wash dishes with bleach or use other intensive cleansers not recommended for Dishwashers.

  5. 5

    Avoid washing low-quality stainless steel or already corroded items in the Dishwasher to prevent further damage and cross-contamination.
