Why do rust, discoloration or surface deterioration occur on dishes in my Grundig GSF 41820 W?

Rust, discoloration, or surface deterioration on dishes in your Grundig Dishwasher can occur due to several reasons: salt leakage (avoid spilling salt and ensure the reservoir lid is tightly closed, running a prewash cycle to remove any spillage), salty food remnants left on dishes for a long time (remove dirt by prewash or wash dishes immediately), an ungrounded electrical installation (ensure the machine is connected to the grounding line), use of intensive cleansers like bleach (avoid washing dishes with bleach), using metal items for unintended purposes (do not misuse metal kitchen utensils), or cutlery made of low-quality stainless steel (avoid washing such items in the dishwasher).
