Dishwasher runs but does not dry dishes; items are wet and cool at the end of the cycle.

Safety first: Disconnect power before accessing heater or fan components.

• Check program selection: Ensure you are using a program with active drying, not a quick or eco cycle with limited drying.
• Verify rinse aid: Fill the rinse aid dispenser and adjust the dosage to improve drying.
• Check for heat: At the end of a hot program, open the door carefully. If the interior is cold, suspect a heating issue (see heating-related faults and codes).
• Inspect drying fan: If your Grundig model has an active drying fan, listen for its operation. If silent, access the fan via the door or top panel and test/replace as needed.
• Load correctly: Angle dishes to allow water to run off and avoid large flat surfaces that trap water.
