Possible Causes

Empty rinse aid dispenser, Incorrect program selection, Faulty drying fan or heater, Plastic items retaining water

How to Fix / Troubleshooting

Safety: Disconnect power before accessing internal electrical parts.

Check rinse aid: Ensure the rinse aid dispenser is filled and the dosage setting is appropriate for your water hardness.
Use suitable program: Select a program with a full drying phase (e.g., Eco or Intensive) rather than quick or rinse-only cycles.
Load correctly: Angle dishes so water can run off, and avoid nesting bowls. Plastic items naturally dry less well.
Check drying system: If drying is very poor, test the heater and, on models with active drying, the fan. Replace faulty components as needed.
