Why are my dishes coming out wet after the cycle, and how do I fix it?

Dishes may come out wet if the selected programme does not have a drying phase or has a drying phase with low temperature, if the rinse aid dispenser is empty, or if the quality of the rinse aid is the cause. For better drying results, the manual also recommends keeping the appliance door ajar for a few minutes before removing the dishes. (Page 16)
