What should I do before using the washer dryer for the very first time?

Before first use, run the Drum Clean programme at 90°C without any laundry to remove residual test water from the factory inspection. Add approximately 1 litre of water into dispenser II along with standard detergent (half the recommended amount to prevent over-sudsing). Do not use woollens or mild detergents for this initial cycle. (Page 20)
