Condensation will form in the appliance as it dries the laundry. Condensation usually occurs as soon as water vapor is cooled below the dew point. In the process of condensation, a gaseous substance changes to a liquid state. In the case of water vapor, the common term is condensate water. It is the main cause of moisture damage in buildings or on devices. To avoid this kind of damage, it is important to drain condensate water regularly.
Emptying the condensate container of your dryer:
If there is not a drain hose connected to the appliance, the condensation water from the appliance will run into the condensation container. In this case, you will need to empty the condensation container every time the dryer finishes drying the laundry, and also if it becomes full before drying is complete. Only the correct drainage of the condensate water ensures durability and prevents long-term damage. Three simple steps are enough to properly drain the condensate water from your dryer.
