The appliance washes lint, which builds up onto the surface of the condenser, automatically using water that is condensed from the clothes during operation. However, you can clean the condenser manually if you want to clean it more often.
Remove all of the clothes from the appliance.
Pull out the water container and empty the water container.
Pour 1 litre of clean water slowly into the entrance of the water container compartment. Then refit the empty water container into the compartment.
Do not pour the water quickly as it will spill out.
Pouring more that 1.5 litres of water into the compartment will cause water to leak back out.

Turn on the appliance.
Press and hold the Condenser Care button for 3 seconds.
Press the Start/Pause button to start the cleaning of the condenser.
The cleaning of the condenser proceeds for 1 hour.
Empty the water container after the cleaning is finished.
When the optional drain hose is installed, there is no need to empty the water container.
Open the dryer's door to provide the appliance with enough air circulation for more thorough drying of the tub after the cleaning has ended.
For safety reasons, do not allow children or animals to enter the appliance. It may cause damage or injury.
