Use

Do not exceed the amount of laundry specified in the user manual.
Similar fabrics will take about the same amount of time to dry, which means that all your clothes will be dry at the same time. If you put different types of fabric in the dryer, the machine will work part of the time to dry a few different garments, which is not energy efficient.
It is not advisable to add wet clothes in the middle of the drying cycle. Water from the wet clothes will soak into the dry clothes, meaning it will take longer and use more energy to dry all your laundry.
If you have a lot of laundry, it is better to dry it without long intervals between cycles. This way, you can use the heat that is already present in the tumble dryer.
If you plan to tumble dry your laundry, use a higher spin speed during washing. Putting wet laundry in the tumble dryer will increase the drying time, increase energy consumption and put unnecessary strain on the appliance. Adding dryer balls can reduce cycle times and, consequently, save electricity. During washing, the balls create free space that allows the warm air to circulate. They also reduce the static energy that is generated during drying.
Clean the lint filter after each drying cycle; this will ensure more efficient and faster drying.
Do not use fabric softener when washing clothes. The tumble dryer automatically makes your laundry soft; furthermore, the softener can damage the humidity sensors and cause unwanted odours during drying.
If necessary, buy special accessories such as baskets and/or racks so you can also dry shoes and clothes that are sensitive to the drying process.
