Below are instructions for how to take out the heat exchanger and clean it.
1. Gently press the top part of the outer cover (A) to open.
2. Unlock the levers (B).
3. Remove the inner cover (C).
4. Clean the heat exchanger with the cleaning brush provided.
5. Take care to brush up and down in a vertical motion. Do not bend or damage the heat exchanger fins when cleaning (especially if using a vacuum cleaner with a brush attachment) as this may lead to a decrease in drying performance.
6. Clean the inner cover with a smooth damp cloth.
7. Reinsert the inner cover to its original position and the lock the inner cover by using the levers.
8. Close the outer cover and make sure the levers are locked.

Some dryers have an indicator which lights up or flashes during the cycle if the heat exchanger needs to be cleaned. Other machines have a buzzer that sounds after 25 uses until it is cleaned. Opening the inner cover or turning off the power plug will stop the buzzer sounding when the heat exchanger has not been cleaned. We recommend cleaning the heat exchanger in your dryer after every 25 cycles or at least once a month for the best drying results.
