Sounds
In the initial drying stage or during drying, the compressor and the heat pump cause noise; this,
however, does not affect the tumble dryer operation.
Humming sound: this is the sound of the compressor unit. The level of noise depends on the
program and the drying stage.
Whirring sound: from time to time, the compressor unit is ventilated.
Pumping sound: the pump is pumping the condensate into the condensate tank.
Clicking sound: clicking noise is caused by automatic cleaning of the heat exchanger
(compressor).
Rattling sound: can be heard during drying if laundry has any hard parts (buttons, zippers etc.).
