My Beko tumble dryer beeps five times when I press a button or turn the programme selection knob. Is this normal?

This means that the child lock on your tumble dryer is active. 

To deactivate the child lock, press the sound notification/buzzer button and the start / pause / cancel / end duration button simultaneously for three seconds while any programme is running. The lights on the buttons will flash while you do so. 

You can also switch the programme selection knob to the On/Off position while no programme is running to deactivate the lock. 

The procedure to activate/deactivate the child lock may vary depending on your model. If the procedures described above do not work, consult your user manual. If you’re having trouble finding your manual, download it here using your product’s model number.
