Troubleshooting and error codes

Faults Cause/remedy
The appliance will not start. Check the mains plug and the fuses.
Creasing.
  • Load exceeded or incorrect programme selected for a type of fabric. All the required information can be found in the programme table.
  • Remove laundry from the drum as soon as the drying programme has finished. Creasing occurs when clothing is left in the drum.
Water is leaking out.
  • The appliance may be positioned at an angle. Level the appliance.
  • In the base unit, make sure that:
    • The heat exchanger cover is properly locked.
    • There is no dirt or debris on the heat exchanger cover's seal.
  • If the optional drain hose* is installed, make sure that the drain hose is correctly connected.
The programme does not start Make sure that:
  • The door is closed
  • The 3 sec (Child lock) has been deactivated
  • You have pressed ▷ (Start/Pause)
Note: If the programme has been delayed by setting ☺ (Ready in), the programme starts at a later point.
Programme duration displayed changes as drying progresses. Not a fault. The moisture sensor measures the residual moisture in the laundry and adjusts the programme duration (with the exception of timed programmes).
Laundry is not dried properly or is still too damp.
  • After the programme has ended, warm laundry feels damper than it actually is. Spread out the laundry and let it cool down.
  • Adjust the drying time or increase the degree of dryness. This will extend the drying time but the temperature will remain the same.
  • Select a timed programme to add extra drying time for laundry that is still damp.
  • Select a timed programme for a small load.
  • Do not exceed the maximum load for a programme.
  • Clean the moisture sensor in the drum. The sensor may become covered in a fine layer of limescale or detergent and care product residue, which then impairs its performance.
  • Drying has been interrupted as a result of a power cut, because the condensation container is full or because the maximum drying time has been exceeded.
Note: See also the laundry tips.
Drying is taking too long.
  • The appliance may have fluff in it. This will increase the required drying time. Remove the fluff.
  • The heat exchanger may have fluff in it. Run the basic appliance care programme.
  • If the air inlet on the appliance is blocked or not fully open, this may increase the drying time. Make sure that the air inlet remains unobstructed.
  • If the ambient temperature is lower than 15 °C or higher than 30 °C, this may increase the drying time.
  • Inadequate air circulation in the room may increase the drying time. Make sure the room is adequately ventilated.
Unpleasant odour in the appliance Run the intensive appliance care programme.
I am unable to connect to my home network.
  • Wi-Fi is switched off. To connect to your home network, switch on Wi-Fi. must appear on the display.
  • Wi-Fi is switched on but a connection to your home network cannot be established. Check whether your home network is available or try to connect to your home network again.
Home Connect is not working. You can find solutions to problems with Home Connect at www.home-connect.com. The availability of the Home Connect functionality depends on the availability of the Home Connect Services (e.g. provision of the app) in your country. Home Connect Services are not available in every country – for further information please check: www.home-connect.com.
Humidity in the room is increasing. Make sure the room is sufficiently ventilated.
Unusual noises when drying. When drying is in progress, the pump and compressor generate noise when operating normally. This does not indicate that the appliance is malfunctioning.
The appliance feels cold despite drying. Not a fault. The appliance can dry effectively at low temperatures using a heat pump.
Drying programme is stopped. If the drying programme is stopped due to a power failure, restart the programme or remove the laundry and spread it out.
Residual water in the condensation container despite the appliance being connected to the drain hose*. If the optional drain hose is installed, residual water remains in the condensation container due to the appliance's self-cleaning function.
