Tumble dryer drying cycle takes too long

Resolution

Issue:

  • Tumble dryer drying cycle takes too long

Applies to:

  • tumble dryer

Resolution:

1. Check whether the appliance is getting hot:

  • Firstly, clean the appliance and then start a timed cycle of at least 120 minutes with no load.
  • After one hour, open the door and check whether the drum is hot inside (with at least 20 minutes remaining on the display).
  • If the inside of the drum is hot, the heating system is working. In tumble dryers fitted with a heat pump, you can often also hear whooshing or sloshing noises from the appliance when it stops.
  • If the appliance is still not hot after an hour of the program, we recommend requesting a visit by a service engineer.

2. Check if your product is connected to a power outlet or grounded socket.

  • Your appliance must be connected to a power outlet or a grounded socket
  • If the appliance is not grounded, the measuring system will not work correctly and the appliance may ‘decide’ that the clothing is dry at the wrong time.
  • If your appliance is not grounded, there is a risk of electric shock.

3. Check if the ambient temperature is between 5°C and 35°C.

  • If the ambient temperature is too low or too high, the tumble dryer may not operate correctly.
  • Place the dryer in a room which has a suitable temperature.
  • If the dryer is located in a room, make sure that the temperature of the room is between 5°C and 35°C.
  • If the room temperature is not within this range, the tumble dryer may not operate correctly and will not heat up.
  • Heat the room in which the tumble dryer is situated until it reaches a suitable temperature, or move the dryer to another room which is at a suitable temperature.

4. Try adjusting the residual moisture level.

  • On many models, the residual moisture level can be adjusted.
  • You will find information on how to adjust this level in the user manual if your appliance has this function. 
  • Download user manual.
  • If you adjust the appliance to a line, the program cycle will be increased and the clothes will be drier by the time the cycle has finished.

5. Tumble dryers that are fitted with a heat pump give very gentle and energy-efficient drying at low temperature (max. 54°C), but the drying time will be somewhat longer than on appliances with high energy consumption. 

This is normal and not a malfunction in any way.

  • On these appliances, it may seem that the appliance is not heating for a long period of time at the start of a drying cycle. This is because all of the heat pump’s energy is used to heat and evaporate water/moisture in the clothing. Simply let the appliance run through the selected cycle until the desired drying results have been achieved according to the chosen cycle and options. 
  • Opening the door during a cycle to check on the clothing will extend the cycle by at least half an hour each time the door is opened. This is because the heat pump takes a long time to reach full working pressure in the heating system.
  • Some models have a quick-drying cycle with shorter drying time. You can use this cycle if you do not have time to wait for the normal drying cycle to finish. Using this program increases the energy consumption and noise level, as the heat pump will operate at full power and speed throughout the entire drying cycle.

6. Drying cushions, pillows and duvets:

  • First, check your user manual to see whether your machine is suitable for drying cushions, pillows and duvets.

Warning: If it is not suitable, there is a risk that the appliance may overheat and suffer damage.

  • If your appliance is suitable for drying cushions, pillow and duvets, set the program to dry the cushions/pillows/duvet in accordance with the user manual. 
  • For example, if your cushions are not completely dry inside after drying, you can use a cycle to finish the drying process. (More than 10 minutes’ duration, as the last 10 minutes of cycles consist of cooling without heat.)

7. Drying clothing from the washing line:

  • If you want to finish drying clothes that are almost dry, you can use a timed cycle (over 10 minutes’ duration, as the last 10 minutes of cycles consist of cooling without heat.)
  • Automatic drying cycles cannot be used for clothing which is only slightly damp.

8. Check if the filters and condenser are clean.

  • If the filters, condenser and/or heat exchanger are dirty, it may be the reason why the machine is not heating up.
  • See the user manual for information on how to clean and maintain your appliance. 
  • The filters may appear clean but still be blocked.
  • You can check the filters by holding them up against the light or under a tap and seeing whether the water can flow through them.
  • If no water passes through the filters, clean them and check them again.
  • If water will still not pass through the filters, replace them.
  • Filters and accessories are available via the Webshop.


If the above does not resolve the problem, request a visit by a service engineer.

To help you determine the exact nature of the problem, we recommend a visit by one of our authorized engineers to check the appliance and fix the problem.

Warning: We do not recommend using the product until the problem has been completely fixed. Unplug the product and do not plug it in again until you are certain that it is OK to do so.

Cause

1. If you find that your dryer is not drying satisfactorily, there are a number of possible causes. 

  • For best results with the lowest possible power consumption, the machine must be cleaned regularly and you should use the correct cycle and options in relation to the type of clothing you want to dry.
  • It is important that the clothing is sorted and dried according to clothing type when you use electronic cycles.
  • For some types of clothing, (e.g. with very thick seams) additional drying may be necessary after drying with a timed cycle (more than 10 minutes’ duration, because the last 10 minutes of the cycle consist of cooling without heat.)
