Tumble dryer's drying results are poor and laundry is damp after drying

If drying results are poor and laundry is damp after drying, refer to the suggestions below for step by step instructions.

Tumble Dryer, including (Tumble dryer with heat pump an Condenser tumble dryer):

Getting the best drying results:

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

  • For best results with the lowest possible energy consumption, the machine must be cleaned regularly and you should use the correct cycle and options in relation to the type of clothing you wish 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).

Check whether the appliance is getting hot:

Before you book an engineer, it is important to check if the appliance’s heating system is working. 

  • 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. (Report error code: JN).

Is your product connected to a power outlet or grounded socket?

Your appliance must be connected to a power outlet or an 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.

Is the ambient temperature 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.

Have you tried 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. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).
  • 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.

Tumble dryer fitted with heat pump:
  • 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 a 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.

Drying cushions, pillows and duvets:

First, check your user manual to see whether your machine is suitable for drying cushions, pillows and duvets. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).

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. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).

  • 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.)

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 are only slightly damp.

Is the DEMO function on your product enabled?

The DEMO function is a display function for retail stores.

  • It is used to demonstrate the product without having to go through a normal cycle.
  • The display function is indicated by the letters ‘DEM’ on the display or on a display for rapid countdown.

Disabling the DEMO function:

  • The demo function will remain enabled even after the dryer has been switched off using the On/Off button.
  • When the On/Off button is pressed to restart the appliance, the display will show DEM for a few seconds in order to enable the demo function to be used in a showroom.
  • To exit the demo function, switch off the power supply to the dryer, wait about a minute and then switch it on again.

Are you using fabric softener during the wash cycle before you use the dryer?

We recommend that you do not use a fabric softener during a wash cycle.

Cleaning the drum:

  • When you use fabric conditioner in a wash cycle, a film will probably form on the inside of the drum, the drum ribs and the measuring sensor.
  • This film will interfere with moisture measurement, making the dryer ‘think’ that the clothing is dry.
  • The drum can be cleaned with a cloth and vinegar.
  • Some models have the sensors located inside the machine on the plastic tab at the bottom, behind the door opening.

Have you filled the drum sufficiently?

When you use electronic cycles, the drum will detect whether the clothing is dry.

  • When the drum is filled with a small amount of clothing, it is sometimes unable to detect the clothing and will then end the cycle.
  • For very small amounts of clothing, it is recommended that you use time-based drying.

Filling enough laundry:

  • When you use a pre-programmed cycle, you must ensure that the drum has sufficient capacity.
  • If there is not enough clothing in the drum, the drum may be unable to detect it and the tumble dryer will end the cycle.
  • The tumble dryer is best used at the maximum capacity of the chosen cycle.
  • This is the most efficient way to use the tumble dryer’s energy.

Did you select a timed cycle?

Try a pre-programmed standard drying cycle instead of time-based drying

  • When you use a timed cycle, the time you select is the duration of the cycle.
  • For example, when you a 20-minute program, the dryer will stop after 20 minutes, possibly resulting in poor drying results.
  • For best results, use a pre-programmed cycle.
  • The dryer automatically detects when the laundry is dry.

Is the “water tank full” indicator lit?

The appliance will stop the cycle if the water tank is full.

  • Empty the tank and restart the cycle.

Is your product connected to an external drain?

The machine will stop the cycle if there is a problem with the drain

  • Check that it has been installed correctly and that the hose is not twisted or kinked.

Warning: Do not suspend the basket any higher than 1m and shorten the drain hose as necessary, so that no loops of more than 0.5 m form as shown in the figure.

Are the filters clean? Is the machine clean?

If the filters, condenser and/or heat exchanger are dirty, it may be the reason why the machine is not heating up.

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. (You can visit our Webshop by clicking on the link below).
Examples of cleaning different types of tumble dryer:
