Defrost Function

If the device is operated in an environment with low temperatures, frost may form inside the device. To ensure perfect operation, the air dehumidifier features a defrost function. If the temperature is between 5°C and 16°C, the device automatically starts with the defrost function for 10 minutes. The ON/OFF symbol 17 flashes on the display whilst the defrost function is running. Once the 10 minutes have elapsed, the device continues running normally for 60 minutes.

Emptying the Water Tank

If the water tank 1 is full, the water level symbol 20 will light up red and the device will automatically stop running. An acoustic signal will sound (except in sleep mode) and the message “FL” will appear on the display.

CLEANING, CARE AND MAINTENANCE

Before performing any cleaning or maintenance work, always ensure that the mains plug of the device has been properly disconnected!
Always store the device in its original packaging. Only store the device in an upright position. Do not place any objects on the device.
Store the device in a well-ventilated room that measures at least 4 m².
Store the device in dry conditions and protected from frost and heat.
Clean the device and allow it to dry fully before putting it into storage.
The device must be stored in a room where there are no permanent sources of heat (e.g. naked flames, a running gas device or a running electric heater).

This device contains R-290 refrigerant. However, the quantity of refrigerant is less than 1 kg and it is kept in a sealed cooling circuit. Maintenance may only be carried out by trained technicians or Beurer service personnel. The device does not need to be refilled with refrigerant provided that it is used correctly and the coolant circuit is undamaged. Regular cleaning is a prerequisite for hygienic and fault-free operation. Always fully empty and thoroughly clean the water tank of the air dehumidifier if the device has not been used for more than 3 days. A lack of cleaning and hygiene can cause bacteria, algae and fungi to form in the water.

Cleaning the Air Filter

We recommend cleaning the air filter 6 every 14 days as dust can collect there and restrict the airflow. Do not operate the device without the air filter 6 installed.

Remove the air filter 6.
If it is slightly dirty, use the brush of a vacuum cleaner to carefully remove the dust residue from the screen.
If it is very dirty, soak the air filter 6 in warm water at a temperature of approx. 40°C. Then rinse it carefully with a neutral cleaning product.

Faqs

How do I set up the beurer Air Dehumidifier LE 250 for the first time?

Unpack the unit, remove transport tape, and place the beurer Air Dehumidifier LE 250 on a flat surface with at least 20–30 cm clearance for airflow; insert the washable pre-filter and the 4.0 L water tank, then plug into a grounded outlet (220–240 V) and switch on. Use the display to select Automatic or a target humidity between 30–80% or choose Laundry or Night mode for specific use cases. Follow safety and manual instructions for external condensate drain if continuous drainage is needed.

What should I do if my beurer Air Dehumidifier LE 250 is not extracting water or performance seems low?

Check room temperature and humidity—below about 5–16°C the unit may run defrost cycles and reduce output—and ensure the air intake/outlet are unobstructed; clean the washable pre-filter and confirm the tank isn't full or misaligned (overflow protection halts operation). For continuous use, attach the condensate hose and verify it isn’t kinked. If issues persist, reset the unit by unplugging for 5 minutes and consult the manual or service center.

How do the Automatic, Laundry and Night modes work on the beurer Air Dehumidifier LE 250?

Automatic mode keeps relative humidity in the optimum 45–55% range by adjusting fan and compressor operation; Laundry mode runs at maximum output to speed drying of clothes; Night mode reduces fan noise and turns off bright display lights for quiet operation. Use Automatic for everyday control, Laundry when drying wet items, and Night for bedroom use to balance performance and comfort.

Can I use the beurer Air Dehumidifier LE 250 in a basement or for water-damage restoration?

Yes—the beurer Air Dehumidifier LE 250 is designed for long-term dehumidification and is suitable for basements and water-damage situations thanks to up to 20 L/24 h capacity and an external condensate drain option for continuous operation; position it centrally, run in Continuous or Automatic mode, and use the hose to direct water to a drain for extended unattended use.

What maintenance does the beurer Air Dehumidifier LE 250 require and how often?

Regular maintenance includes emptying and rinsing the 4.0 L tank after use, washing the removable pre-filter every 2–4 weeks (or more often in dusty environments), and checking the condensate hose and overflow protection. Inspect and clean air inlets/outlets monthly; arrange professional servicing if refrigerant or compressor faults appear. Proper maintenance preserves features like automatic defrost and laundry drying performance.

How can I optimize energy efficiency and performance for my beurer Air Dehumidifier LE 250?

Set a realistic target humidity (45–55% in Automatic) rather than lowest setting, use Laundry mode only when needed, close windows and doors to the area being dehumidified, place unit within recommended room size (up to ~60 m²), and use the external condensate drain for long runs to avoid frequent tank handling. These steps reduce runtime and improve energy efficiency while maintaining optimal moisture control.

What common warning lights or error symptoms should I watch for on the beurer Air Dehumidifier LE 250, and how do I respond?

A full-tank indicator or automatic shutoff means the 4.0 L tank must be emptied and reinserted; a flashing ON/OFF symbol usually indicates the automatic defrost cycle at low temperatures (5–16°C) and requires waiting until it finishes; blocked-air or filter warnings mean clean the washable pre-filter. For persistent error codes, consult the manual for code-specific fixes or contact Beurer support for service.

Is the beurer Air Dehumidifier LE 250 compatible with continuous drainage and what are the installation requirements?

Yes—the beurer Air Dehumidifier LE 250 includes a connection for an external condensate drain and typically supplies a drain hose; install the hose with a downward slope to a floor drain or bucket, ensure no kinks or backflow, and secure the connection to the unit. Continuous drainage is recommended for long-term dehumidification, basements, or water-damage use to avoid frequent emptying of the 4 L tank.
