Original Replacement Float for WDH-520HB / Akto 521

Original replacement float for the dehumidifier WDH-520HB or Akto 521. The float monitors the water level in the condensate tank and ensures that the unit switches off reliably when the water tank is full.

Important Model Comparison:
This replacement float is intended for the older generations of the WDH-520HB / Akto 521. This version features a short pin without a magnet. Please be sure to compare your existing float with the product images before ordering.

Original float for the WDH-520HB

The condensate tank of a dehumidifier is continuously filled with water during operation. The float detects the rising water level and triggers the automatic shut-off of the device when the tank is full. It is therefore an important component for safe operation and protection against the water tank overflowing.

If the existing float is damaged, dirty, or no longer functional, replacing it can restore reliable tank shut-off.

Your Benefits

  • Original spare part: Suitable for the older generation of WDH-520HB / Akto 521.
  • Reliable tank shut-off: Detects the water level in the condensate tank and supports automatic shut-off when the tank is full.
  • Short pin without magnet: Specific version for older device series.
  • Easy installation: The float can be replaced without special tools.
  • Robust plastic: Easy to maintain and easy to wash.
  • CE and EMC compliant: Original spare part in accordance with the stated compliance features.

Suitable for WDH-520HB / Akto 521

This float is explicitly intended for the older generation of the WDH-520HB / Akto 521. Since different float versions can be used within the various device series, comparing it with the existing old part is particularly important.

Please check before ordering:
Your existing float should match the model shown in the product images and have a short pin without a magnet. This spare part may not be suitable if your version is different.

Easy Replacement

The original float is easy to replace. As a rule, no special tools are required for this. After insertion, you should check whether the float can move freely and is positioned correctly in the condensate tank.

Ensure that the float is not blocked by deposits, dirt, or foreign objects. Free movement is important for the water level detection to function reliably.

Frequently Asked Questions about the replacement float

Which device is this float suitable for?

The float is intended for the WDH-520HB / Akto 521 of the older generation.

How do I know if the float fits my device?

Compare your existing float with the product images. It is particularly important that it is the version with a short pin without a magnet.

What does the float do in the dehumidifier?

The float monitors the water level in the condensate tank. When the tank is full, it triggers the shut-off of the dehumidifier.

Can I replace the float myself?

Yes. The replacement is generally easy and does not require any special tools.

Does this float have a magnet?

No. This spare part has a short pin without a magnet and is therefore designed for the corresponding older generation of devices.

What happens if the float no longer works?

Incorrect water level detection can cause the automatic shut-off to stop working reliably when the condensate tank is full. A damaged float should therefore be replaced.

Can the float be cleaned?

Yes. The plastic float can be cleaned carefully and cleared of deposits. It should then be able to move freely.

What is included in the scope of delivery?

The delivery includes 1 × Original replacement float for the WDH-520HB / Akto 521 of the corresponding older generation.
