Beko Evaporator Icing / Defrost Failure

Dehumidifier runs but ice builds up heavily on the evaporator coil

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Room temperature too low, Faulty defrost sensor, Defrost control failure on PCB, Restricted airflow from dirty filter

Safety: Unplug the unit and allow ice to melt completely before working on it. Do not chip ice with sharp tools.

Steps:

1. Check room temperature: If below the recommended range, move the unit to a warmer room.
2. Clean filter and coils: Ensure good airflow through the evaporator.
3. Inspect defrost sensor: Verify the sensor is attached to the coil and wiring is intact. Replace if faulty.
4. If icing continues: The defrost algorithm on the PCB may be faulty, requiring board replacement.
