What Does Error HI Mean?

The Daewoo dehumidifier HI error indicates a high humidity detection issue, which may occur when environmental conditions exceed normal ranges. This can cause the unit to continuously run without responding to actual humidity changes. The display will show 'HI' prominently, suggesting that the humidity sensor may be experiencing an over-range condition due to excessively high humidity or temperature. It's important to check the placement of the unit and ensure it is not exposed to water or condensation.

Common Symptoms:

  • Display shows 'HI' prominently on the unit’s display
  • Dehumidifier continues running or does not respond to normal humidity changes
  • HI display persists regardless of actual room humidity

Possible Causes

  • Humidity Sensor
  • Dirty Air Filter

How to Fix Error HI

DIY Fix Check environmental conditions and basic settings

  1. Ensure the dehumidifier is placed in a room with typical humidity levels—extremely high humidity may trigger an over‑range indication (general behavior in some dehumidifiers).
  2. Move the unit to a different location in the room with better airflow.
  3. Verify the device is not exposed to direct water spray or condensation on the sensor area.

Technician Only Inspect and clean humidity sensor and wiring

  1. Disconnect power and open the housing to access the humidity sensor.
  2. Visually inspect the sensor and wiring harness for condensation, corrosion, or damage.
  3. Clean the sensor gently if contaminated; reassemble and test.
  4. If 'HI' persists and environmental causes have been ruled out, consider replacing the humidity sensor module.

Parts needed: humidity sensor module, wire harness
