What Does Error E2 Mean?

The Daewoo dehumidifier E2 error indicates a malfunction in the humidity sensor or humidity sensing circuit. This leads to erratic display readings and can prevent the unit from operating correctly, often resulting in continuous dehumidification or inaccurate humidity readings. Addressing this issue typically involves inspecting and testing the humidity sensor and its connections.

Common Symptoms:

  • Unit displays E2 on digital panel instead of normal humidity value
  • Unit may switch to continuous dehumidification operation instead of normal control
  • Humidity reading may be inaccurate, unit may not respond correctly to set humidity

Possible Causes

  • Humidity sensor malfunction or faulty humidity sensing circuit (medium)

How to Fix Error E2

DIY Fix Basic inspection and reset

  1. Power off the dehumidifier and unplug it from the outlet.
  2. Wait 5–10 minutes, then plug it back in and power on to see if the code clears.
  3. Ensure the unit’s water tank is correctly seated and not triggering other interlocks.
  4. Clean the exterior intake grills to avoid dust interfering with internal sensors.

Technician Only Inspect and test humidity sensor circuit

  1. Disconnect power and open the dehumidifier enclosure per service procedures.
  2. Locate the humidity sensor and inspect wiring for corrosion, loose connectors, or damage.
  3. Measure sensor output or resistance with a multimeter to verify within expected range per component specification.
  4. Replace the humidity sensor or repair the harness if out of specification.
  5. Test the control board humidity input circuit for continuity and correct voltages.

Parts needed: Humidity sensor, Sensor harness/connectors, Control board (if sensor circuit damaged)

🛑 When to Call a Pro:
  • If the error persists after power cycling and basic checks
  • If internal diagnostics suggest sensor reading outside of expected range
  • If there is visible damage to wiring or PCB that the user cannot safely address
