What Does Error HI Mean?

The GE dehumidifier HI error code indicates that the unit has detected humidity levels exceeding its measurable range or a fault with the humidity sensor. Symptoms include the display showing 'HI' instead of a numeric value, the unit running continuously without achieving the set humidity level, and this occurring even when room humidity seems normal. Possible causes include actual room humidity being excessively high or issues with the humidity sensor itself, such as contamination or disconnection.

Common Symptoms:

  • Display shows "HI" instead of a numeric humidity value
  • Unit continues to run without reaching set humidity
  • Occurs even when actual room humidity appears normal

Possible Causes

  • Actual room humidity extremely high beyond sensor range (medium)
  • Humidity sensor contamination, failure, or disconnection (medium)

How to Fix Error HI

DIY Fix Check actual humidity and environment

  1. Use a separate hygrometer to measure room humidity
  2. If humidity is extremely high, allow dehumidifier to run and reduce humidity
  3. Ensure area has adequate ventilation

Technician Only Inspect and service humidity sensor and wiring

  1. Unplug the unit and access the control panel
  2. Inspect humidity sensor connector and wiring harness for secure connection
  3. Clean around or replace humidity sensor if contaminated or faulty
  4. Test with a known-good sensor if available

Parts needed: Humidity sensor module, Wiring harness/connectors

🛑 When to Call a Pro:
  • If after sensor replacement and humidity verification the HI code persists
  • If there are additional error indicators or unit performance issues accompany the HI display
