GE Dehumidifier E6 Error Code: Humidity Sensor Fault

Quick Answer

GE dehumidifier E6 means the humidity sensor is reading out of range or has an open/short circuit. GE dehumidifiers use a capacitive humidity sensor that measures relative humidity to determine when the target has been reached and the compressor should cycle off. E6 triggers when this sensor fails.

GE dehumidifier E6 means the humidity sensor is reading out of range or has an open/short circuit. GE dehumidifiers use a capacitive humidity sensor that measures relative humidity to determine when the target has been reached and the compressor should cycle off. E6 triggers when this sensor fails. Unlike the temperature sensor (which is an NTC thermistor), the humidity sensor is a capacitive type that cannot be easily tested with a standard multimeter. Before replacing: unplug the dehumidifier for 1 hour in a dry room, then plug back in. Humidity sensors can temporarily fail in extremely high humidity conditions (above 90% RH) and recover once conditions normalize. If E6 persists after the 1-hour dry reset, the sensor has permanently failed.

What Does the E6 Code Mean?

E6 = humidity sensor failed. Try 1-hour unplug in dry room first (sensor recovers from extreme humidity sometimes). If persistent, humidity sensor needs replacement. Cannot test with standard multimeter (capacitive type).

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Humidity sensor saturated from extreme humidity40%
Humidity sensor element failed24%
Sensor connector corroded14%
Sensor exposed to water splash12%
Control board humidity input fault10%

Symptoms You May Notice

  • E6 on display
  • Dehumidifier runs constantly (cannot sense target humidity)
  • Dehumidifier will not start
  • Humidity reading shows 0 or error

Can you reset a Ge dehumidifier to clear the E6 code?

Unplug for 30 seconds. Plug back in. If error persists, follow the specific diagnostic steps.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Unplug the dehumidifier

Unplug the dehumidifier. Move it to the driest room available. Let it sit unplugged for 1 hour. The humidity sensor may recover from temporary saturation.

2

Access the humidity sensor (behind the front panel near the

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Can extreme humidity damage the GE humidity sensor?
Yes. Sustained exposure above 90% RH can saturate a capacitive humidity sensor. The sensor is designed for 20-80% RH measurement range. In very damp basements or after flooding, the sensor may temporarily read incorrectly until it dries out.
E6 but dehumidifier still removes water. Should I worry?
If the dehumidifier runs but cannot read humidity, it may run continuously (never reaching what it thinks is the target). This wastes energy and can over-dry the room. Fix E6 for proper operation.
GE dehumidifier E6 reset?
Unplug for 1 hour in a dry room. If E6 clears, the sensor recovered. If not, the sensor needs replacement. There is no button-based reset for E6.
