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.

Here's what I usually see when I show up to one of these calls: the unit's been sitting in a wet basement all summer and the sensor's basically waterlogged. It won't always be a dead sensor either. Sometimes it just needs to dry out completely. But if you ignore it and keep running the machine, you're risking a fried compressor because the unit doesn't know when to shut off. Fix it now, not later.

What Does the E6 Code Mean?

E6 is almost never the control board, so don't go spending $80 on that first. It's usually a fouled sensor or a corroded connector pin. I replaced three of these sensors last month alone, all in basement units that had been running through a wet spring. Since they're capacitive sensors, you can't just probe them with a multimeter and get a clear pass/fail reading. You're basically doing process of elimination: dry it out, clean the contacts, and if it's still throwing E6, swap the sensor.

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 blinks on the display and the unit won't start at all, or shuts down within a few seconds of powering on.
The dehumidifier runs constantly without ever cycling off, even after the bucket fills up, because it can't sense that the room humidity has dropped.
Humidity percentage on the display is frozen at 0%, or jumps between 0% and 100% randomly like it's just guessing.
Fan runs but the compressor never kicks on, or you hear it clicking like it's trying to start and then cutting out.
Unit starts fine in a dry room but throws E6 as soon as you bring it back down to the basement.

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

There's no button sequence for E6. It's a hard fault that won't clear until the root cause is fixed. Unplug the unit completely and leave it for at least 60 minutes in a dry area. When you plug it back in, let it run in that dry spot for 15-20 minutes before bringing it back to a humid space. If the code's gone, great. If it comes back within a few minutes of running, the sensor needs to be replaced.

Frequently Asked Questions

Can extreme humidity damage the GE humidity sensor?

Yeah, it can. If the air's been sitting at 90%+ for a long time, like during a basement flood, the capacitive layers inside the sensor literally absorb moisture. Sometimes it's temporary and the sensor recovers after drying out for a day. But if it stays wet for days on end, those layers can delaminate and the sensor's gone for good. I've pulled sensors out of flood-damaged units that looked totally fine on the outside but were completely dead when tested.

E6 but the dehumidifier is still pulling water. Should I worry?

Honestly, yeah. It might seem like it's working fine, but without a functioning humidity sensor the unit doesn't know when to stop. So it runs 24/7, which burns through electricity and puts serious wear on the compressor. The other problem is the defrost cycle, it relies on sensor feedback too. Without it, the evaporator coil can ice up solid and eventually the unit stops removing water entirely. What starts as 'it's still kinda working' can turn into a dead compressor in a few months. Not worth it.

How do I reset a GE dehumidifier E6 code?

There's no magic button combo. Unplug it, wait at least an hour in a dry room, plug it back in. That's your reset. If E6 clears after that, the sensor was just saturated and it's probably fine. If it comes back, the sensor's got an internal short or open circuit and needs to be replaced. Part number depends on your model but ADEL series sensors are usually around $15-25 from GE parts suppliers or appliance parts sites.

How much does it cost to fix an E6 error on a GE dehumidifier?

If it's just a saturated sensor that dries out on its own, it costs you nothing but an hour of waiting. A new humidity sensor runs $15-30 depending on the model. If you're paying a tech to come out and diagnose it, figure another $75-100 in labor on top of that. Honestly this is one of the easier DIY fixes on a dehumidifier. If you can use a screwdriver and follow directions, you can do this yourself in under 30 minutes.

Is E6 on a GE dehumidifier covered under warranty?

GE's standard dehumidifier warranty is 1 year parts and labor, and some models have a 5-year sealed system warranty on the compressor. A humidity sensor fault falls under the 1-year coverage. If your unit's still in that window, call GE before you start pulling anything apart. They'll either walk you through it or send a tech out. Keep your purchase receipt because they'll definitely ask for it.

Can I run my GE dehumidifier while it's showing E6?

Most GE dehumidifiers will shut down or refuse to run properly in E6 mode. If yours is somehow still running, I'd unplug it. Without humidity feedback the unit can't regulate its cycles at all, and running a dehumidifier blind like that is a good way to burn out the compressor way earlier than it should. Compressor replacement on a dehumidifier almost always costs more than just buying a new unit. So it's really not worth the gamble.
