Midea Dehumidifier Error EH — How to Fix It

What it means

Midea dehumidifier error EH indicates a humidity sensor (hygrometer) fault.
The sensor has failed or is reading outside its valid range.
Unplug the unit for 30 minutes to reset — if EH persists, the sensor needs replacing.

How to Fix It

Unplug and reset for 30 minutes

Disconnect the unit from the wall socket and leave it unplugged for 30 minutes.
Reconnect and power on.
A temporary humidity sensor read error often clears after a full power reset.
Move the unit to a normal humidity environment

The humidity sensor may show EH if the relative humidity is extremely high (over 95%) or extremely low (under 20%).
Run the unit in a room with more moderate humidity to see if the error clears.
Clean the air filter

A dirty filter restricts airflow and affects sensor readings.
Remove the filter panel, wash the filter under cold water, allow it to dry completely, and refit.
Test the unit again.
Check for moisture on the sensor or PCB

If the unit was stored in a very humid environment, moisture on the sensor or main PCB can cause false EH readings.
Unplug the unit and allow it to dry in a warm room for 24 hours before restarting.
Contact Midea service for sensor replacement

If EH persists after a reset and drying period, the internal humidity sensor has failed.
Midea customer service can advise on repair options or supply a replacement sensor for authorised service agents.

Frequently Asked Questions

Midea dehumidifier EH error but room feels very humid — is the sensor wrong?

Yes, EH means the sensor is reading incorrectly.
The actual room humidity may be fine.
With a faulty sensor, the dehumidifier cannot regulate humidity properly and should not be relied upon until the sensor is repaired.

Can I run a Midea dehumidifier in continuous drain mode to bypass EH?

Some Midea models allow continuous operation in drain mode at a fixed fan speed, bypassing the humidity sensor logic.
Check your model manual for a continuous or manual mode option.
This is not a permanent fix.

Is the EH error the same as the humidity sensor error on other dehumidifier brands?

Yes.
EC and EH error codes are shared across many Midea-manufactured dehumidifiers including models sold under the Comfee, Toshiba, and Frigidaire brands.
