Frequently Asked Questions
Hisense dehumidifier E2 — can I still use it to collect water?
With E2 active the unit cannot properly regulate humidity. It may still run but without reliable sensor data it will not dehumidify effectively. Have the sensor repaired before continued use.
Hisense dehumidifier E2 and E4 at the same time — what does that mean?
Multiple errors appearing together usually indicate moisture damage to the control board rather than individual sensor failures. The entire control board may need replacing — contact Hisense service.
Hisense dehumidifier purchased on Amazon showing E2 — is it covered under warranty?
Yes, Hisense offers a 1-year limited warranty on their dehumidifiers. Contact Hisense support with your purchase order number. Units purchased through Amazon may qualify for Amazon return as well.
