HoMedics UHE-WMTF185 Warm Mist Is Not Warm Yet
Warm mist is not immediate on this model. HoMedics says it takes approximately 20 minutes to heat after warm mist is selected.
HoMedics UHE-WMTF185 Clean Icon Will Not Turn Off
Clean the ultrasonic membrane first, then press and hold the clean transducer reset button until the red indicator turns off.
HoMedics UHE-WMTF185 Cycles Off at the Humidity Setting
This can be normal. The programmable humidistat cycles the unit off at the set humidity and back on after room humidity drops 7% below the target.
HoMedics UHE-WMTF185 Red Out-of-Water Indicator Is On
The red out-of-water indicator means the tank is empty enough for the humidifier to shut itself off. Refill the tank; a small amount of water in the reservoir afterward is normal.
HoMedics UHE-WMTF185 Is Leaving White Dust
White dust comes from minerals in hard water, not a defect. Use distilled water and replace the demineralization cartridge when buildup increases.
HoMedics UHE-WMTF185 Is Making Excessive Noise
The troubleshooting table points first to an uneven surface or low water level.
