Question 1

the display says my humidity is 35% but my other hygrometer says 60%, which one is right?

Accepted Answer

DIAGNOSIS The sensor in the dehumidifier isn't always perfectly accurate, and its location matters. It's reading the air right at its intake, which might be drier if it's sitting in the path of an air vent or in a corner. FIX First, trust your standalone hygrometer if you know it's good. You can calibrate the Cube's behavior to match. Don't worry about the number on its display—use its "Target Humidity" setting. If your room hygrometer reads 60%, set the Cube's target to 50% or 45% and see if that gets the room down to your desired level. It's about the outcome, not the displayed number. Place your standalone hygrometer a few feet away from the Cube for a better room average. IF THAT DIDN'T WORK If the discrepancy is huge and persistent (like 30% difference), the internal sensor might be dirty or faulty. You can try gently vacuuming the intake grille on the back to clear any dust from the sensor, but there's no user-serviceable calibration for it. HEADS UP These built-in sensors are best for relative trends, not absolute precision. As long as the unit cycles on and off and maintains a comfortable room feel, the exact number on its display isn't critical. Use it as a guide, not a scientific instrument.

Question 2

the fan on this thing is way louder than i expected, it's like a constant whooshing roar, is it broken?

Accepted Answer

DIAGNOSIS The Midea Cube uses a turbo-style fan to move a lot of air, and on its highest speed (which is often the default when you first turn it on), it can be surprisingly loud. It's probably not broken, just running at max. FIX Try lowering the fan speed. Press the "Fan Speed" button on the control panel to cycle through the settings—it should go from High to Medium to Low. Low speed is significantly quieter and is often sufficient for maintaining a humidity level unless you're in a very damp, large space. Also, make sure it's not right up against a wall or curtains, as that can cause turbulent noise. IF THAT DIDN'T WORK If the noise is a grinding, rattling, or buzzing sound rather than a smooth whoosh, the fan might be hitting something or its bearings are faulty. Unplug the unit, remove the side panel and filter, and look inside with a flashlight. See if any debris (like a loose piece of foam or a bug) is near the fan wheel. If you see something, you can carefully remove it with long tweezers. HEADS UP Dehumidifier noise is very subjective. In a quiet bedroom, even Low speed might be noticeable. Placing it on a thick rubber mat or carpet pad can dampen some of the vibrational noise traveling through the floor.

Question 3

my cube is making a loud gurgling or bubbling noise, like water is running through pipes, is that normal?

Accepted Answer

DIAGNOSIS That gurgling is normal, especially when it first starts up or after it's been off for a while. It's the sound of refrigerant moving through the coils. It should fade after a few minutes of steady running. FIX Usually, no fix is needed—just let it run. However, if the noise is constant and very loud, it could mean the unit isn't level, causing the refrigerant to flow unevenly. Check that all four feet are firmly on the floor and the unit isn't rocking. Place a small level on top if you have one, and adjust the feet if possible. IF THAT DIDN'T WORK If the gurgling is accompanied by a hissing sound or gets worse, there's a small chance of a refrigerant leak. In that case, the dehumidifying performance will also drop noticeably. If it's under warranty, contact Midea. User-side repairs for refrigerant issues aren't practical. HEADS UP New units are often noisiest for the first 24-48 hours of operation as the system settles in. If it's just gurgling and otherwise working well, give it a couple of days before worrying.

Question 4

the continuous drain hose setup is leaking where it connects to the cube, water is dripping down the side.

Accepted Answer

DIAGNOSIS That leak is almost always because the drain hose isn't seated perfectly in the port, or the little rubber gasket/seal inside the port is missing or damaged. FIX First, turn off and unplug the unit. Pull out the water tank. Look at the drain port on the back—it's a round opening with internal threads. Unscrew the white plastic connector that came with the unit from your hose. Check that the small rubber O-ring or flat washer is still in place on that connector. Now, hand-tighten the connector firmly into the port on the dehumidifier. You shouldn't need tools; just make sure it's snug. Then attach your drain hose to the connector. The key is that the connector must be screwed all the way in, straight, not cross-threaded. IF THAT DIDN'T WORK If it still leaks, the internal plastic threading on the dehumidifier's port might be cracked. With the unit off, dry everything and wrap the threads of the plastic connector with a couple of layers of plumber's Teflon tape before screwing it back in. This can help seal minor imperfections. HEADS UP The drain hose must run downhill from the unit with no kinks or upward loops. Any back pressure from a sagging hose full of water can force it to leak at that connection point.

Question 5

how do you clean the filter on this cube dehumidifier? i can't figure out how to get the back panel off.

Accepted Answer

DIAGNOSIS You don't need to remove the whole back panel. The filter is designed to slide out from the side, but the fit can be snug and isn't super obvious at first glance. FIX Unplug the unit first. Look at the right side of the Cube (if you're facing the control panel). You'll see a small, recessed notch or a textured area along the vertical edge. Firmly grip there and pull that entire right-side panel straight outward. It's one piece that covers the filter compartment. Once it's off, you'll see the white foam filter. Just slide it out. You can rinse it under lukewarm water, let it air dry completely (this is crucial), and then slide it back in. Snap the side panel back into place until it clicks. IF THAT DIDN'T WORK If the side panel won't budge, double-check you're pulling from the correct side (the one without the control panel). Sometimes a thin plastic pry tool or a butter knife (used gently) in the seam can help get it started. Don't force it upward or downward—it pulls straight out. HEADS UP Never run the dehumidifier without the filter, and never put it back in damp. A wet filter can mold and will restrict airflow, which can lead to bigger problems like the unit freezing up or overheating.

Question 6

it's running but not pulling any water out of the air, the bucket is bone dry after a whole day.

Accepted Answer

DIAGNOSIS If the fan is running but there's no water collection, the compressor likely isn't kicking on. This could be a few things, but the most common culprit is the room temperature being too low for it to operate efficiently. FIX Check the room's ambient temperature. These units have a built-in protection that keeps the compressor off if the room is below about 65°F (18°C) to prevent icing up. Move the dehumidifier to a warmer room, or raise the room's temperature, and let it run for a few hours. Also, make sure the air filter on the back is clean—a clogged filter can restrict airflow and cause performance issues. IF THAT DIDN'T WORK If the room is plenty warm and the filter is clean, listen closely. Do you hear a faint hum or click every few minutes, like it's trying to start the compressor? If not, there might be a refrigerant or compressor issue. Ensure it's been sitting upright for at least 24 hours after moving it, so the refrigerant can settle. HEADS UP In a cool basement, it might run the fan but not actually dehumidify for hours if the air is cold. That's normal operation, not a defect. It's waiting for the air to warm up enough to start condensing moisture.

Question 7

just got this cube thing and the app won't connect no matter what i do, it keeps saying connection failed.

Accepted Answer

DIAGNOSIS This is a classic 2.4 GHz WiFi setup hurdle. The Midea Cube, like most smart appliances, only works on a 2.4 GHz network, and your phone might be trying to use 5 GHz or a mesh network that's causing confusion. FIX Here's the process that usually cracks it. 1) On your phone, go to WiFi settings and temporarily turn OFF any "Smart Switch" or "Auto-join" feature that jumps between 5G and 2.4G. Better yet, if you can, go into your router settings and give your 2.4 GHz network a different name than your 5 GHz one. 2) Connect your phone to that 2.4 GHz network. 3) Put the dehumidifier into pairing mode (hold the WiFi button on the unit for 3 seconds until the light blinks). 4) Now try the app setup again, making sure you're entering the 2.4 GHz network password correctly. IF THAT DIDN'T WORK Try a factory reset on the dehumidifier's WiFi. Unplug the unit, then hold down the WiFi button on the control panel. While holding it, plug the power back in and keep holding for another 5 seconds. The WiFi light should flash rapidly. Now try the setup process from scratch. HEADS UP If your router uses a "mesh" system like Google Nest or Eero, you might need to temporarily disable the 5 GHz band entirely in the router app during setup. It's a pain, but it works.

Question 8

my midea cube dehumidifier is flashing E1 and just beeping at me, what does that mean?

Accepted Answer

DIAGNOSIS That E1 code means the machine thinks its water tank is full, even if you just emptied it. It's almost always a sensor or float issue, not actual water. FIX First, power the unit off and unplug it. Pull the tank out and look inside for the little white float, usually on the side. Gently lift that float up and down a few times to make sure it's not stuck in the down position. While you're at it, check that the tank is sitting perfectly level on the base when you slide it back in. A slight tilt can mess with the sensor. Plug it back in and turn it on. IF THAT DIDN'T WORK If the E1 is still flashing, the tank sensor on the base might be dirty or obstructed. With the unit unplugged, get a cotton swab and some rubbing alcohol and gently clean the little plastic sensor posts where the tank sits. Let it dry completely before plugging it back in. HEADS UP This sensor is super sensitive. Make sure the tank is completely dry on the outside and there's no debris like a dust bunny blocking the float's path before you reinstall it.
