Does the light clear after the bucket is empty and seated square?
The issue was bucket position or float movement. Clear film from the float area and rails so the bucket does not hang up again.

Midea Dehumidifier Bucket Full Light Stays On? Check Float and Hose
If a Midea dehumidifier bucket full light stays on, inspect bucket seating and float movement first, then try one no-hose bucket-mode run before pricing a switch.
A warning that clears with the hose removed points to hose routing. A warning that changes when you press the bucket points to bucket fit or switch contact.
One changed light tells you which path matters.
Don’t start with: Do not order a board, defeat the switch, or run it open. Stay with the bucket, float, hose, and switch contact.
Bucket mode firstEmpty the bucket, wipe around the float, and slide it in square before judging the switch.
Hose attachedRemove the hose for one trial. If the warning clears, fix the route; if pressing the bucket changes the light, inspect switch contact.
Do this first
- Unplug the dehumidifier before removing the bucket, wiping the float area, disconnecting the hose, or opening any access cover.
- Keep water away from the cord, plug, outlet, extension cord, power strip, display, and control area.
- Stop if the plug is hot, the cord is damaged, the outlet is wet, the unit smells burnt, or the breaker trips again.
- Do not defeat or jumper the bucket switch or float switch to make the dehumidifier run.
- Do not run the unit with cabinet panels removed.
- Clean only the bucket, float area, visible rails, and visible hose connection unless the service manual for your exact model says otherwise.
Two-minute bucket-full sorter
Does the float scrape, stick, or stay raised?
Clean mineral film and slime from the float path. Replace the bucket or float assembly only if it is cracked, warped, or still sticks after cleaning.
Is a drain hose attached?
Remove it for a bucket-mode trial. If the warning clears, rebuild the hose route downhill and clear the visible drain connection.
Does the light change when you lift or press the bucket?
That points to bucket alignment or switch contact. Look for worn rails, a warped bucket lip, or a switch that is barely being pressed.
Does the light never change with a clean seated bucket?
The bucket switch or water-level switch is now a reasonable part path, but match it by exact Midea model number.
Do you see water near wiring or heat damage?
Leave it unplugged and stop. That is service territory, not a bucket-cleaning job.
Bucket, float, and hose tell the story
Use what you can see from the front and hose connection before opening the cabinet. A warning that changes after the bucket sits square is a different problem than one that never changes.
Before you buy anything
Copy the full model number from the Midea rating tag before ordering a bucket, float, bucket switch, water-level switch, or drain hose. Buy a part only after the same clue repeats with a clean bucket, free float, and hose removed or routed correctly.
Start at the bucket and float
Most stuck full-light calls start at the part you already touch: the bucket. A Midea bucket can look installed while one rail, lip, or float is still holding the switch in the wrong position.
- Unplug the dehumidifier, pull the bucket out, and empty it fully. Even a small amount of sloshing water can hide a float that is stuck up.
- Set the bucket on a flat surface. Look for a warped front lip, cracked corner, mineral crust, or slime around the float hinge.
- Move the float gently through its travel. It should rise and drop without scraping, hanging halfway, or staying in the full position.
- Wipe the bucket rails and the front opening with a damp cloth, then dry the seating surfaces before reinstalling the bucket.
- Slide the bucket in square with two hands. The bucket should reach the same depth on both sides and should not spring forward.
Separate bucket mode from hose mode
A drain hose can keep the full signal alive when water backs up or the bucket is not seated the way the unit expects. Watch for whether the warning changes during one plain bucket-mode trial.
- Remove the drain hose and reinstall the empty bucket by itself.
- Run the unit briefly in normal bucket mode. Stay nearby so you can see whether the warning clears or returns right away.
- If bucket mode works, look for a high loop, kink, crushed spot, sludge, or a drain end pushed too tightly into the floor drain.
- If bucket mode still shows full, leave the hose out of the diagnosis and stay with the bucket, float, and switch-contact clues.
| What happens | What it usually means | Next move |
|---|---|---|
| Light clears with the hose removed | The drain route was backing up or confusing the bucket-full shutoff. | Rebuild the hose path downhill and clear the visible drain connection. |
| Light stays on in plain bucket mode | The hose is not the lead clue anymore. | Watch how the bucket contacts the switch after the float area is clean. |
| Light changes only while you press the bucket | Bucket fit, worn rails, or switch contact is marginal. | Inspect the bucket lip and rails before ordering a switch. |
| Light never changes with a clean seated bucket | A failed bucket switch, water-level switch, or wiring fault is more likely. | Match parts by exact model number or stop for appliance service. |
| Water appears near wiring, outlet, or the display | The repair is no longer a front-of-machine bucket check. | Leave the unit unplugged and schedule service. |
Clean the float without flooding the cabinet
Cleaning helps when the float is sticky, but keep the water on the removed bucket. Use a damp cloth on the float pocket, rails, and seating ledges, then dry them; if you see water tracks running toward the cabinet, display, cord, or outlet, leave the unit unplugged and stop.
- Use warm water, a small amount of mild dish soap, and a soft cloth on the removed bucket.
- Rinse the float area and dry it before reinstalling the bucket. A wet, slippery bucket can miss the rails as easily as a dirty one.
- Wipe only the visible rails and seating ledges inside the opening. Do not pour water into the cabinet.
- Do not use stiff wire, a drill bit, or harsh cleaner around the float, switch tab, or plastic drain opening.
- After cleaning, move the float by hand again. A healthy float drops cleanly without rubbing; if it still sticks, the bucket or float assembly is the part path.
What not to do first
A stuck bucket-full light by itself is not enough evidence for a control board. If the light changes when you lift or press the bucket, check the lip, rails, and switch contact first; forcing the bucket can break a part that was only misaligned.
- Do not order a control board from a bucket-full light alone.
- Do not shove the bucket in harder if it catches or sits crooked.
- Do not tape, hold, defeat, or jumper a bucket switch to keep the machine running.
- Do not run the dehumidifier while an access panel is off.
- Do not route a gravity hose uphill to a sink, standpipe, or window well unless your exact model has a pump designed for that lift.
- Do not keep testing if water is moving toward the cord, outlet, power strip, or display.
When a switch actually makes sense
A switch belongs in the cart only after the bucket and hose checks repeat the same clue. Watch how the light behaves when the bucket is seated, lifted, and removed.
- Look for bucket damage first. Choose a bucket or float assembly when the bucket is cracked, warped, missing the float, or the float keeps sticking after cleaning.
- Choose a bucket switch when the light changes only while you lift, press, or hold the bucket in one exact spot.
- Choose a water-level switch only if your model uses one separately and the clean bucket still reads full in normal bucket mode.
- Stop before control-board parts unless a technician has tested the circuit. Most homeowners cannot prove that fault from the front of the machine.
- Good clue before ordering: the same symptom repeats after the bucket is clean, square, and tested with the hose removed.

Why does my Midea dehumidifier say bucket full when the bucket is empty?
Usually the bucket is not seated square, the float is stuck up, or a drain hose is backing water toward the unit. If the light changes when you press the bucket or clears with the hose removed, follow that clue: clean the float, seat the bucket square, and retest before buying a switch.
Can a dirty bucket really keep the full light on?
Yes. Slime, mineral film, or lint around the float can keep it from dropping. It does not take much movement to hold the full signal.
Why does the light go off only when I push on the bucket?
That is a bucket-contact clue: the bucket is close enough to affect the switch but not pressing it cleanly. Pull the bucket, wipe the rails, check the lip for warping, and reinstall it square; if it only works while held in, switch contact is marginal.
Will a kinked drain hose cause the bucket full light?
It can. In continuous drain mode, a raised loop, sag, clog, or tight drain connection can back water up enough for the unit to act full.
Should I replace the bucket or the switch first?
Replace the bucket or float assembly only if it is cracked, warped, missing the float, or still sticks after cleaning. A switch makes more sense when a clean bucket changes the light only while you press or lift it.
Where is the bucket switch on a Midea dehumidifier?
It is usually near the bucket opening where the bucket, float, or a small tab can press it, but the exact location varies by model. With the bucket removed, use a flashlight to look for the contact point along the rails or back of the opening, and stop before wiring or sealed cabinet sections.
Can I run the dehumidifier with the bucket switch held in?
No. Do not defeat or jumper the bucket switch. That switch is there to stop overflow or unsafe operation when the bucket is missing, full, or misread.
What if the light stays on with the drain hose removed?
The hose is no longer the lead clue. Focus on bucket seating, float movement, switch contact, and model-matched switch diagnosis.
Do I need a Midea-specific replacement part?
Use the exact model number from the rating tag. Small switches and hose fittings can look close and still have different connectors, actuator shapes, or mounting points.
When should I stop and call for appliance service?
Stop if water reaches wiring or the outlet, the unit smells hot, the cord or plug is damaged, the breaker trips again, or diagnosis would require opening electrical sections.
