Why Does My Levoit Humidifier Have a Red Light?

When the issue of a red light presents itself, you can see a red-colored droplet on the screen or a red glowing button, depending on your exact Levoit model.

Universally, this issue means that your Levoit humidifier has issues with water levels, filter, or hardware damage.

Here is a list of the most common causes of red light in Levoit humidifiers:

Now that you know what causes this issue to occur, let’s try some troubleshooting!

How To Fix Levoit Humidifier Red Light

Tip: Never pour hot or overly cold water into your water tank, as it might cause filter issues.

Step #1: Ensure Correct Water Levels

Levoit humidifier blinking red light is an indicator across most Levoit models that there is some type of issue with the water level.

Many smart humidifiers have built-in sensors that prevent the device from working unless certain water conditions are met. 

Here is how to ensure your Levoit humidifier has appropriate water levels:

1. Turn off your Levoit humidifier.
2. Remove the side or the top panel to access the water tank.
3. Open your water tank and refill the tank with clean water.
4. Pay attention not to overfill it above the indicated water level line.
5. Power on your device and reconnect the water tank.
6. Check if the red light turns off.

If you are unsure what the optimal water level is for your Levoit humidifier, check the owner manual.

Note: Always use distilled or demineralized water for your Levoit humidifier to extend device longevity.

Step #2: Check the Intake Port and Filter for Blockages

Suppose your Levoit water tank is properly filled, but the red light still persists.

In this case, it might be because water can’t properly reach the base of your Humidifier due to obstructions along the intake or mist dispersal vents.

The wick filter is also a common cause of this issue.

Here is how to ensure your Levoit humidifier device and filter are free of blockages:

1. Power off the humidifier unit and empty the water tank of any water.
2. Inspect the gasket and silicone seal around the base of your water tank.
3. If you notice obstructions, dilute 1 part vinegar into 1 part water and pour the mix inside your water tank.
4. Wait 30 minutes for the mixture to react with the mineral deposits and loosen them up.
5. Use any brush that is medium to soft in hardness and scrub off any blockages around the water tank seal.
6. Rinse with water and let it dry.

While waiting for the water tank to dry, it’s time to check your filter wick for congestion:

1. Locate the water wick filter, usually on the bottom of the tank or base.
2. Inspect the filter for any signs of mineralization deposits or plaque buildup. 
3. If depleted, order a replacement; trying to salvage it is not worthwhile.

Note: Regularly disinfecting your water tank ensures the mist remains safe for your health. 

Step #3: Blocked Nozzle or Air Path

Levoit humidifier flashing red light can also be caused if your mist nozzle or air path is obstructed.

This happens with regular use if the water quality isn’t good and small deposits of calcium or other materials start to develop around the nozzle or mist vent.

Here is how to ensure your Levoits nozzle or air path is unobstructed:

1. Disconnect the Levoit humidifier from the wall outlet.
2. Visually inspect the air path or intake vent for obstructions.
3. If the air path has dust or debris buildup, vacuum it and then brush away any particles.
4. Check your mist dispersal vent, usually at the top of the device, for signs of plaque.
5. If you notice buildup, dip a brush into vinegar and gently scrub off any plaque deposits.
6. Rinse with fresh water and let your nozzle dry down.

After these steps, power your Levoit humidifier and check if the red light is gone. If the calcification around the nozzle persists, repeat the above steps until clean.

Note: Never pour or dilute essential oils or medicine into the water tank itself.

Step #4: Check for Incorrect Settings

In some Levoit humidifier models, a red or amber warning light can also occur if your Levoit humidifier detects too high ambient room moisture levels.

Even if this is not the case, high ambient moisture can prevent your device from working at all.

Here are the steps to ensure your Levoit humidifier humidity settings are correct:

1. Locate your Levoit humidifier’s main control panel.
2. Look for a wheel or other buttons that control the mist intensity or humidity settings.
3. Turn the levels down so your overall room humidity is less than 50%.
4. Wait for a few minutes until your humidifier recalibrates and adjusts.
5. Monitor if the red light status goes away.

Note: If your home has an HVAC system, adjust its settings to reach the desired humidity levels.

Step #5: Ensure Poper Humidifier Placement

If your Levoit humidifier is incorrectly positioned or obstructed by furniture or other objects, it can cause it to malfunction and issue a red warning light.

To ensure this is not the cause, it’s best to check the humidifier setup.

Here are some general tips on proper humidifier placement:

• Ensure that the Levoit humidifier is at least 6-7 inches away from walls and objects.
• Avoid placing your humidifier in direct sunlight or near heat sources like other household appliances.
• Ensure your Levoit humidifier is set on a flat and level surface.
• Never put any objects on top of your humidifier, and ensure no obstructions to its air intake on the bottom side, such as thick carpets.

Note: Try moving your Levoit humidifier to a different room to see if the red light will disappear.

Step #6: Examine for Faulty Sensor

If your water level sensor is malfunctioning, it can cause false readings and issue a red light warning, even if your water level is correct.

To prevent this from occurring, you must find and clean the water level sensor.

Here is how to check your Levoit sensors for obstructions:

1. Check if your Levoit’s humidity sensor is clean and unobstructed.
2. Gently clean the sensor with a damp cloth until any buildup is removed.
3. Check inside your Levoit humidifier base for any water level sensors and clean them as well.
4. If you suspect your sensors are broken, it’s best to send the device for repair at a certified shop.

Note: Avoid using harsh detergents to clean your Levoit humidifier, as they might degrade its components.

Step #7: Check for Power Supply Issues

Issues with your Levoit power supply or with your home voltage consistency can cause your sensors and electronics to malfunction.

If there is damage to the power cable or the power strip, it can provide inconsistent electricity to your Levoit.

Here is how to check your Levoit power supply for issues:

1. Check the power cable is fully connected to the wall outlet.
2. Try plugging your humidifier into a different electrical outlet to see if the red light goes away.
3. If using a power strip, ensure it’s not overloaded by multiple working electronic devices.
4. Check the power adapter and humidifier base for signs of heat damage, like dark spots or a burnt odor. 

If you notice that your power cable is frayed and torn in some places, it’s best to replace the entire power unit. If you are unsure how to do so on your own, check with Levoit support for help.

Note: If you hear a buzzing sound within your Levoit humidifier, it might signal a blown fuse or capacitor.

Quick Recap:

To fix the Levoit humidifier red light, start by checking the water level inside your tank and examine the wick filter for blockages.

Next, check for a fault sensor and ensure proper humidifier placement.
