Homedics Humidifier Red Light – How to Fix in 8 Easy Steps

There are multiple ways to fix the Homedics humidifier red light. We listed 10 easy solutions to help you troubleshoot the issue. 

1. Completely Discharge Your Homedics Humidifier

The first thing you should do is completely discharge your humidifier.

You must unplug it from the power source, empty the water tank, and let it sit for a few minutes.

Doing this resets the humidifier and clears any errors causing the issue. 

Here are the steps to do it:

1. Unplug your Homedics humidifier from the power source.
2. Remove the water tank or reservoir from the base and empty it. 
3. Let your humidifier sit for a few minutes without any power or water.   
4. Reattach the water tank to the base and ensure it seats properly. 
5. Refill it with clean water up to the fill line. 
6. Plug your humidifier back into the power source. 
7. Turn it on and see if the red light is gone. 

Note: Different models have varying guidelines on discharging. Refer to your humidifier’s user manual for specific instructions. 

2. Reseat the Water Reservoir Properly

The humidifier sensor won’t accurately detect the water level if the tank isn’t seated correctly on the base.

To fix this, reseat the reservoir properly. After ensuring it’s in the correct position, check if the red light has turned off. 

Here’s how to do this:

1. Turn off your humidifier and unplug it from the power source. 
2. Remove the tank or reservoir from the base. 
3. Check for signs of damage.
4. Replace the tank if you see cracks.
5. If you don’t see any damage, align the tank and ensure it clicks into place. 
6. Plug your device back into the power source and turn it on.  

Note: Ensure the water tank or reservoir is clean and free from mineral or mold buildups. Regularly clean it to ensure a smooth operation.

3. Check the Water Level and Fill the Reservoir

Another possible reason you’re seeing a red light on your Homedics humidifier is the water level in the tank.

Your device won’t function safely and properly if the water level is too low or too high. To fix this, check the water level and fill the tank accordingly.

Follow these steps to do this:

1. Turn off and unplug your humidifier.
2. Remove the water tank or reservoir from the base.  
3. Check the water level, comparing it with the fill line marked on the tank. 
4. If it’s too low, add more water to the fill line. 
5. If it’s too high, pour the water until it reaches the fill line.
6. Reattach the water tank to the base.
7. Plug in and turn on your device. 

Note: Overfilling often leads to spillage or improper operation, while underfilling causes the humidifier to shut off prematurely. 

4. Replace the Filter of Your Humidifier

The filter removes impurities from the water and prevents mineral deposits from forming on the nozzle.

If it’s dirty or damaged, you’ll experience Homedics humidifier not working red light. To solve this, replace the filter with a new one. 

Here are the steps to do this:

1. Turn off and unplug your humidifier.
2. Remove the water tank or reservoir from the base.  
3. Locate the filter compartment and open it.
4. Pull out the old filter and dispose of it properly. 
5. Insert a new filter and close it.
6. Reattach the water tank to the base.
7. Plug in and turn on your device. 

Tip: After replacing the filter, monitor the humidity levels in your room and adjust the humidifier settings as necessary. 

5. Clean the Fan to Remove Dust and Dirt

Check the fan to see if your Homedics humidifier’s red light stays on.

The fan blows air through the mist nozzle to create a cool or warm mist.

Over time, dust and dirt accumulate on its blades, reducing airflow and causing the red light to come on. 

To fix the issue, clean the fan by following these steps:

1. Turn off and unplug your humidifier.
2. Remove the water tank or reservoir from the base. 
3. Locate the fan cover and unscrew it. 
4. Gently clean the fan blades with a soft brush or vacuum cleaner. 
5. Screw back the fan cover. 
6. Reattach the water tank to the base.
7. Plug in and turn on your device. 

Tip: Establish a regular cleaning schedule to prevent dust and dirt buildup. Use a solution of one part vinegar and two parts water to prevent bacteria, mold, or mineral buildup.  

6. Make Sure the Float Switch is Working

If you find that the float switch is stuck or broken, it could be why your Homedics humidifier red light is on.

To resolve the issue, ensure the float switch is working properly.

Here are the steps to do this:

1. Turn off and unplug your humidifier.
2. Remove the water tank or reservoir from the base. 
3. Locate the float switch and check if it’s moving freely or not. 
4. If it’s stuck, gently tap or shake it to loosen it up. 
5. If it’s broken, replace it with a new one.
6. Reattach the water tank to the base.
7. Plug in and turn on your device. 

Tip: Ensure the float switch and the surrounding area are free from dust, dirt, or mineral buildups as they impede movement. 

7. Set the Humidistat Correctly

The humidistat allows you to adjust the humidity level in your room.

If set too low or too high, your humidifier will stop working and display a red light.

Set the humidistat correctly according to your preference and current weather conditions to fix this.

Here are the steps to do this:

1. Turn off and unplug your humidifier.
2. Locate the humidistat dial and check its current setting.
3. Turn it clockwise or counterclockwise to increase or decrease the humidity level.
4. Use a hygrometer to check the current humidity level in the room.
5. Plug in and turn on your device. 

Note: Adjust the humidistat until you reach your desired humidity level or until the red light is gone. The recommended humidity level for most people is between 40% and 60%.  

8. Use Distilled Water to Avoid Scaling and Mineral Deposits

Tap water often contains minerals that cause scaling and deposits on your device’s parts, especially the filter and mist nozzle.

On the other hand, distilled water is purified and free of minerals.

Distilled water is recommended to keep your humidifier running smoothly and prevent the red light from coming on.

Here are the steps to use distilled water:

1. Purchase distilled water from a grocery store or make your own. 
2. Turn off and unplug your humidifier.
3. Fill the water tank or reservoir of your Homedics humidifier with distilled water.
4. Ensure you fill it up to the fill line. 
5. Plug in and turn on your device. 

Tip: To make distilled water, boil tap water and collect the steam in a clean container. 

If you’ve tried all the above solutions but continue encountering a red light on your humidifier, check the user manual for troubleshooting tips and error code explanations.
