How to Fix Vicks Warm Mist Humidifier Red Light?
Tip: Follow our guide in order without skipping over steps for the best result!
1. Refill the Water Tank
To fix a red light on Vicks warm mist humidifier, you can attempt to refill the water tank to the appropriate level.
Most models of Vicks humidifiers have the red light as an indicator for insufficient water levels.
Here are the right steps to ensure your Vicks humidifier has the correct water amount:
- Turn off and unplug the Vicks warm mist device.
- Carefully remove the water tank from the Vicks humidifier base.
- Refill the tank with clean, cool water.
- Place your Vicks water tank back onto the base and ensure it’s fully clicked into place.
- Plug in and turn on the Vicks humidifier.
- Check if the red light has turned off.
If you are uncertain where to fill your water tank, look for a horizontal line indicator or check your device user manual for more details.
Note: You should use demineralized or distilled water when possible to prevent plaque buildup.
2. Reset the Vicks Humidifier
Since Vicks humidifiers rely on sensors to tell them if something has gone wrong, these sensors could sometimes malfunction.
The most common cause for this is software errors; the best way to get rid of them is to reset your humidifier.
Here are the proper ways to reset your Vicks humidifier:
- Turn off the humidifier.
- Unplug it from the electrical outlet, and if your power adapter is removable, take it off.
- Wait about 5 minutes so your device has ample time to discharge any residual electricity.
- Plug the humidifier back in and turn it on.
- Wait for a few minutes for your sensors to get a proper reading again.
- Lastly, check if the red light is off.
Note: If your room's ambient temperature is too low or too high, this can cause issues.
3. Clean the Water Tank
Vicks humidifier’s red light with water can be due to plaque buildup on the water tank, causing your water level sensors to get a false reading.
It’s imperative that your water tank is regularly cleaned and disinfected to minimize health risks.
Here are the right ways to clean your Vicks warm mist humidifier water tank:
- Turn off and unplug the Vicks device.
- Carefully remove its water tank from the base.
- Pour out any remaining water.
- Clean the inside of the tank with a mix of white vinegar and water.
- For optimal results, mix 1 part vinegar with 1 part water.
- Rinse thoroughly with clean water.
- Reassemble and test the Vicks warm mist humidifier for the red light issue.
If your red light is still flashing after thoroughly cleaning the water tank, check if the water intake port is obstructed by plaque.
Clean it with the same vinegar and water solution to ensure your water can reach the humidifier mister without obstructions.
Note: If you notice a stale smell from the water tank, mix isopropyl alcohol with water to clean it.
4. Clean the Heating Element
Vicks mist humidifiers have an internal heating element that makes the mist warm as it gets aerosolized.
An issue with your heating element could cause your device to overheat and give a false red light for low water levels.
Here are the steps to clean your Vicks humidifier heating element:
- Ensure the unit is turned off and unplugged.
- Empty the base of any water.
- Pour white vinegar into the base, enough to cover the heating element.
- Allow it to sit for 20-30 minutes.
- Use a cleaning brush to scrub any mineral deposits gently.
- Rinse thoroughly and reassemble the unit.
Note: If you don't know how to reach your Vicks heating element, reference its instruction manual.
5. Check for Proper Seating of the Tank
Sometimes, your Vicks warm mist humidifier will issue a red warning light because the water tank is not correctly placed.
This can cause your device to think that the water level is low. To prevent this issue, you must verify the placement of your water tank.
Here is how to check your Vicks water tank for correct placement:
- Power off your device completely.
- Remove the water tank from the Vicks humidifier base.
- Ensure no objects or debris are preventing the tank from sitting correctly.
