10 Proven Fixes to Fix Homedics Humidifier Keeps Turning Off 

There are multiple ways to address the issue. Tackle the following solutions one by one until you find one that works. 

#1: Move Your Humidifier Away From Walls to Prevent Overheating

The first thing you should do is move your Homedics humidifier away from any walls or other objects that block the airflow.

Humidifiers need enough space for the air to circulate to prevent them from overheating. 

1. Unplug your Homedics humidifier and let it cool down. 
2. Remove the water tank from the base and empty it. 
3. Lift the base and move it to a new location. 
4. Place it on a flat and stable surface.
5. Refill the water tank with clean water and place it back on its base.
6. Plug in your humidifier and turn it on.

Note: Per the instruction manual, place your humidifier at least 3 feet away from any walls. 

#2: Confirm Your Humidifier’s Power Situation

Next, confirm if there’s a blown fuse, faulty outlet, loose connection, power outage, or tripped circuit breaker.

One of these is a potential reason your humidifier is not receiving the power it needs to function properly. 

Below is a table illustrating what to examine and how to address each issue:

Check For	Solution
Power outage	Wait until the power is restored.
Loose connection	Plug the power cord firmly and ensure it’s not damaged or frayed.
Faulty Outlet	Use another power outlet nearby.
Tripped circuit breaker	Reset the circuit breaker
Blown fuse	Replace the fuse

Tip: Regularly inspect your humidifier’s power cord and connections to address the issue proactively.   

#3: Make Sure Your Water Tank is Full and Properly Seated

“My Homedics humidifier keeps turning off. What should I do?” If your device keeps turning off, check the water level in the tank and ensure it is properly seated on the base.

An empty tank means no water flows into the base to activate the mist or steam function. 

1. Remove the water tank and check the water level. 
2. Refill it with clean water up to the maximum fill line if it is low or empty. 
3. Check the bottom of the tank for cracks or leaks.
4. If you find signs of damage, replace it with a new one. 
5. Check the rubber seal or gasket for dirt or debris. 
6. Clean it with a damp cloth or replace it with a new one. 
7. Place the water tank back onto the base. 
8. Ensure it is properly seated and aligned. 

Note: Refrain from overfilling or underfilling your water tank. Also, you’ll know it’s properly seated when you hear a click. 

#4: Check the Filter for Clogs and Mineral Build Up

A dirty or clogged filter restricts airflow and water flow, reducing your Homedics humidifier’s performance.

To fix this, check for mineral deposits and clean or replace the filter depending on its type.

Here are the steps to do this:

1. Remove the water tank and set it aside. 
2. Locate the filter compartment.
3. Slide or lift the cover to open it.  
4. Remove the filter and inspect for clogs, mineral buildup, discoloration, and damage.
5. If you find any, clean them with a soft brush or cloth.
6. Rinse it with cool water. 
7. Let the filter air-dry completely before putting it back. 
8. Slide or snap the cover back into place. 

Note: Clean the filter every two weeks or more often, depending on your water quality and usage. Then, replace it every 6 months or sooner if worn out or damaged. 

#5: Make Sure Your Humidifier is on a Level Surface

If your humidifier is uneven or tilted at an angle, it will cause the water level sensor to malfunction.

As a result, the unit will turn off prematurely. So, ensure you place it on a level and stable surface. 

1. Remove the water tank from the base and empty it.
2. Carefully lift the base and place it on a flat, stable surface. 
3. Use a level tool to check if the surface is even and horizontal.
4. Adjust it if necessary. 
5. Refill the tank with clean water and place it back onto the base. 

Tip: If the surface is uneven, use shims or furniture levelers to balance your Homedics humidifier and keep it stable. 

#6: Give Your Humidifier a Break to Cool Down

Your Homedics humidifier will overheat if you use it continuously for hours or days without turning it off.

To avoid this, give your device a break every few hours to cool down. Then, adjust the settings to lower the mist output or turn on the automatic shut-off feature. 

1. Press the power button to turn off your humidifier. 
2. Unplug it from the power source.
3. Let it cool down for at least 30 minutes.
4. Check and clean other other components of your humidifier. 
5. Plug in your device after 30 minutes and turn it on.
6. Adjust the settings based on your preference and room conditions. 

Note: Avoid running your humidifier continuously for over 12 hours to keep it from overheating. Turn it off when you’re not using it or leaving the room. 

#7: Remove Scale Buildup from Your Humidifier’s Components

Scale is a crusty substance that forms when minerals in the water evaporate and deposit on your humidifier’s parts.

It reduces the efficiency and lifespan of your device, causing it to turn off. To address the issue, remove the scale buildup.  

To do this, follow these steps:

1. Unplug your humidifier and let it cool down. 
2. Remove the water tank from the base and empty it. 
3. Remove the nozzle or mist outlet and set it aside. 
4. Fill a large bowl or sink with vinegar and water in a 1:1 ratio. 
5. Soak the nozzle or mist outlet in the solution for at least 15 minutes.
6. Use a soft brush or cloth to scrub away the scale. 
7. Rinse the nozzle or mist outlet with clean water.
8. Let it air dry completely. 
9. Repeat steps 4 to 8 for other parts of the humidifier.
10. Reassemble your device and turn it on.

Tip: Add lemon juice or baking soda to the vinegar solution to enhance the cleaning effect. 

Note: Remove the scale buildup from your humidifier’s components every month or more often, depending on your usage and water quality. 

#8: Use Distilled Water

If your Homedics humidifier turns off constantly, use distilled water instead of tap water.

Distilled water doesn’t damage your humidifier or cause scale buildup because it is purified, meaning no minerals and chemicals.

Rather, it helps improve the quality and output of your device’s mist or steam. 

1. Unplug your humidifier and let it cool down. 
2. Remove the water tank from the base and empty it. 
3. Fill the tank with distilled water up to the maximum fill line. 
4. Place the tank back on the base. 
5. Plug in your device and turn it on.

Pro Tip: If you can’t buy distilled water from grocery stores, make your own by boiling tap water and collecting the steam in a clean container.  

#9: Inspect the Float Valve

Next, check the float valve. The float valve regulates the water level and flows into the heating element. It needs to be in the correct position for the Homedics humidifier to work properly.

If it’s stuck or malfunctioning, the heating element will overheat and short-circuit, causing the issue. 

1. Locate the float valve (small plastic ball with metal rod). 
2. Gently lift and lower it several times to check if it moves freely and smoothly. 
3. Use a soft brush or cloth to clean any dirt, debris, or scale around it.
4. Check if the float valve is damaged or broken.
5. If so, replace it with a new one. 

Note: Go to the Homedics website or other online retailers to purchase a new float valve. Also, contact customer support for assistance. 

#10: Adjust the Humidistat Setting

If none of the above solutions work, adjust the humidistat setting. The humidistat plays a crucial role in controlling humidity levels.

If set too low, the humidifier will turn off when the room is humid enough. If it’s set too high, it will turn off when dry. 

1. Unplug your humidifier and let it cool down. 
2. Locate the humidistat knob or button with a drop or percentage symbol. 
3. Turn the knob or press the button to adjust the humidistat setting. 
4. Use a hygrometer to measure the humidity level in the room. 
5. Plug in your humidifier and turn it on.

Note: The recommended humidity range is 40-60%. Adjust the humidistat regularly to maintain a comfortable and healthy humidity level in the room. 

Quick Recap

The main reason your Homedics humidifier keeps turning off is power issues. To fix this, inspect the power source by ensuring the cord is securely connected and the outlet works properly.

If the problem persists, consult the manual or contact customer support.
