Homedics humidifier not working: Common issues
If your Homedics humidifier is not working correctly, you will experience dry air in the house.
The most common problems of your Homedics humidifier not working are as follows:
- It fails to work out of the box while it is still new
- Works for a bit and then it stops
- It runs and refuses to make mist
- Homedics humidifier shows red light
- The humidifier stops working after cleaning it
Homedics humidifier not working red light: 2 causes
The light on your Homedics humidifier unit should be green, if it is working correctly. If it shows red and is not working, try the following things:
There is no water in the tank
Check the tank. If it is empty, the light will illuminate in red. If you refill it with water to the right level, the light will turn green.
The humidifier is dirty
There is a second light on the Homedics humidifier. This light shows you the cleanliness status of the unit. If it is dirty, the light will illuminate red. The unit will continue running, but it could be pumping mist contaminated with mold and bacteria.
If this is the case, you will need to follow the full process of cleaning a humidifier. Use the recommended products to kill bacteria and mold.
If you have been using demineralization cartridges to remove minerals from the water in the tank, please remember to clean them too, or replace them altogether.
Homedics humidifier stops working after cleaning
When you clean a mister, you will have to take it apart, remove the tank, the base, the plastic covers and so on.
This means you might disrupt something, or reassemble it incorrectly. This might cause the unit to fail working as expected.
Check the following things if the unit stops working after cleaning:
Water has leaked into the circuitry
If the humidifier tank is full of water, some of the water could have gotten into the circuitry.
This is easy to fix, but it will take some time. You should try the following things:
- Pour the water out of the tank
- Place the humidifier upside-down to drain all water out of the base
- Leave it that way for several hours
- Disassemble the unit – use a screwdriver
- Wipe the circuitry with a paper towels, dabbing it so the paper towels absorb the water
- Air-dry it for several hours or overnight and then put it back together
Float valve is not working correctly
Check whether the float valve is floating just fine. If it is not, your humidifier will not work.
If the valve is not floating, try pushing it with your hand or something and once it floats, the humidifier will work.
Perhaps you forgot the plastic packaging on the pump
If the humidifier is new, find out whether you removed the Styrofoam or plastic packaging around the pump. If you don’t remove it, the unit is not going to work correctly.
To correct this, just drain the tank and remove the Styrofoam packaging on the pump. Fill the tank with water and run it again.
Homedics cool mist ultrasonic humidifier troubleshooting
Humidifiers face many issues. If you have one at home, you should learn how to troubleshoot it. To help you, HoMedics has put together a comprehensive support book for all of their products. You can download it.
Luckily, the operation of a humidifier is not rocket science. If we are dealing with the first instance of humidifier just not working right out of the box, do the following:
i) Read the Homedics humidifier user manual
The Homedics brand name has many air purifiers, dehumidifiers, diffusers and humidifiers in its stable.
When the unit is delivered, check that it has a user manual. If it does not come with a hard copy one, you can get it from their website or other online sources.
You will also find cautions and warnings that you should not overlook. There are clear instructions for setting the unit up, for cleaning and for storage.
This user manual also comes with troubleshooting tips. For instance, if the humidifier is running, is not increasing humidity and is not making mist, you should check whether the tank is attached properly.
Sometimes, you might notice that the unit is not producing mist. Check the water level, and pour the excess out.
They even have tips for transporting the humidifier, making sure it does not spill water in transit.
What we are trying to emphasize here is the need to read the humidifier user manual. Some things such as opening it up and trying to fix things can nullify the warranty.
When you read the user manual, you can retrace your steps to find out whether you missed a step. If everything seems right with the setup, continue reading to the next step.
ii) Is it plugged in correctly?
Find out whether the humidifier fully plugged into the socket. This is a common occurrence by the way. If not fully pushed in, the plug will not work.
You can also check whether a switch in the circuit breaker has tripped. If yes, just raise it back up and find out whether the humidifier works okay.
Sometimes, when you run appliances, some switches may flip off automatically. So check that out.
iii) Does it sit on a flat surface
Modern humidifiers have many safety features. One of them is that anti-tip function which ensures that the humidifier stays upright all the time.
However, a humidifier with this feature might not work if it is not flat on the table.
If you have done everything and the humidifier still will not turn on, check whether it sits level on the table or floor. Also remember, it is better to place it high rather than on the floor for maximum efficiency.
Another thing that you might want to check is whether the humidifier has child protection functions.
If such a function is turned on, it might refuse to turn on until you switch the function off.
iv) There is white dust after running the unit
If you use hard water or even tap water in your ultrasonic cool mist unit, the humidifier will leave white dust on surfaces.
If this happens, just clean the unit and then use distilled water only. You can also use a demineralization cartridge in the unit. This is going to prevent the formation of white dust.
While other humidifier types don’t cause white dust, it’s better to use the recommended water type since they can still disperse mineral traces in the mist.
Besides, the humidifier filter will be doing too much work and will need replacement sooner.
v) The base leaks water
Many things can cause water to spill in the area immediately surrounding the humidifier. However, the most common ones are:
- Placing the unit on a slanted surface – unplug it and place it on a level surface
- The humidity level is set very high – set it lower
- The mist is falling on a surface, condensing and rolling down – Just keep the unit a good distance from walls and furniture
vi) The mist has a foul odor
If the mist has a bad smell, it means the unit is dirty. Bacteria, minerals and mold in the humidifier cause foul odors.
Do not add anything apart from water into the unit. If you put essential oils in the tank, it could also alter the smell of the mist.
Vii) It is producing too little mist
If the water in the humidifier is too cold, the Homedics ultrasonic cool mist might produce a low amount of mist. It is a cool mist, rather than a cold water humidifier.
If the ultrasonic disc is dirty, the humidifier will also produce low mist. It can also fail to produce any altogether.
Homedics Humidifier Does Not Produce Mist
Sometimes, the humidifier will turn on okay. But it might not produce mist. When people complain of ultrasonic humidifiers not working, mostly, this is what they mean.
Here is how to fix the problem of Homedics humidifier no mist:
The humidistat is not adjusted properly
Have you cleaned the humidifier and then it failed to produce mist but it seems to be running okay?
The culprit could be the humidistat. It has not yet adjusted to the humidity in the room, so it is not sending the dry air signal to the control board.
After cleaning the unit thoroughly, give it enough time for the humidistat to adjust to the humidity in the room. A few hours should be fine.
The tank doesn’t have enough water
When a humidifier is not working, always start with the basic checks. For instance, start by checking whether the appliance has water.
If it has a little amount of water, top it up and check whether it will start producing mist.
The humidifier is not on level surface
If a humidifier is not on a level surface, some models might refuse to create mist. This safety feature protects the appliance from tipping over.
Therefore, once again, check whether it is level on a flat position. Check whether the humidifier is connected to electricity.
The tank is not fitted properly
If the humidifier tank is not installed properly, the humidifier might not produce mist.
Remember, you have to detach the tank from the humidifier to fill it with water and then reattach it.
If the tank sits sideways even by a small margin, it is not going to produce mist. You might feel air coming out, but it will not be misty.
The power is not enough
If there is not enough power in the socket, the unit will not make mist. It might even fail to run. Check the amp rating of the appliance given by the manufacturer and plug it into the appropriate socket. .
You can test the socket where you have plugged in the appliance with another appliance. If it works, the humidifier could be the problem.
The unit is too old
Sometimes, an old humidifier might just start failing of its own volition. If it has lasted several years, it might be time to buy a new one.
You can take the humidifier to a repair shop. Most likely, if it is too old, it will not be under warranty.
If it is not too old, you can check whether it is under warranty. Call the seller to direct you to their approved repair shop.
Portable humidifiers last 3 to 5 years. If you are fortunate, yours will last 7 years. If you have been using it that long, it is time to let go.
The spout could be clogged
When a humidifier turns water into mist by boiling it or using ultrasonic vibrations, the mist gets out through a small spray outlet.
If you use tap water in the humidifier, it will have high mineral content. A mineral layer could block the outlet and no mist will get out.
The same thing would happen if the unit is dirty. If you have hard water in your taps, clean your humidifier as often as possible.
You can read our article here on how to clean a humidifier. There will be no debris blocking the spray hole.
If you do not clean a humidifier, it will pass whatever contaminants might be in the humidifier tank to the mist. If it has mist, you will start to experience signs of mold toxicity.
The ultrasonic disc is dirty
The ultrasonic disc can get dirty from time to time. That’s why your humidifier should come with the right brush for cleaning it.
If the disk is dirty, your Homedics humidifier will not produce mist. The disc is located in the center of the base. To clean it, you will need to detach the tank.
Clean it lightly with the provided brush and be careful not to scrape it. Usually, this gets the humidifier working again.
The humidifier ultrasonic disc wears out with time. You would need to replace it with a new one.
