Is there an easy way to clean the detachable air filter on the dehumidifier, or is it supposed to be replaced periodically? I've tried to clean it by picking off the dust by hand but that takes forever. I'm afraid washing it with water will ruin it.
You can wash the filter with water, no problem. However, I would recommend replacing the filter every 3 to 4 months depending on how much you use the dehumidifier. The exposure to constant moisture will cause the filter to grow mold over time.

There are two major causes of a dehumidifier or air conditioner to freeze up the evaporator coil. First is lack of air flow try cleaning or replacing the air filter if it has one; make sure the fan is running and the coils are clean. Second is a low charge of refrigerant requiring a refrigerant leak check; repair and recharge. A slight overcharge will keep a dehumidifier from freezing in cooler ambient temperatures.
Typically the FILTER RESET light will illuminate after 250 hours of operation. To locate the filter, remove the bucket and the pull filter downwards. The filter can be clean by using clean water or vacuum cleaner extension hose. If you use clean water, please allow the filter to dry. Once you reinstalled the filter then replace the bucket. To extinguish the light simply press the FILTER button and your dehumidifier should resume normal operations. Remember it is best to clean your filter every two weeks based on normal operating conditions. Hope this helps! - Z
I understand your Frigidaire dehumidifier, model# FAD704TDP, is making a humming sound, when it is turned off. I also see that you have tried cleaning the filter and grill already, and want to know if there you should be concerned about this. You should not be alarmed by this. Providing, your dehumidifier is doing what it is supposed to do, and is taking moisture from the air, your appliance sounds like it is working fine. Hope this is helpful.
The most common cause of frost and ice buildup on a dehumidifier is
because the unit is operating in temperatures that are too cold. Many
dehumidifiers are not equipped to run at temperatures below 65 degrees
Fahrenheit. To fix this problem, Position the dehumidifier in an area where there is at least one foot of
clearance around the unit in order to allow for proper air circulation
during its operation. Close all windows, doors and other outside
openings to make sure your unit isn't attempting to remove moisture from
areas outside of the immediate room. Determine the temperature of the room by checking a nearby thermostat or
by using a hand-held thermometer.
Check the filter for dirt and buildup. Unplug the unit from the
electrical source and check the filter by opening the filter
compartment. If the filter is dirty, it will restrict airflow through
the unit and lead to freezing. Soleus recommends lightly vacuuming the
surface of the filter to remove dirt. The filter also can be washed in
warm water if it is extremely dirty. Once clean, place the filter back
in its compartment. Allow for the ice to melt and then restart your
Yes, it's easy to fix. Turn the Master ON/OFF Switch to OFF and unplug the unit. Remove the air intake filter and clean it. You can vacuum it or wash it. If you wash it, use warm water and dish washing liquid. Rinse and allow it to thoroughly dry before reinstalling it. DO NOT operate the dehumidifier without the filter installed.
A dehumidifier works just the way an air conditioner works
but in a reverse manner. If you encounter a problem with your
dehumidifier then it would be repaired the same way you would repair an
air conditioner. As such a dehumidifier does not require much cleaning
apart from changing the filter.
When the filter and coils of the dehumidifier are choked with dirt,
it may not pull out moisture from the air properly. The efficiency of
the dehumidifier gets decreased and the only solution is, to clean it
thoroughly. In order to assist you with the cleaning procedure of a
dehumidifier, following are a few tips:
Remove the water tank/container and clean it after
draining the water. Depending on the usage the container must be
Cleaning or changing the filter is also important for the main function
of ensuring a healthy atmosphere is performed by the filter. Mix some
bleach with warm soapy and clean the filter. It will help to get rid of
the bacteria, molds and mildew.
Use a vacuum cleaner to clean the evaporative coil/hot coil. Scrub off
the dirt using a brush but make sure that you don’t bend the fins while
Clean the condenser or the cold coil the same way. If the humidifier is
working in a room where the temperature is below 60 degrees Fahrenheit
then check the coils whether it is not icing up.
See to it whether the fins are bent or not, if they are bent then
straighten them out using a fin comb otherwise it might obstruct the
effective working of the dehumidifier.
And yes do not forget to clean the fan blades and other parts of the dehumidifier.
Keeping in mind the humidity level of your room, sets the humidistat of
the dehumidifier as keeping it too low or too high may only make the
dehumidifier to run longer than necessary.
Also before you start with the work of cleaning the dehumidifier, make sure that it has been unplugged.
How often does the unit run? Does the fan run when the unit is suppose to be running(as the fan pulls the air thru the filter). If every thing operates correctly and the filter is in the right location on the unit then all I can say is that you keep a clean house. Personally I only need to clean the air filter on my dehumidifier about once a summer. I wouldn't be overly concerned if it isn't getting very dirty.
We came home to this problem the other day, water all over the basement, leaking out the bottom left side, nothing in the collection basin but plenty would spill out if I tipped the unit forward. After searching the web and these forums I theorized that the coils were frozen. I let the unit thaw. No luck. I removed the faceplate and discovered thick, wet silt had filled the internal collection plate and was clogging the drain. I stuck a pipe-cleaner through the drain and the problem was fixed. Took some paper towels and cleaned the whole thing. Works like new. I assume the unit will need to be cleaned regularly to keep it going. To remove the faceplate, unscrew the two phillips' head screws under the faceplate along the sides, then take a flat head screwdriver and pop the tabs holding the face on, one tabe along each side. There are also two tabs on top, but you don't need to mess with those, as they simply act against gravity. Whole thing just clips back together after cleaning. I have no idea if this voids the warranty.
