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.
There are a several things that can mimic a faulty humidity sensor.
1. The air intake filter is clogged and needs to be removed and cleaned.
2. The coiling coils need to be cleaned.
3. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures (Unless, you have a Low Temp Unit). This applies mainly to where the air
temperature at floor level is colder than at shoulder level in basement applications. Raising the unit up off the floor, onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a full tank of water, will usually resolve this problem.
If the above fails to help solve the problem, replacing the Humidity Sensor is certainly an option. But, before you jump into it, make sure you have an accurate wiring diagram, so you know which sensor is which. As the part does not come with installation instructions.

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.
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.
