I had the delonghi dehumidifier and ran into similar difficulty. It frose the humidity instead of draining it and turned the evaporator coil into a block of ice. Their service desk may tell you otherwise, but my difficulty was in the unit controls. All manufacturers must play by the same thermodynamic rules and I don't think they understand them. Their guarentee required me to shlep it to a service center an hour and a half away. I took it back to the store and got my money back. I was attracted by their built-in condensate pump, but that couldn't overcome lack of performance.

I bought a soleus 40 pint unit, put it on a shelf screwed to the wall and gravity drained the condensate with a hose. It's quiet and I haven't looked back.

Esco Oasis 2700L dehumidifier ices up. Is there a filter to be cleaned and if so, how to I get to it?


Hi,

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 dehumidifier.

Does not collect water in bucket but runs all the time


Does it have a filter?

"
It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises."

Need a repair shop in the baltimore area to look at my dehumidifier runs but wont pull water


It's cold outside. If the temperature is too low, the cold coils will just frost up and you won't get much water 'pulled'.
Check to see if the cold coils actually are getting cold when the unit is running and the control is set to cause the compressor to work-not just the fan.
If the coils are cold and full of frost or ice, the room is too cold for the dehumidifier to work. You'll have to raise the temperature of the room or wait for warmer weather.
If the coils never get cold, the compressor might be bad or the unit might have lost its freon.
I wonder, though, if it's just too cool and dry right now for a dehumidifier to be pulling more moisture out of the air.
Hope this helps!

The filter (on some models) may be dirty or clogged. If so, clean the filter. For instructions on cleaning the filter.

I hope this help to solve, if this answer solve it, remember to rate it. Good luck.

HOW TO USE


Hello,

follow the instructions below on how to use your dehumidifier:

Prepare the room for the dehumidifier by vacuuming, dusting and cleaning the room. Be especially careful to have all mold removed prior to using the dehumidifier.
Plug in the dehumidifier into a grounded outlet.
Set the dehumidifier to high in order to remove excess moisture from the room.
Wait for the dehumidifier to run several cycles, removing all undesired moisture from the air. This may take days or even weeks in especially damp rooms.
Adjust the setting of the dehumidifier when the air has reached your desired comfort level. Make the setting one that will maintain the current conditions.
Good luck.

My dehu has frost on coils most of the the


if the room air is cooler than the dehumidifier then they will frost over. normally frosting over means loss of freon but because it is a closed system there probably isn't. if the air's moisture level [humidity] is low then don't even run the machine.

Haier Dehumidifier stuck on 45


Check the coils at the back of the dehumidifier to see if there is any frost buildup on it. If there is, turn off the machine for a while until the room warms up and melts off the frost. The machine works by condensing the moisture in the air over these coils, so if the coils are frosted over, or are not cold enough, the moisture cannot condense. If the coils are not cold enough, you may want to get it refilled with refrigerant. You will need to take it in for servicing in this case.

Hope that helps! Should you have any further questions, please feel free to post them here.

P.S. - If you find that the solution/answer I provided led you to, or resulted in a fix, please close the ticket with a FixYa! rating. I would be very grateful for your show of appreciation.

Frosted Coils


You prob do have a restriction in the sealed system. This causes the coils to not heat enough to stay defrosted. 68 degrees i believe is the minimum so if its 70 its def got a issues with the coils not staying hot enough to stay defrosted. This will most likely require replacement. Especially if you have cleaned coils and still freezes. Try it in different room. If persists most likely a sealed restriction. Replace.

Dehumidifier frosts up


A dehumidifier will often frost up if room temperatures are colder than about 65 degrees F. If your room temperature isn't this cold, airflow to the unit may be restricted or blocked entirely. 1) Be sure the unit is set far enough from the wall so that airflow isn't restricted. 2) Clean the evaporator coils. To do this, unplug the dehumidifier and take off the outer cover. Allow excess moisture to evaporate from the coils. Then, using a brush attachment on a vacuum cleaner, remove all dust buildup. If necessary, cover the motor and electrical parts with plastic sheeting and spray with water.
