I'm writing this in the most general terms because the model #2200L does not show up in any list I have of Oasis dehumidifiers, but there is an Eva-Dry 2200 solid-state (Peltier Effect) dehumidifier.

First, make sure the plumbing to the tank is not leaking. If the water is dribbling out elsewhere and evaporating again, that defeats your purpose.

Second, make sure both the hot side and the cold side of the refrigeration unit are clean. If the hot side radiator (condenser in a mechanical unit) is clogged with dust, the heat builds up in the system and it is unable to cool the cold side (evaporator) effectively. If the cold side is too dirty, it will be insulated from the air flowing through and will not cool the air sufficiently to condense out the moisture. Also, check the fan(s) to make sure they are spinning at full speed and aren't loaded up with dirt.

If this all looks good, then you have a problem with the operation of the refrigeration unit. In a mechanical unit, it is probably a loss of refrigerant or a worn-out compressor.

In a solid-state unit, it could be a power supply failure (cheap parts, but some labor to diagnose required) or a degraded thermo-electric module (easy replacement but about as expensive as the entire unit). The power supply is more likely to fail.

I have a Delonghi DH250R dehumidifier.It make a clicking noise every now and then when it is turned on. Is it that the thermostat trying to kick in to start the compressor ? And the dehumidifier is not...


There are 5 basic, but solvable reasons for what you described. Please pay particular attention to numbers 1& 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. 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 none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps you to further troubleshoot & solve the problem. Thanks for choosing FixYa.

. What does P1 on the LED screen mean?


P1 indicates that the air intake filter needs to be removed and cleaned. Turn the unit OFF and Unplug it from the wall, before removing the filter. If you wash the filter in warm soapy water (dish washing liquid is fine), be sure it's thoroughly rinsed and dried, before reinstalling it. Never operate the dehumidifier without the filter installed. Once the filter has dried, reinstall it. Plug the unit back in and Turn the Master ON/OFF Switch to ON. If necessary, you can reset the settings, you originally had the unit set on.

Hope this helped you.

We can hear the fan running and then the compressor, but little to not water produced; sometimes we can hear it click on and then off; the fan seems to be running a lot...


You may have the humidity level set to high. Usually anything above 50%, will show little results, unless your house is flooded.. Turn the humidity setting to the lowest level that your humidifier has
and give that a try.

The fan runs a lot, because it's designed to almost constantly move the air around. That way, if the humidity level rises above the setting on the dehumidifier, it can sense it and the compressor will turn ON.

Hope this helped you. Please let me know. Thanks.

Didn't LG produce some bad Humidifiers several years ago and have a recall on not working units? I recall reading this in Consumers Reports. I bought one back then and it has not produced a drop of...


If has not produced a drop of water for several years, then it's not working properly. But, this may be a case of setting the humidity level to high. In other words, if you set it at 70% or Maximum, that's the humidity level that it will maintain, not remove. To remove humidity, the level must be set low (35% or Minimum).

To test the unit, based on what I just said, place it in the bathroom, set the level as low as possible and turn the shower on medium hot. Do Not turn the bathroom exhaust fan ON. As you leave, close the bathroom door. Return in 15 minutes, turn the shower OFF and check the bucket water collected. If there's any water in it, it's working fine. It was probably a case of the humidity level being set to high.

Hope this helped you. Please let me know. Thanks.

Santa fe dehumidifier running but not producing any condensate. No ice forming on the coils and filter is clean.


You should check if the compressor is running. Your description makes it appear that the fan may be running and the compressor may not be running.

There are many things that can cause a compressor to cease running:

Open defrost thermostat
Bad run capacitor
Low refrigerant charge (caused by refrigerant leak)
Bad compressor relay
Bad compressor overload
Bad compressor motor

Other things to check:

If the fan switch is set to "on" and the humidity control is set to a high humidity level, the unit may appear to be running, but the compressor will not operate. Check the setting of your humidity control.

If the dehumidifier is operating in a room with a high temperature and a low dew point (very low relative humidity), it may be unable to remove any more moisture from the air.

If you are not comfortable troubleshooting the unit on your own, call the manufacturer service department at 1-800-533-7533, EXT 8459. They are very helpful.
