Found the instruction book and by reading the setting it allowed the machine to shut off before it freezes up.

Thank you.

What is wrong with a Westpointe dehumidifier when it stops removing water and displays P1? It will run this way for hours and kick in and work briefly once in a while on continuous.


Usually the P1 error indicates that dehumidifier needs to be defrosted. The unit has detected ice build-up on the condenser coils.

Unplug the dehumidifier for several hours. Then plug it back in. If the problem recurs, check that the fan that blows air across the coils is working properly. Make sure that the room is not colder than the operating range of the dehumidifier. If the problems continues to occur, you may have a refrigerant leak in the system. That will require a service call to repair the dehumidifier.

If the unit is under warranty, contact Westpointe. The manual I have for a Westpointe 65 PT dehumidifier, https://www.appliancefactoryparts.com/content/pdfs/136333-1.pdf, indicates the unit is covered through year 5 after purchase for a refrigerant system. For Warranty service, the contact point is Midea Consumer Service at 1-866-646-4332. If the unit is not under warranty, consider whether to replace the dehumidifier.

I hope this helps.

Moisture collecting at the top front when running, even at mid power, over the control panel, sometimes turns to ice. if I shut it off when it is doing this the problem stops for awhile


Well, sounds like you have a good cold section in the dehumidifier-- that is good!-- But I agree-- we don't want water condensing on the surface-- and we surely don't need it turning to ice!
A couple questions to help us get to the next level of trouble shooting this problem:
1.) How cold is the room you are running the dehumidifier in?
(Obviously-- the warmer a room is, the easier to remove moisture--
the colder the room, the easier to drop the air temperature well below the freezing point-- making ice.)

2.) Have the air filters been cleaned/changed recently?
A dehumidifier needs a steady fast moving supply of air across its whole condenser/evaporator surface, in order to remove the maximum amount of water from the air, and not freeze up. (I would winder if something isn't blocking the flow of air toward the top of the coil?-- so that the coil in that area is going well below freezing temperatures, and thus allowing water (or ICE!) to develop near the top of the coil?-- Can you check air flow for us?

3.) You have suggested a good solution,-- especially if the above problems can not be easily corrected: Turn off the unit every few hours, and allow the warmth of the room, to defrost the coil....
In fact-- just to make sure that the air flow is not being restricted by ice deep within the coil-- let it stay off over night-- or bring the dehumidifier into a much warmer room, to make sure no ice is still blocking air flow deep within the coil..

Let us know what you learn about air flow, and get back with us-- THen maybe we need to take the trouble shooting deeper insicde the device.

I hope this helps-- MB

Our dehumidifier has formed a sheet of ice amongst the coils and will no longer pull moisture from the air. The hole from which the water drips is completely iced over. It is 70degrees in the room and...


Turn the unit OFF and unplug it from the wall. Allow it to thoroughly thaw and remove the humidifiers cabinet to expose the cooling coils. Clean those thoroughly and coat with a very light coating of WD40. Reassemble the humidifier and turn it ON. Set your humidity control at 50% and allow the unit to run for at least one hour. Check for water collection in the bucket and for any signs of icing, after one hour. If water is in the collection bucket and no signs of icing, lower the humidity to 45% and continue. If you not any signs of icing, watch the unit, as you need to know if it automatically goes into defrost mode. The compressor should shut off, but the fan will continue to run until defrosting is completed. If it doesn't the auto defrost sensor has failed and will need to be replaced.

Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks.

Compressor runs continually and cooling coils ice up but it doesn't defrost.


probally has lost some charge on the refrigerant. Low charge will ice the coil. Unless you are operating this at low temperatures. The ones I have seen do not have a defrost on them

Condenser coils do not freeze, it is the evaporator coils that freeze. If it is icing up then the setting is too low for the area it is in, basically the humidistat will never be satisfied so it will run continually and end up freezing the evap coils, the coils could also freeze if the filter is dirty or there is an air flow problem.

Most dehumidifiers these days have a built in defrost control, which turns the compressor off when the coils frost up while the fan continues to blow to help melt the frost off, so if it is frosting you may need a new defrost control, but first check the following: If your model has an air filter, clean it, as restriction of air flow will contribute to icing. Try to move the unit to a warmer location. Usually the best way to do this is to get it above the floor as far as possible, as the air temp is warmer closer to the ceiling than it is at the floor. Make sure there is plenty of room for air to circulate. (don't push it against a wall)
