Question about Whirlpool 75-Pint Dehumidifier

1 Answer

Unit is repeatedly freezing up

Whirlpool AD75USTO dehumidfier. I use a drainage hose, but noticed that nothing was coming out. The hose was flushed and the filter cleaned, but still no water production even with the hose disconnected. This unit is less than 2 years old. The fan is running constantly, but I get ice formed on the right side of the unit. Apparently, the coils are freezing rather than emptying water either into the bucket or drainage hose.

Almost all dehumidifiers now have automatic defrost, but if you are seeing frost is just one small area, it means there is a refrigerant leak. Check your warranty to see if the sealed system is covered longer than one year. Generally, if it is, most manufacturers will replace the unit (rather than repair it, as the repair is rather expensive compared to the cost of a new unit). If you do not have any sealed system warranty coverage left on it, don't fix it. Buy a new dehumidifier.

Why does Coil keep freezing up.

Your dehumidifier may be set incorrectly for the ambient humidity level. The coil has to defrost periodically to allow drainage and maintain efficiency.

Whirlpool AD70USR0 Dehumidfier - Our basement is extremely humid and the dehumidfier sounds and looks like its running but collects no humidity...any suggestions why?

If it is very cold some of these consumer units will not turn on the compressor. If the unit suddenly stopped working and the temperature is room temperature I would guess a refrigeration issue- either a leak or bad compressor. Make sure the "full bucket" indicator light is not on- the condensate bin may not be plugged into the unit properly.

Dehumidifier AD75USTO Whirlpool. Taking in air but not taking out moisture.Seems to be frozen up inside, etc. Can I get a manuel?

Sorry, but your Model # doesn't match any Whirlpool Appliance in my data base. However, another company may have bought the rights to use the Whirlpool name on house brand that they sell. But, lets get to a solution to your immediate problem.

First turn OFF the MASTER ON/OFF Switch and unplug the unit from the wall outlet and allow the unit to completely thaw, before removing and cleaning the air filter. As, I suspect, the filter is dirty and may be clogged. Historically, this is one of the things that can cause a dehumidifier to struggle and not be able to keep up.

After you remove and clean the filter, remove the water collection bucket and look for the drain tube or hole that drains the water into the collection bucket. Using an 18" long plastic Zip Tie, that will fit into the drain hole or tube. Carefully insert the tube into the drain hole. Continue to push it in and you'll reach a bend in the tubing. Carefully push it past this bend, as far as you can. Then, while rotating the Zip Tie, pull it back out slowly. Be prepared for some water to follow. One word of caution - DO NOT use a wire coat hanger to clear the drain tube.

Reassemble everything and you should be good to go. If however, the unit freezes up again, the compressor may be low of refrigerant gas and it will need to be recharged.

Hope this helps you continue to troubleshoot and solve the problem.

I have a Whirlpool Gold dehumidifier with the hose set up for direct water release into a sink drain. I assumed once you hooked up the manufacturer hose provided it would be a direct drain process and...

I have a similar Whirlpool dehumidifier and a similar problem. Have you tried setting it to continuous mode? My understanding was that it would only divert the drainage to a side hose when in the continuous mode.

Haier 30 pint dehumidifier continuous drain problem.

Many just attach the hose at the reservoir; from your description, Haier apparently has a separate location. Check that the point that the hose attaches has an opening (many don't, they expect you to drill it). It should then drain through gravity. Check to make sure that no part of the drain hose is higher than the bottom of the reservoir, otherwise it can't drain. It won't siphon because each time the the tank empties, the suction is broken and the siphoning can't continue.

Check the point on the tank (Bucket) where the hose connects to. Make sure there is no obstruction at the outlet of the bucket to the hose connection. Next make sure the hose has no kinks or no loops that may trap air to the drain. If necessary for a long run to the place of drainage raise the dehumidifier to a higher level for better drainage.

Whirlpool Dehumidifier (AD75UST) blows water out upper right vent? Whirlpool Dehumidifier (AD75UST) is blowing water out of the upper right vent. Details: *Approx. 5 years old *It continues to collect water and work "normally" except for the water blowing out of the vent. I have attempted to collect water using the bucket but it continues to blow water out of the upper vent. I have also attempted to drain water through the hose attachment but, again, it continues to blow water out of the upper vent. *It is on a level surface *I have cleaned the filter in front to no avail. *The unit is run in 600 sq ft basement about 6 months out of the year on a continuous basis for the following reasons: The home is located in an area that was once a swamp. Therefore, it gets quite wet in the spring/summer. The basement/foundation is about 100 years old and has issues with seepage and water often pools in various areas when there is consistent and/or heavy rain. *I also checked the troubleshooting section of the manual but it didn't mention an issue of this type. *I have searched the web in hopes of finding a solution but have been unable to find anyone else with this problem (perhaps I'm using the wrong terminology? I'm only guessing the part that is blowing water is called a vent). *The warranty on the interior/sealed system is due to expire next month (end of April 2012). I'd like to narrow down the problem before that if it happens to be an issue that Whirlpool with pay to repair. Any ideas on how to correct the problem? Thank you in advance!
