My Danby DDR657EE shows P1 periodically also. So, I called Danby.

Danby's Consumer Help Line (1-800-263-2629) is always busy. So, I called their General number: 419-425-8627. The receptionist transferred my call to their Service dept. My call was answered in 2 minutes.

The Service Rep. described the following code for my dehumidifier model (DDR657EE):
P1 = Defrosting: the unit will go into Defrost mode periodically to ensure that the parts are working at the right operating temperature. It should be in Defrost (P1) mode for only a brief period of time. If the unit is in Defrost (P1) mode continuously for a couple of hours (or more), then you should call Danby Service for further assistance.

He had no documentation of a P2 code for my model.

He also described other General Codes (applicable to most Danby Dehumidifier/Humidifier models):
E1 = Not enough water
E2 = Not draining
E3 = Water temperature too cool
E4 = Overflow Switch activated
E6 / E7 = Problem with Temperature Sensor

So, if you see P1 periodically (for brief periods), then it would be normal.

Also, here is a link to Danby's FAQ page for Dehumidifiers (which answers some common questions):

I hope that helps.

P1 constantly goes on throughout the day. I do not know if I have the setting right or if the drain hose is connected properly.


First, the drain hose should not be longer than 5 feet and should be draining downward, with no kings or bends in the hose, The dehumidifier does not have a pump. It relies on gravity to drain the water.

As far as it running all day is concerned, some dehumidifiers have a "Constant" or "Continual" setting. Which means it runs constantly. Either while dehumidifying or defrosting. In addition, most Danby dehumidifier models are designed to have the fan run even when the compressor is not running. This is in order to circulate the air in the room and make the unit work more efficiently. This is a standard feature and cannot be programmed to stop.

Hope this answered you questions.

My Whirlpool AD40USL5 Dehumidifier is displaying P1 on the control panel. I am not able to find any information about this in the User Guide that came with my unit. Could you please tell me what this...


Here is a link to the Owners Manual for the model number you listed. However, it does not have a LCD display on the Control Panel, which would show the Error Code P1. This is a Kitchen Aid brand that was manufactured by Whirlpool with the AD40USL5 Model Number. This came directly from Whirlpool's website. Hope it helps you in some way.

I have another of their dehumidifiers, the MDF1-30AE. The first time the P1 came on, the unit stopped, because the filter needed cleaning. Recently P1 came on but the unit didn't turn off, and I had already cleaned the filter, so I phoned Midea customer service at 1-866-646-4332. The man told me P1 means it's in defrost mode and said to just leave it on and the P1 will eventually go away. It's been a while though....

P1 code displayed in LED


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.
