Amazon.com: Questions And Answers: WHAT DOES THE P1 error code mean??

Amazon.com, Inc.Oct 19, 2014 - Hi David, According to the manual: "P1- Unit is defrosting-- Allow the unit time to automatically defrost. The error will clear after the unit self ...

Empty the bucket. Reseat the bucket carefully or the code will not reset. This is the only documented action for code P1.

t appears to mean "defrosting." In other words, the condenser coils have gotten too cold and are icing up..


The filter is probably full, or the thermostat is faulty. Open it up and clean the filter first.

According to the manual, this code, P1, means that it is in a defrost cycle. I now have the problem that my unit is in the P1 mode as often as it is in the dehumidification mode.

Hi Mike

P1 is air probe faulty

P1 is code for defrosting. Once it's done defrosting it should start operating

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....

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 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

I hope that helps.

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

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.

I heard that the code P1 meant defrosting mode, and it will restart normally after it is done defrosting.
