How do you hook up drain hose to model HDN455 RB

Remove the bucket and remove the plastic cap on the bottom of the bucket. Then take the rubber insert out of the cap and save it. You will use it later. Using the hose that came with the unit, thread it through the cap opening and add the washer to the cap. Screw the cap to the mating connector on the bucket. Be sure to use the washer or the connection will leak. Now, thread the hose through the round hole and extend the hose to the back of the unit. And finally, replace the bucket in it's original position in the unit.

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

Model HDN455

Check the coils at the back of the dehumidifier to see if there is any frost buildup on it. If there is, turn off the machine for a while until the room warms up and melts off the frost. The machine works by condensing the moisture in the air over these coils, so if the coils are frosted over, or are not cold enough, the moisture cannot condense. If the coils are not cold enough, you may want to get it refilled with refrigerant. You will need to take it in for servicing in this case.

Hope that helps! Should you have any further questions, please feel free to post them here.

P.S. - If you find that the solution/answer I provided led you to, or resulted in a fix, please close the ticket with a FixYa! rating. I would be very grateful for your show of appreciation.

Thank you for using FIXYA!

Haier HDN455 dehumidifier fan runs continuously but not compressor

First ! you are trying to use this dehum in cold weather conditions. this time of the year there is little humidity in the air. best conditions for the dehum to work will be when the temp. is 65 degrees or high, and the humidity is 60% or higher. if you don't trust what I said then take it to sears to be checked out.
