How do i hook up plastic attachment so i am able to run a hose to a drain for continual usuage DH404E

Attach a length of garden hose no longer than 5 feet, to the threaded drain hose connection that was supplied with your unit, to carry water to the drain.
1. Remove the drain-hole cover on the back left side of your unit.
2. Connect a garden hose to the threaded drain hose connector.
3. Push hose connector tightly to the drain-hole on Rear Grille with the arrow on the tab pointing UP.
The hose attachment will accept a standard garden hose fitting.
Do not over tighten the hose when connecting it to the hose connector,
use a rubber washer and tighten by hand firmly without stripping the
plastic threads.
When being attached to hose connector drain hose connection,
do not bend or kink the hose. The hose should lie flat from the
dehumidifier to the drain.

First, the hose should not exceed 5 feet in length. There is no pump in that model dehumidifier. It relies totally on gravity to drain through the hose.

If all of the above is as stated above, I suspect that hose or the tubing inside the hose connecting is clogged. Which forces the water into the bucket rather than the hose.

To remove the clog in the unit, you will need an 18" long plastic Zip Tie or something similar, that is appropriately sized to fit into the hose connection/drain hole. NO wire coat hangers though.

Carefully feed the Zip Tie in to the hose connection. About 6" in the tubing will bend. You need to gingerly work the Zip Tie past this bend, until the Zip Tie bottoms out or you run out of Zip Tie to work with. The slowly remove the Zip Tie while rotating it. This will breakup clog. As you near the end of the Zip Tie coming out, be prepared for some water to follow. DO NOT perform any of this while the unit is plugged in to the wall outlet.

Hope this helped you solve the problem, Robert. Please let me know. Thanks.

The continuous drain hole (where the hose is inserted) is clogged. To remove the clog, you will need an 18" long plastic Zip Tie (or something similar. But NO wire cost hangers) that will fit into the hole.
Insert it slowly and push until you reach a bend in the tubing. You will need to gingerly work it past this bend until the Zip Tie bottoms out or you run out of Zip Tie. Then, while rotating it, pull it out slowly. As you reach the end of the Zip Tie, be prepared for some water to follow. Also make sure that the drain hose, when reinserted is not crimped and the end is lower than the drain hose connection. The unit does not have a pump. It relies on gravity to drain water through the hose.

Hope this helped you to solve the problem. Please let me know. Thanks.

Some dehumidifiers don't require that the bucket be in place, when a drain hose is attached to the unit. I'm not sure that's the case with yours, because I'm unfamiliar with the Westpointe brand. You should also check the drain connection that the hose is connected to. It may be clogged, which forces the water into the bucket instead of draining through the hose. If you have something flexible like a long plastic Zip Tie, that can easily be run into the hose connection and slowly pulled back out, while rotating it should loosen any clogs. Be prepared for water to follow. Do not use a wire coat hanger to do this and be sure the unit is OFF and unplugged from the wall, before attempting it.

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

No. The tube inserts straight into the drain hole. Follow the 4 sets below.

1. Connect a garden hose to the threaded drain hose connector.
2. Remove the drain-hole cover.
3. Push hose connector tightly into the drain-hole on Rear Grille.
4. Press the hose down and make sure the "Arrow" on the tab is pointing upward.

NOTE:
The hose attachment will accept a standard garden hose fitting. Do not over tighten the hose when
connecting it to the hose connector, use a rubber washer and tighten by hand firmly without stripping the plastic threads. Be sure the hose lays flat and has no kinks, as it will not drain properly.

Try to see if operating the float lever by hand can make it turn off the 'bucket full' message. Maybe use a rubber band or tape to keep it in the on position vs. the 'bucket full' off position.

Check to see if the bucket has to be inserted for the unit to operate, and if the bucket has a nozzle to hook a hose up to at the bottom. I have a dehumidifier of a different brand that has this feature that works with the bucket in, but with the drain nozzle on the bucket connected to a plastic tube that leads to a drain for continuous operation without having to empty the bucket.

How is your hose attached to the unit if it isn't attached to the bucket?

Good luck on this repair.

Yes a hose can be connected to this unit.

1. Remove the drain-hole cover from the back of the unit.
2. Connect a garden hose to the threaded hose connector.
3. Push the hose connector tightly to the drain-hole on the back of the unit

This is explained on the manual on page 12. Hope this helps

With most portable dehumidifiers use a bucket to catch the condensate. Then the bucket is full the dehumidifier stops, then you need to empty it and replace the bucket to get the dehumidifier to start working again.

To make this unit run continually, the bucket can be modified so a garden hose can be attached and the hose can be feed into a floor drain. To do this look at the bottom of the bucket, there should be a hose connector where you can attach a standard garden hose. You will need to drill out the center of the hose connector with a 1/4" drill bit. Then you can attach the hose to the bucket and the other end into the floor drain.

WHEN I BROUGHT MINE I HAVE A HOSE RUNNING TO A FLOOR DRAIN BUT REMOVE THE HOSE SEE IF THERE IS A PLASTIC COVER INSIDE WHERE THE HOSE HOOKS ON FROM THE FACTORY THE CONDENSATE PAN IS MENT TO HOLD WATER AND THIS PLASTIC PIECE HAS TO BE REMOVED FOR HOSE USE

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.
