DOES THE DEHUMIDIFIER HAVE TO BE SET TO THE CONTINUOUS SETTING TO DRAIN WATER THROUGH HOSE

I would suspect the float first, IF the unit is level. But it could also be blocked with gunk and you will need to check the drain holes. I have always found a guitar string is an affective clean out of drain lines and holes.

The orange light indicates that your bucket is full, so if it isn't then it is most likely the float above.

I had the same problem with the LAD 704 DUL.....I tilted the unit back slightly with a wedge under the front side and the water is now draining through the hose into my drain....

SOURCE: why doesn't dehumidifier drain through hose? Even

I had the same problem....raised the unit 3 feet off floor, the drain hose is 4feet long... But the secret to getting unit to drain into hose if unit is set to Continous is...... TILT the unit back about 5 degrees with a half inch piece of wood under front wheels and She will drain into hose instead of bucket.... [email protected]

I have a similar model. There are two drains, one for the hose and one directly into the bucket. The hose one is supposed to be lower, but I had to put a 3/8 inch block under the right side of the unit to get the water to favor the hose instead of the bucket. Another possibility is that the far end of the hose is higher than the near end. If you can't lower it, you can put the whole dehumidifier up on blocks. One other thing to check is that the hose has a rubber washer in it where it connects to the unit. Use a tissue to see if this connection is dry. If it leaks, it will just drip into the bucket.
Good luck!
