Pressure relief tube behind the collection tank ?? should it point up or down?? model DH 400P

You will need to disconnect the hose and replace it with a screw on cap that came with the unit. With that in place, the water will be diverted into the bucket. If you are missing the cap, you can probably find a replacement at Sears Parts Direct.Be sure you have the correct model number when searching Sears Parts Direct or before calling them.

I hope this helped you. Thanks for choosing FixYa.

There's a small gray nub attached to the plastic above it. Slide the tube onto it and it should fix your problem.

superstee - You're having to empty it because either the drain hose you have connected to the unit is clogged or the drain hole a the hose connection is clogged. Therefor, the water is drained into the tank, rather than the drain hose. Also, the drain hose would not be any longer than 5' and must drain down, as the dehumidifier does not have a pump. It relies totally on gravity.

Remove the hose and check it for clogs. If clear check the drain hose connection, using an 18" long appropriately sized Zip Tie. Carefully insert the Zip Tie and continue to push it in until you reach the bend in the tubing. Gingerly work past this bend, until the Zip Tie bottoms out or you run out of usable Zip Tie. The while slowly pulling it out, rotate the Zip Tie. This will dislodge the clog. As you reach the end of the Zip Tie removal, be prepared for some water to follow. CAUTION: BEFORE DOING ANY OF THE ABOVE TURN THE MASTER ON/OFF SWITCH TO OFF AND UNPLUG THE UNIT.

The above should solve the problem for you. Please let me know. Thanks.

It appears the hole or tube that drains water into the bucket is clogged. To unclog it, you will need an 18" long, plastic Zip Tie or something similar (No wire coat hangers, though) that will fit into the hole or tube. You will see this hole or tube, once you remove the bucket.

Carefully insert the Zip Tie and slowly push it in, until you reach the bend in the tubing. You will gingerly have to work the Zip Tie past this bend, until it either bottoms out or you reach the limit of usable Zip Tie. Slowly pull it back out while rotating it. This will loosen the clog. As you continue to pull it out, be prepared for some water to follow.

This should solve the problem. Hope it helped you.

My DH 304 is a hand-me-down so I don't have a manual but it did come with a hose attachment which is plastic tube with a threaded end to which you attach a hose. The other end of the tube goes through a hole in the back of the unit and then through a foam screen inside the unit to slip over the drain plug. Aligning the tube and the drain plug can be tricky; it is helpful to remove the bucket to see if you're getting the tube onto the drain plug. Once you have the tube attached to the drain plug, align the tube in the hole in the rear of the unit so that the tab on the tube is inserted into the slot at the hole in the back of the unit.

THE LOWER THE % SETTING, THE MORE MOISTURE THE DEHUMIDIFIER WILL REMOVE!!!
I have a Provic dehumidifier mainly to remove damp from walls in my 1900s terraced house ( 3rd DPC failed, another on its way). I've read a lot about the technical side and all I wanted to know was 'do i set it on the highest or lowest % to extract moisture from the walls'. I rang the Managing Director at Provic (his contact details are given on their website) who was very helpful. He advised that the lower the setting, the more damp would be removed from the walls and therefore the air, as the water passes from the wall into the air. My DH ranges from 40% to 70% so he advised me to set it at 40% in the worst affected room to remove as much moisture as possible from the walls. As the moisture is removed, the DH will collect less water and set itself to the correct level anyway. He advised me that when as much water as possible has been removed from this room and the DH % will not drop any lower, to move it to a more central position in the house, such as the hallway to then start setting the rest of the house to the correct humidity level. I set the DH to 40% and left it on overnight closing all doors to the affected room and removing containers of water such as a vase of flowers. When I got up in the morning it had switched itself off as it had already collected 3 litres of water! You do have to be careful not to over dry the air as everything, furniture and electricals, naturally needs moisture, but for a short term, quick drying solution, this level is ok.
Hope this helps!

You may have a older model that has a collector tank with a protruding tube on it. If so just cut the end off the tube and slide on a piece of clear 9.5mm internal diameter PVC / Rubber tubing suitable for a fish tank air / water pump and secure it with a nylon tie wrap.

Continuous external draining for newer models with clear collection tanks.
If the appliance is to be operated for long periods of time but you are unable to empty the tank, you are recommended to use the continuous drain facility.
• Drill the inside of the drain spout using a small drill bit. This is located behind the rear grlle in the lower centre of the opening.
• Fasten the rubber hose to the spout. For models without drain hoses supplied, we suggest you purchase a rubber hose around 2m long, with an internal diameter of 9.5 mm.
• Make sure that the hose is not higher than the spout, otherwise water will remain in the tank; also check that the hose is not twisted. N.B: Keep the rubber bung. You will need it to plug the hose or close the spout if you revert to draining into the tank

If you pull out the water collection tank the unit tag should be inside behind where the tank goes.

I only got as far as disconnecting the filter between the small water bucket and the pump. I was able to get the pump working again after I cleaned the water bucket and filter by flushing them repeatedly with fresh water. The lines after the pump contained cloudy water, but I figured since the pump was able to push it out past the pump already, it shouldn't cause problems this far down. It saved a lot of time and hard work not having to disconnet the rest of the tubing or take the water bucket off. I also realized if I disconnet the first water collection tubing from just under the front panel and point the open end down, all the water in the bucket flows out. This part is so easy to get to. Just pull out the big collection tank and it's right there on the left toward the back. I can do this every week! Maybe then nothing will sit long enough in the small water bucket to turn into any kind of filter-clogging material.
