The filter in your Keystone KSTAD70B is meant to be washed. It is not listed as a replacement part in the owners manual. This is copied from the manual:

3. Clean the air filter
Remove the filter every two weeks based on normal
operating conditions.
Remove the filter from the top of the unit (See.Fig.11a),
or to remove the filter,remove Bucket then pull filter
downwards (See.Fig.11b).
Wash the filter with clean water then dry.
Re-install the filter,replace Bucket. CAUTION:
DO NOT operate the dehumidifier without a filter
because dirt and lint will clog it and reduce
performance.

If you have lost or destroyed the filter, go to Amazon and order the Duck Brand 1285234 Replacement Air Conditioner Foam Filter, 24-Inch by 15-Inch by 1/4-Inch, 1-Pack for 96 cents with free shipping as an add-on item to any order. It is also washable so you will be able to use it like the OEM filter material.

Hi and welcome to FixYa, I am Kelly.
Per the model number you provided in your post (WDDH-820EAH) this is your user's Manual:
http://www.orientalpacific.com/backend/files/products/manuals/127/WDH-820EAH%20User%20Manual.pdf

Note the comment about air filter cleaning on the back of the unit every 2 weeks.
Thanks for choosing FixYa,
Kelly

if the temp of the area it is in is not too cold and the coils and filters are clean, then it may have deleloped a leak and lost some of the refrigerant charge. i would clean coils and filters first.

Hello,

follow the below instructions:

Turn off the dehumidifier machine and unplug it from the wall.

Lift the water bucket up and out of the dehumidifier.

Locate the filter located under the compartment that houses the water bucket. Lift the filter straight up and out of the dehumidifier.

Vacuum as much of the visible dirt and debris as possible.

Fill a sink half full with water. Place the filter in the water and allow it to soak for one to two minutes.

Wipe both sides of the filter with a wet sponge to remove any remaining dirt and debris. Rinse the filter with clean water.
Wipe the filter with a dry cloth to remove excess moisture. Allow it to air dry for approximately 30 minutes before inserting it back into the dehumidifier.
Good luck.

Pull out drain bucket, under lip of bottom front of cabinet (top of bucket area) remove blue tape and slide down filter, rinse or vaccuum off 1/yr.

Manual should be on line, but google full model number (sticker at rear of bucket area)

Several possible problems. Filter clean? As strange as this may sound you may have lost a little refrigerant. If problem persists after filter is cleaned, then a Tech needs to look at it.

Depending on the ambient temp/humidity and how its set it could definitely run continually. If you don't hear it it's possible the blade is broken or just stuck.
