Had an issue with the water draining from the hose. Had worked before and stopped draining all of a sudden. Used a portable air compressor to blow it out. Went to the owners manual and saw that the drain outlet unscrews. Thought the drain hose was internal, taking the bucket off, then removing the drain outlet (2 screws, easy-peasy) Found the soft plastic drain line was kinked enough to stop/slow water from draining clearly. Plastic drain line needed to be heated with a heat gun/hair dryer with a metal file inside to restore the roundness of the tube. Keeping my fingers crossed.

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.

Make sure the filter is properly set in place. If it isn't, the system will treat it as a dirty filter.

On my particular model (Keystone KSTAD70A) the circular arrow button toggles the continuous mode. What this does is keep the dehumidifier running even after the target humidity is reached... this is particularly usefull when you are trying to dry out a room that got flooded (i.e. basement after a bad rain, or a bathroom that had a plumbing issue) before mold sets in... once that happens all is lost... :)

I can only assume that it would be the same function on most models.
