Daryl - For model number AD40DSL1
October 13, 2023
It does not collect water anymore. Is there a filter in this machine?
Chris Boyle Profile
Hi Daryl, thank you for contacting us. Your model does not come with a filter. We would recommend checking the bucket water level switch, part number PS992307, to fix the issue. When the water level in the collection tank reaches a certain level, the bucket water level switch gets triggered and sends a signal to the control board. If it is faulty, the dehumidifier may not collect water. We hope this helps, good luck with this repair!

The Origional Humidistat Quit Working
10 of 17 people found this instruction helpful.
  • James from Silver Bay, MN
  • Really Easy
  • Less than 15 mins
  • Screw drivers
The knob one turns to set the humidity level was removed. The two screws holding the top on were removed. The top was lifted and swung to the side. After noting which of the two wires went where on the humidistat the wires were removed. Small flat screwdrivers were used to pry back the plastic retainers on one side of the original fai led humidistat. The new one was put in place, the two wires were reattached. The knob was replaced. The top was positioned and its two retaining screws replaced. A magnetic phillips screwdriver was handy but not necessary. Piece of cake! Someone with ten thumbs could do it!! Thanks for the prompt courteous attention to the returned erroneous part! Dealing with partselect. Com was a pleasure. . . . . . Thanks!! P. S. The dehumidifier works like new now!!

Taking the case apart and replacing the control unit was a piece of cake. And the part arrived the very day after I ordered it.
