I have a Kenmore Dehumidifier (model 580.54501) that has been working
dutifully in my basement for several years. It suddenly stopped
working a couple of days ago. The problem was that the "bucket full"
LED was slowly flashing (once every 1 or 2 seconds), and the motor did
not run. The humidity display was showing "01". It was definitely not
the bucket, because it was empty, and was properly placed. I even
removed the bucket and pressed the water level control switch all the
way in, the bucket full LED was still flashing. If I unplug the power
cord, and plug it back in, the unit will come back to life for about
10 seconds. During this period, the fan is turning and the humidity
display indicates 45. Then the fan stops, the humidity display goes
back to 01, and the bucket full LED starts to flash again. Has anybody
had this kind of problems before? I wonder whether this is a water
level control switch problem or a control circuit problem. Is there
any test I can do?
