Whirlpool AD50USS0 Dehumidifier Empty / Adjust Bucket LED is continuously on. Upon being plugged in, my dehumidifier comes on, works for about 2 seconds and then shuts off leaving the Empty / Adjust Bucket light on, and it's completely empty. It will not run if I hold the button in with my finger, nor will it run when I bypass the switch. Online forums say it's probably the switch, but that doesn't appear to be my issue. Am I missing something?
