D30 - Overview

The forums indicate that one solution for this problem is replacement of the sensor assembly, which is what I did. Upon switching the sensor assembly it DID work for one bucket full, but then went back to indicating bucket full when it isn't. Other fixes indicate changing the switch assembly, which I tried to do but the part has been discontinued. The only other item is replacement of the main computer, which the cost added to the cost of the sensor assembly would equal the cost of replacement of the appliance, so I won't go there.

Removed 4 hex head screws around base of metal housing and 2 screws on bottom front holding on plastic grating and one screw holding housing to switch plate at top front. Hinged grating on back just pops off. Removed two screws holding fan motor on. Unclipped wire terminals (2). Bolted new fan in place.

One hitch was that one of the little terminal connectors that came with this fan motor was too small, so I had to buy some the right size, and strip the wire and crimp one of those on.

Also, this fan motor is two-speed, and my old dehumidifier is one-speed, so, according to the very helpful instructions, I just taped off one of the wires (not the one I would have guessed--it has you replacing the red with the black and taping off the new red one).

Then reassembled in reverse order, of course.

The only other thing is just that this stinkin' thing was so expensive, but it works fine. It's been humming away for days now, and my basement is once again in the pocket, about 50 - 55% humidity.

And it was pretty easy.

Googled message to see that it was probably the sensor or the bucket full button. The bucket button is no longer made, but the sensor was available, so I gambled and bought it to try. We removed the outer housing and old sensor. then replaced new sensor putting it in same place and following the path of the old one to plug in wires. the whole housing had to be removed, could not just remove a section. Once replaced, plugged in to test, seemed to work. so replaced all the housing and screws. Unit is working again. Definitely worth the gamble, bc a tech would have been 3-4 times more expensive. My tenant was also confidant about being able to replace the sensor. After we did it, I think I could have done it too.
