Says bucket full when it was not
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.
Machine would come on for a minute, then stop with message CR1
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.
bucket full light constantly blinking with error code 01 on the display
Unscrew and detached front and back panels, and inside framework holding the sheet metal to the body, after removing the sheet metal, unscrew the box enclosing the control board, use needle nose pliers to unhook the sensor module from the board and place the new sensor into the spots where the old sensor was connected (thermostat area, humidity Sensor, bucket switch, and control board). Close up the unit and your good to go.
unit would not continue to run after start up. I was getting a 67 code on the humidity level screen
Ordered the new humidity sensor. Removed the sides and top all one piece of the dehumidifier by removing several screws. Removed the cover of the electric circuit box 2 screws. Removed old sensor by unplugging the wires. Installed the new sensor plugged in the 3 wires put the electric box cover back on. placed the sides and top back on screwed them in and it works just fine.
bucket full light was blinking and dehumidifier would run for a few seconds then turn off
remove outer shell and control panel. take cover off off electrical connection box. remove old sensor from front of condensing coil along with wiring harness to temperature sensor and bucket switch and circuit board. reinstall new sensor in the reverse procedure. reinstall covers.
Replaced the sensor and solved the problem. I had a lot of difficulty with the case holding the circuit board,etc because no easy way to service. Seemes they could have made it easier with a removable panel. I actually cut the wires and re-attached the thermister later after routing. Did not use the other parts of the wiring.
Note: The error code and bucket full indication is a result of a malfunction in the sensor assembly (p/n 6877A30013M. To replace the sensor assembly, do the following: (1) remove rear panel; 2) remove the front panel cover and remove bucket; 3) remove main cover (covers center of unit); 4) Remove cover over PC board on top right side of unit looking at it from the rear; 5)unplug sensor assembly connect on the main PC board; 6) remove clip that holds the temperature sensor on the compressor output tube ( this is a very strong clip)(also take a small piece of emery cloth and clean the output tube where the clip was attached); 7) use a tapered tool to spread the clip, just removed to, allow the temperature sensor to be removed from the clip; 8) unplug the bucket full switch connector; 9) remove the humidity sensor from the evaporator coil (just a snap-on connection; 10) remove the entire sensor assembly that was just disconnect during steps 1) thru 9) and reinstall the new assembly using the previous steps in reverse order; 11)Plug the unit in and all should be a go!
