Lg MBJ32856401 Switch Cam OEM Part

This was a very simple repair. It was done in about an hour. It involves disconnecting the dishwasher, emptying the water from the inside, taking it out and flipping it over, and replacing the diverter motor. This repair is done on the underside of the dishwasher, nothing to disconnect inside (just remember to remove the baskets). It would be wise to order the motor seal and micro switch that goes with it as they are all cheap parts and easy to swap out during the procedure. Be sure to take pictures of what you disassemble in case you forget how they go back. You will have to reuse the plastic cam from the shaft of the old motor, or you can order a new one (note which side is up!).

Replaced the Cam Motor & Switch Cam with the help of a video that was made available with the parts from ApplianceParts.

The repair was simple. Unplug the wire, remove 2 screws, remove the diverter motor then do the same in reverse. It took all of 5 minutes. The bigger job was removing the dishwasher and reinstalling it. Doing the repair myself saved me a lot of money. I’m guessing a repair person would have cost me around $200.00, maybe more.

The bottom spray arm of the LG dishwasher was not working. Replacing the small and inexpensive diverter motor that channels the water to upper and lower spray arms fixed the issue. It was a quick and easy change. The motor was easy to get to after pulling the dishwasher out of the cabinet. There are many videos on line showing how to replace this motor. Also replaced the switch that monitors the motor position.
