Hi,
After I press the wash button, then press start, I can hear the water sound, after 30 seconds, the dishwasher hums a few times like it's stuck, and automatically goes to drain mode. Then it finishes.
The wash cycle never goes in action. What part need to be replaced?
Thanks

Hi Cynthia, thank you for getting in touch. Based on our understanding, the issue could be with the circulation pump, part number PS11750859. It delivers water to the spray arms to clean the dishes. You may need to replace it to fix the issue. We hope this solves your problem!
Pulled dishwasher from under counter, attached link to spring, hooked spring back into frame/chassis, threaded link through pulleys, attached other end of link onto door, reinstalled dishwasher under counter. All's well. Note-I purchased an extra link anticipating that the other one will fail. They're cheap enough.
Caviat: The actual repair is less than 15 minutes, but I spent a lot of time playing with it before I figured out it was that easy and fast. You don't need to remove the dishwasher from the counter to do this. And it will probably help to look at the new part closely so you can understand where the retainer clip is to press it and release
... Read more the old pump.
First remove the water from the dishwasher pan that would not drain with a wet/dry vac. Otherwise the water will all drain on the floor when you remove the pump. Then remove the two screws on the kickplate on the front of the unit below the door. Remove the kickplate/maintainence access cover. The drain pump is on the right about 8 inches in. Using two hands you grasp the drain pump with your right hand and use the left hand to push the retaining clip down. Then the drain pump will rotate 1/4 turn counterclockwise and can be removed without pulling the dishwasher out. There is likely to be some water leak out that was traped in the pump housing that you can not reach with the vac. Disconnect the wire. Connect the wire to the new pump, put it in place and 1/4 turn clockwise to install it. Replace the kickplate and you're done.
Rather than remove the pump assembly - as an earlier post had done - I pulled the entire dishwasher out and laid it down on the floor. This allowed easy, direct access to the motor (that was the hard, messy part). From this point it was easy. Unplug the wiring, remove the retaining bolt, rotate the motor off the mounting brackets and pull
... Read more it out. Then put the new one in. That was the easy part (about 15 minutes). The entire job took 2-and-a-half hours, most of which was taken in disconnecting, cleaning up and reconnecting the dishwasher. It's much quieter now.
