This part is the door actuator for your dishwasher. It is made of black plastic and is approximately 3 inches long and 3 inches wide at its widest point. The door actuator is found in the control panel, and it releases the door latch when you lift the handle. If your current door actuator is cracked or broken, you may not be able to open your dishwasher door, or the door will not close properly. The dishwasher also may not be able to start, and if this is the case, you will need to replace it. This part is sold individually and is an authentic OEM part.
