Is your dishwasher noisy? Not draining? It could have a bad circulation pump and motor assembly. This free troubleshooting video shows step-by-step instructions on replacing the circulation motor and pump on Whirlpool, KitchenAid, Roper, and Kenmore dishwashers.
Tools Needed: Torx screwdriver, wrench, Phillips head screwdriver, flat head screwdriver, pliers
Your dishwasher has at least one motor. It is attached to a pump, which forces the water up into the sprayer arms. During the drain cycle, it also pushes the water out of the dishwasher...down the drain.
The motor is behind an access panel beneath the dishwasher. Some models have reversible motors, others don't. This particular motor is reversible, which means it is mounted vertically right in the center bottom of the dishwasher with the motor shaft pointed up. The pump is mounted atop the motor, then attached to the underside of the dishwasher. When the motor runs one way, the dishwasher pumps water up to the spray arms; when it runs the other way, it drains the water.
As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks.
If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.
If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If the motor hums but doesn't turn, it may need to be replaced.
Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.
If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.
Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris.
