Leak Behind the Black Motor in a Kenmore Dishwasher

Loose Hose Clamp

• Underneath a Kenmore dishwasher are hoses that supply water and remove wastewater from the dishwasher. Several clamps secure each hose to various connection points in the dishwasher. It’s possible that one of the clamps is loose and causing water to leak from the dishwasher so that water is collecting behind the motor. Remove the bottom panel of the dishwasher; either lift it up or slide it off, depending on your model. Shine a flashlight under the tub to see if you can pinpoint the faulty clamp. Remove the clamp and reposition it securely to the hose where it came loose. If the clamp won’t secure properly, replace it.

Split Hose

• A punctured or split hose can leak water beneath the dishwasher, which could cause water to end up behind the motor. Remove the bottom access panel and see whether or not you can find the leaky hose; water is likely pooled around the leak spot. Disconnect the hose and install a new one or contact a repair service to have a technician replace the damaged hose and confirm that the replacement hose is installed correctly.

Cracked or Clogged Spray Arm

• A cracked or clogged spray arm or impeller can redirect water toward the bottom of the dishwasher. Due to the force of the water dispersed by the sprayer, you may find water leaking from the corners of the dishwasher during the wash cycle. Although leaks usually occur in the front, it’s possible for water to drip into the bottom cabinet where the motor is. Inspect the impeller for signs of damage. There should be no visible cracks on the arm. If you find cracks, replace it. Examine the spray arm’s holes to make sure they aren't blocked. Remove the spray arm by removing its center cap and turn the arm clockwise, then lift it off. If the holes are obstructed, use a toothpick, needle-nose pliers or a bristle brush to remove debris. Wipe the spray arm clean with a damp cloth or sponge when you’re done and install it back on the dishwasher.

Obstructed Float Switch

• The float switch is behind the motor on most dishwasher models, including many Kenmore dishwashers. It regulates the water level in the dishwasher. If it clogs, the appliance won’t clean dishes properly, and water can trickle from the switch area and puddle beneath the switch and motor. The float switch should slide up and down with ease when it’s working properly. Remove the bottom access panel. Try to move the switch up and down. If it doesn’t move, it’s probably obstructed or faulty. Clean it with a brush to dislodge any blockages. If the leak persists, contact contact a repair company to have a dishwasher repair technician verify that the switch isn’t defective.
