Examine the dishwasher door seal

Replace the door seal if you find it worn or damaged.

Inspect dishwasher spray arms

The leak could be caused by a blocked, clogged or cracked spray arm. A loose feed tube for the upper spray arm could also cause the leak. These problems can create a wave action inside the tub. The wave action will slosh water over the front lip of the tub and leak out the bottom of the door.

First open the dishwasher door and check that no dishes are blocking the spray arm so it can’t rotate fully. Load dishes properly so they won’t block spray arm rotation and cause leaks.

Check the spray arm for clogs and cracks or damage that prevent proper spray arm rotation. Clear clogs from spray arm hole using a bamboo skewer. Replace the spray arm if it’s cracked or damaged.

If the spray arm can rotate fully and isn’t cracked, check the spray arm feed tube connection on the pump’s water outlet opening.

Spray at a loose connection can create extreme wave action and a water leak.

To check the connection, open the dishwasher door and remove the bottom dishrack. Release and remove the bottom spray arm.

Reconnect the feed tube connection if you find it loose or disconnected.

Tighten circulation pump cover screws if you find them loose

Some Kenmore dishwasher pumps have an outlet that screws on top of the pump. If you have this type of dishwasher, make sure those screws are tight. The screws in this type of pump can work loose over time. When the screws get loose, water shoots through the side of the pump outlet, creating wave action that can cause a leak.

Tighten the pump cover screws if you find them loose.

Check the water supply line and drain system

Follow these steps to check to check connections and components under the tub for leaks:

1. Disconnect electrical power from the dishwasher by unplugging the power cord or shutting off the house circuit breaker for the dishwasher.
2. Take off the bottom front service panel and toe panel by removing the mounting screws and then pulling off both panels so you can see under the tub.
3. Check the water supply line connection at the front of the dishwasher. Tighten the water line connection if it leaks. If tightening the connection doesn’t fix the leak, shut off the water supply and place a towel under the water supply line connection. Disconnect the supply line and replace the connection seal.
4. Check the drain hose connection to the drain pump for drips or other evidence of leaking such as a water trail or water stains. Reconnect the drain line if it’s loose.
5. Use a flashlight (or your cell phone light) to look under the dishwasher for evidence of leaks. You may see the water dripping or a water trail indicating the location of the leak. If you find the source of the leak, replace the leaking seal or component.

If you can’t find the source of the leak on your own, schedule dishwasher repair service and we’ll send a Sears Home Services technician to your home to find and fix the leak.
