Whirlpool Dishwasher Leaking From Bottom of Door:... | appliancefaults.com

Technical Background:

The dishwasher's MCU (Main Control Unit) controls the water fill valve and drain pump based on sensor inputs. Leaks can cause the water level to exceed the expected range, but the MCU will not directly detect small leaks. The door seal and sump gasket are critical components for maintaining a watertight seal. 120V AC powers the fill valve and drain pump.

Symptoms:

US homeowner observes water leaking from the bottom of the Whirlpool dishwasher door during operation. May also notice water pooling around the base of the dishwasher after a cycle.

Possible Causes:

Worn or damaged door seal
Loose or deteriorated sump gasket
Spray arm obstruction or damage
Excessive suds from improper detergent
Dishwasher not level
Clogged drain pump or filter

Solution:

1

Inspect the door seal: Look for cracks, tears, or debris. Clean the seal with a damp cloth and mild detergent. Replace if damaged.
2

Check the sump gasket: This is located between the dishwasher tub and the motor/pump assembly. Disconnect power at the breaker panel. Remove the lower access panel. Inspect the gasket for cracks or deformation. Use a 1/4-inch nut driver to remove retaining clips.
3

Verify the spray arms: Ensure the spray arms are not obstructed by food particles or damaged. Clean or replace as needed.
4

Test with proper detergent: Only use dishwasher-specific detergent. Avoid using excessive amounts.
5

Level the dishwasher: Use a level to ensure the dishwasher is properly leveled. Adjust the leveling feet using a 5/16-inch socket or adjustable wrench.
6

Check the drain pump and filter: Remove the lower spray arm and filter assembly. Inspect the drain pump for obstructions. Clean the filter thoroughly.
7

Run a test cycle: After addressing the potential causes, run a test cycle to observe if the leak persists. Monitor closely for the source of the leak.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel (LOTO - Lock Out Tag Out) before performing any repairs. This appliance operates on 120V AC, which can cause serious injury or death.

Prevention:

Regularly clean the door seal and filter. Avoid using excessive detergent. Periodically check the leveling of the dishwasher. Use a rinse aid to reduce sudsing.

Expert Tip:

Many Whirlpool dishwashers have a diagnostic cycle that can be accessed by pressing a specific sequence of buttons. Consult the service manual or online resources for the specific sequence for your model. This can help pinpoint the source of the leak by running individual components.

Frequently Asked Questions

•How do I properly level my dishwasher?

Use a standard bubble level. Place it on the top rack and adjust the front leveling feet until the bubble is centered. Repeat for the side-to-side leveling. Then, adjust the rear feet if necessary.

•How do I replace the sump gasket?

First, disconnect power. Then, remove the lower spray arm, filter, and any other components covering the sump area. Disconnect any wires connected to the pump motor. Remove the pump motor assembly. Clean the area where the gasket sits. Install the new gasket and reassemble in reverse order.

Use a powdered or pac-type dishwasher detergent specifically designed for automatic dishwashers. Avoid using liquid dish soap, as it can create excessive suds and cause leaks.
