My Dishwasher Is Leaking From the Front of the Bottom of the Unit

Overfilling

• Your dishwasher has a small tub at the bottom that fills with water to help clean your dishes. This tub will occasionally fill too high, known as overfilling, and spill water out the bottom of the dishwasher. This is most likely the result of a faulty float switch. A rubber float is used in the dishwasher that rises with the water level and activates the float switch when it reaches a certain point, which shuts off the water. A suspected broken switch should be tested by a technician and replaced if it proves faulty.

Main Tub Seal

• The main tub seal is found at the bottom of the tub and is a rubber o-ring used to keep water out of the motor's shaft. The motor is responsible for turning the arms that spray hot, soapy water on your dishes. Inspect the seal, which is found at the center of the bottom of the tub, for cracks or other signs of degradation. The dishwasher will leak from the bottom if the seal is broken in any fashion. You will have to remove the racks, the spray arms and the impellers in the motor to get to the seal and replacement could require the work of a professional technician.

Door Seals

• There is a thin strip of rubber around the dishwasher's door that seals it from the inside known as the door gasket. This gasket could degrade over time and lead to a broken seal. The water from dishwasher may escape through the gaps in the seal, drip down to the floor and pool around the bottom of your unit. Check the rubber seal for solidarity and if it's damage you may need to strip it off and replace it.

Inlet Valve and Hoses

• The water has to get to the dishwasher somehow, and it does this with the help of special hoses and a water inlet valve. Torn hoses could leak water underneath your dishwasher while a faulty inlet valve could flood your kitchen. The inlet valve is responsible for controlling the flow of water into your dishwasher, so if it gets stuck open, the water will overfill the washer's tub and pool onto the kitchen floor util it is manually turned off. Have a professional technician inspect the inlet valve and hoses if you keep finding water on your kitchen floor.

Spray Arms

• The spray arms spin and toss water about the dishwasher's chamber with small holes running along their tops. A damaged spray arm may have a hole in the bottom, however, perhaps if it became chipped stray utensil that got stuck underneath the dish rack. The arm will spray water below and possibly out through the bottom door of your dishwasher. Check the spray arms for damage regularly and replace them with the help of a technician as needed.
