Dishwasher: Leaking

Don't ignore a leak from your dishwasher; water can quickly damage your flooring or subflooring. First, make sure the door is actually closing fully. Even if the dishwasher latches shut at the top, a dish pressing against the door or a misaligned hinge could create a small gap along the side of the door that lets water out. Other common causes include a worn door seal—also called a tub gasket—or a crack in the water inlet or drain line.

These repairs may help solve your Dishwasher problem:

Replace the dishwasher door seal

Door seal

Replace the door seal, or tub gasket, if you find water leaking from the opening to the tub. Water usually leaks from the lower sides of the dishwasher door when the tub gasket is leaking. The tub gasket can be damaged or worn out and is usually visibly damaged if it needs to be replaced.

Replace the dishwasher water inlet valve

Water inlet valve

The water inlet valve, also called a solenoid fill valve, controls the flow of water into the dishwasher by opening and closing. If the water inlet valve doesn't open at all, water can't flow into the dishwasher. If it opens partially, the dishwasher won’t fill adequately, and the water level will be low—a noisy pump is one indication that the water level is low. Conversely, if the water inlet valve won’t close, water fills the dishwasher tub even when the dishwasher is off. If the water inlet valve doesn't open or close correctly, repair or replace it.

Replace the dishwasher drain line

Drain line

Replace the drain line—also called the drain hose—if it develops a hole or tear. Holes in the drain hose cause the dishwasher to leak, especially when the dishwasher is draining.

Replace the dishwasher door latch assembly

Door latch assembly

The dishwasher won't start if the door isn't completely shut and latched. If the door doesn't latch shut, replace the latch mechanism. Even if the door latches fully, a problem with micro-switch in the door latch/switch assembly could keep the dishwasher from starting; in that case, replace the micro-switch.

Replace the dishwasher drain pump

Drain pump

Replace the dishwasher drain pump if it's cracked or damaged, or if the drain pump doesn't pump out water. Before replacing, check the drain path (drain hose, sink drain and sump) to make sure it's not blocked. If the drain path is clear and water doesn't pump out, the drain pump has failed. Replace the drain pump if it won't run even though it's getting run voltage from the timer or control board.

Replace the dishwasher heating element

Heating element

Replace the dishwasher heating element if it's visibly broken or not heating properly. If the heating element isn't visibly broke, check for a wiring failure, control failure or a blown fuse in the heating circuit before replacing the heating element—those issues could also be responsible for the heating element not working properly.

Replace the dishwasher overfill float switch

Overfill float switch

The overfill float switch is located under the tub and is attached to the mushroom float inside the tub, which rises and lowers with the water level in the tub. When the overfill float switch detects that the water level is too high, it shuts off power to the water inlet valve, stopping the flow of water into the tub. Even if the mushroom float is working properly, the micro-switch could have failed. Replace the micro-switch if it fails.

Replace the dishwasher pump and motor assembly

Sump and motor assembly

Several situations can require the replacing the pump and motor assembly in a dishwasher. If the motor on the circulation pump fails, then the dishwasher pump won't run at all. Sometimes the motor runs but doesn't generate water pressure through the spray arms, because the damaged impeller or pump housing is damaged. The pump housing and/or the seals could also deteriorate or become damaged, causing the dishwasher to leak. Problems inside the pump and motor assembly can create abnormal noises in the dishwasher. In all these situations, the pump and motor usually must be replaced.

Replace the dishwasher water inlet assembly

Water inlet assembly

The water inlet assembly is an apparatus that is mounted to the side of the dishwasher tub near the water inlet valve. It receives water from the water inlet valve and directs it into the dishwasher tub through a vented opening. If the vent or the connecting hose is clogged, then the inlet assembly will need to be repaired or replaced.

Replace the dishwasher door hinge

Door hinge

The dishwasher door hinge is attached to a spring. It pivots on a pin to allow the door to open and close in a controlled manner. If the door hinge is damaged, it won't allow the door to open and close properly. In that situation, replace the door hinge.
