Dishwasher Leaking? All the Easy Fixes You Need to Know
If your dishwasher is leaking, it’s important to diagnose the problem quickly to avoid damage to your flooring or subflooring. The most common culprit for a leaky dishwasher is the door. When the door doesn't shut properly, water may leak out during a cleaning cycle. This could be as simple as an oversized dish pushing against the door, or it might require a part replacement. Fortunately, our friends at Sears PartsDirect have a lot of possible fixes to help you prevent a potentially costly mess.

Replace the Door Seal
One of the most common reasons a dishwasher might leak is due to a damaged or deteriorated door seal. Also known as a tub gasket, water usually leaks from the lower sides of the door if there is a breach in the seal. Find the source of the leak and examine the door seal around that area for visible signs of damage, in which case it should be replaced.

Replace the Water Inlet Valve
Also known as the solenoid fill valve, the water inlet valve is responsible for flowing water into the dishwasher throughout a cycle. If the water inlet valve fails to open entirely or at all, this will prevent any water from entering the dishwasher tub. On the other hand, water will fill the dishwasher tub even when it's off if the water inlet valve doesn't properly close. This may cause an excess of water to enter your dishwasher and cause a leak. If the water inlet valve is not opening or closing correctly, it needs to be replaced.

Replace the Drain Line
Also known as the drain hose, the drain line carries water out of the dishwasher tub at the end of a cycle. If there is damage or deterioration to the drain line such as a hole or a tear, water may leak out when the tub is draining.

Replace the Door Latch Assembly
If you close your dishwasher tightly but it's still leaking water, it might be that your door latch has become damaged or defective and is not properly holding the door shut. Examine the door latch assembly for signs of damage, and replace it to keep the dishwasher door closed during a cycle.

Replace the Drain Pump
First, check the drain hose, sink drain and sump to ensure nothing is blocked. If the path is clear yet your drain pump is continually failing to pump out water, the pump has failed. If you notice that your drain pump has visible signs of damage including cracks or dents, or if it has failed, it needs to be replaced.

Replace the Heating Element
The heating element is responsible for heating the dishwasher tub, which works to both get your dishes clean during the cycle and dry at the end of it. Examine your heating element for visible signs of damage or disfunction. If you don’t feel much or any heat from your dishwasher during or at the end of a cycle, check for any faulty wiring, issues with the control settings or a blown fuse in the heating circuit.

Replace the Overfill Float Switch
The overfill float switch helps to prevent too much water from entering the dishwasher tub by rising and lowering to detect the water level. When water gets to a certain level, the overfill float switch shuts off power to the water inlet valve to prevent additional water from flowing inside. A malfunctioning overfill float switch could allow too much water to enter the tub and cause a leak. The overfill float switch is located underneath the dishwasher tub and is connected to the mushroom float located inside of the tub. The mushroom float might be working properly, but the overfill float switch still could have failed. In that case, it needs to be replaced.

Replace the Pump and Motor Assembly
There are many different reasons why a pump and motor assembly might not be running properly. If your dishwasher has a damaged impeller or pump housing, this could cause the motor to fail to produce adequate water pressure through your dishwasher’s spray arms. If the motor on the circulation pump fails entirely, your dishwasher may fail to run at all. Seals inside could also deteriorate over time, which could also cause your dishwasher to leak. In any of these scenarios, it’s best to replace the pump and motor assembly.

Replace the Water Inlet Assembly
The water inlet assembly receives water from the water inlet valve and directs it toward the inside of the dishwasher tub via an open vent. If the hose that connects the water inlet valve and water inlet assembly or the vent leading to the dishwasher tub is clogged, clear them out to allow water to freely flow into the tub. If there are signs of damage to the water inlet assembly, it should be replaced.
Replace the Door Hinge
The hinge that allows you to open and close your dishwasher door is attached to a spring. If the hinge is damaged, you won’t be able to easily open and close the door, which might allow water to leak through during a cycle. Replace the door hinge so the door properly shuts.
