Causes and Solutions for Dishwasher Leaks

Water on the floor signals dishwasher leaks, and troubleshooting a leaky dishwasher is something even the most inexperienced person can do. Learn to spot the difference between a simple fix and an expensive dishwasher leak repair, and you'll save money on service calls.

Problem: Several drops of water appear on the floor after the cycle has finished.

Solution: It's natural for water vapor to condense on the door, then fall off onto the floor. Wait to open the door until the condensation has evaporated to avoid a damp floor. You can also wipe off the condensation with a dish towel.

Problem: Water on the floor underneath the dishwasher.

Solution: The problem could be the hose if you see water emerging from underneath the dishwasher. A hose connection can work loose over the years, or hoses can become damaged or cracked. Replacing a hose is very simple; it requires clamps on each end to keep the connection tight.

A water inlet valve can also cause excess water to spill out. The valve controls how much water comes into the dishwasher. If it is not working correctly, the valve could be stuck open, allowing too much water in, resulting in flooding.

Problem: Water is leaking from around the door.

Solution: First, look at the door latch to ensure it is closing securely. If it becomes bent or damaged in any way, it may not seal properly, which allows water to escape. New latch systems can be purchased and installed for leaking dishwashers.

Inspect the door seal to see if any of it is pulling away or cracked. A new seal is a fairly easy repair. The machine may also be filling too high. Inspect the water float (a plastic tube in the base of the dishwasher) for clogs or damage.

Problem: Everything has checked out, but the dishwasher still leaks.

Solution: Are using dish soap before you put dishes in the dishwasher? Soapy residue from dishwashing liquid can bubble up in the hot spray. The thick suds cause the spraying arm to get stuck, potentially spraying right at the door seal. The seal cannot hold up to constant pressure, so it gives, causing a leak onto the floor and creating occasional leaky cycles. Avoid using dish soap before loading the dishwasher to solve the problem.
