The Culprits and Solutions for a Leaking Dishwasher

Learn about the causes of a leaking dishwasher.

Dishwashers are convenient for washing tableware. If you are constantly busy or have more plates than you can wash, having one saves you time and effort. However, what happens when that quiet is replaced by a dishwasher leaking water all over your floors? A broken dishwasher can be an inconvenience, especially if it’s causing a leak. Read on to learn the culprits and solutions for a leaking dishwasher.

A Faulty Gasket is Prevalent

A malfunctioning gasket is one of the most common culprits for a leaking dishwasher. The gasket operates along the machine door’s perimeter to generate a watertight seal when the door is closed. Unfortunately, the gasket won’t seal correctly if it’s damaged, loose, or dirty. Consequently, water will escape from the dishwasher door during the rinse cycles. Therefore, ensure you inspect for holes, cracks, or dirt. If your leaky dishwasher is loose or damaged, replace it. Or you can clean it with a cloth if it’s only dirt accumulation.

A Damaged Water Pump System

A damaged water pump system can also be another culprit for a leaking dishwasher. The water pump system is responsible for delivering water to the wash cycle and emptying it out of the drain. Otherwise, the moisture at the bottom of the dishwasher can accumulate if your water pump system is damaged. Moreover, your machine is leaking water from the bottom of the hoses, and the clamps on this system are broken or worn out.

Defective Water Inlet Valve

It’s vital to evaluate the valve that permits water into the dishwasher’s chamber for any problems. The water valve is typically on the water inlet hose in the back of your dishwasher. If this valve leaks, one of our technicians can replace it since it’s not repairable. Otherwise, the leak can worsen if not addressed. A common sign of a faulty valve is hearing running noises when the machine is active.

The Filter is Clogged

A leaking dishwasher can also signal that you have a clogged filter. Filters are designed to catch food particles before they end up in the drain, but water can overflow them, causing them to leak from the bottom of your appliance if they’re too full. Thus, it’s crucial to clean your filter regularly, as it can last up to 5 years with proper maintenance.

Impaired Float Switch

A dishwasher comes with a float switch to keep adequate water levels during the wash and rinse cycles. The float moves with the rising water when your machine is on. When the water reaches a specific level, the float switch activates, shutting it off. However, if the switch is damaged, the water level will rise too high. A better solution would be to replace the whole component.
