Four Common Reasons Why Your Dishwasher Is Leaking

Leaking dishwashers can be a pain to deal with. To make matters worse, this can be quite common as dishwasher hoses will eventually tend to leak due to constant usage. If your dishwasher is leaning, the first thing you need to do is to identify the cause. This can be rather tricky, especially if you know next to nothing about dishwashers. To help make things easier for you, we thought it would be useful to put together a brief article on this subject. If this is something that you’re interested in learning more about, read on for four common reasons why your dishwasher is leaking. 

Dishwasher Door Gasket

If you notice water leaking from your dishwasher door, the door gasket is likely the cause. To check, open the dishwasher door and inspect the gasket. If it’s cracked, torn, or otherwise damaged, it will need to be replaced. If the door gasket looks fine but you still have a leaking dishwasher, the problem may be with the door itself.

A dishwasher leak usually means the drain hose is clogged. This is the hose that carries water away from the dishwasher. It can get clogged with food, grease, and soap over time. When the hose is clogged, water can’t flow through and will leak out from under the dishwasher. To fix a dishwasher with a clogged drain hose, disconnect the hose and remove the clog with pliers. 

Dishwasher Pump Seal

If you think your dishwasher pump seal is leaking, unplug the dishwasher and remove the access panel on the bottom of the unit. Find the pump and look at the seal to see if there is any damage. If the seal is damaged, you will need to replace it. Dishwasher leaking usually means there is a problem with the rubber door seal. Over time, the door seal can become brittle and cracked, allowing water to leak out.

Water Inlet Valve

If water is leaking from your dishwasher, it may be due to a faulty water inlet valve. First, check the valve for any debris or mineral build-up. If it’s clean and there is no build-up, then the valve may need to be replaced. If your dishwasher doesn’t start, check for water leakage underneath it. 

Broken Float Switch

If there is water leakage, the float switch might be activated, telling the dishwasher that there is too much water in the tub. To determine if your float switch is faulty, remove the dishwasher panel and look for the switch. If it is stuck in one position, then you will need to address this problem. Unfortunately, there are very few things that you can do when it comes to a broken float switch. To fix this problem, you’ll need to clean or replace the float switch.


We hope this article proves to be useful when it comes to helping you figure out what’s wrong with your dishwasher. While a leaking dishwasher may seem intimidating, it’s not something that you should be overly stressed about. Once you identify the issue, you can take the proper steps to fix it. If it’s beyond your capabilities, make sure to call a professional as soon as possible.
