How Do I Prevent a Dishwasher From Leaking?

A leaking dishwasher can typically require little effort to resolve. Many people can fix the problem on their own, whether due to a faulty gasket or simply overloading the dishwasher. We have compiled a few tips on how to fix common causes of dishwasher leaks below.

The easiest way to prevent a dishwasher from leaking or malfunctioning is to avoid overloading it. Ensure that dishes are arranged in an organized fashion before running a cycle. Additionally, remember to double-check that the dishwasher detergent is the correct one for the type of dishwasher you have.

If your dishwasher leaks from the door, it is likely because the door seal is loose. To fix this, tighten the screws around the dishwasher door. It’s also possible that your machine may be unleveled and requires setting to ensure it is leveled with the ground. You can do this by using a dishwasher leveling kit.

Ensure that the door gasket is tightly screwed in before reusing your dishwasher.

Replacing the dishwasher door gasket is a common solution to repair a broken dishwasher. If you have noticed that your dishwasher gasket is damaged or requires immediate attention, your best bet is to replace it. Always ensure the appliance is not running before removing the old door gasket. Then, take the new one and install it at the top of the door area. Don’t forget to read your dishwasher manual for specific instructions on how to replace the gasket.

Another tip to further prevent leaks is to replace the dishwasher drain hose. If your dishwasher’s drain hose is cracked or damaged, replacing it with a new one may be necessary. Consult your dishwasher manual for specific instructions on how to do this. 

Even if there is no obvious wear, replace hoses every five years. Use a reinforced steel-braided hose, as they are less likely to fail.

If your dishwasher continues to cause problems, consider replacing the drain pump. It may be defective. The dishwasher’s filter traps food particles that aren’t flushed down the drain during a wash cycle, preventing them from damaging the drain pump. However, if the filter isn’t cleaned regularly, it can become clogged with these particles. When this happens, water won’t be able to drain and will puddle inside, resulting in a dishwasher leaking from the front. Cleaning the filter should quickly fix the issue. 

Will a Dirty Dishwasher Cause Leaking?

Take the time to clean out your dishwasher. Dishwashers can gradually become clogged with food, grease, and other debris. When this happens, water can back up and leak out of the dishwasher. Cleaning your dishwasher often can help prevent this from becoming an issue.

To clean your dishwasher, start by running it empty on the hottest setting. Then, add a dishwasher cleaning tablet to the detergent dispenser and rerun the dishwasher.  If you have a particularly dirty dishwasher, you may need to deep clean it with a vinegar solution. To do this, mix equal parts of water and white vinegar and pour them into the dishwasher’s detergent dispenser. Run the dishwasher on the hottest setting and let the vinegar solution work its way through the dishwasher. 

By following these tips, you can help prevent dishwasher leaks and keep your dishwasher running smoothly for years to come. Remember, whatever the repair, reconnect the water supply and turn the power back on before resuming use.
