A kitchen comes filled with valuable appliances. You’ve got the range oven, a refrigerator, a garbage disposal, and even a dishwasher. All these investments help you save time and money, especially when trying to manage your daily chores.

Although these appliances usually function as intended, there can be an occasional problem. When you look at the dishwasher specifically, it can spring an unexpected leak.

It might be tempting to call someone out to repair the problem right away, but the work could be something that you can fix in the next few minutes. Most of the leak culprits are issues you can address with simple DIY solutions.

Why Is My Dishwasher Leaking?

Before you start working on your dishwasher, you’ll want to take three steps.

  • Unload any dishes that might be in it.
  • Use towels to soak up whatever water might be on the floor or in your cabinets.
  • Unplug the appliance or flip the switch at the breaker.

If you have a leak happening when you run the kitchen sink faucet, that means you have a drainpipe issue to resolve. You must raise the dishwasher drainpipe above the skin drain level to solve the problem.

When the dishwasher starts leaking while it operates, here are the potential issues that you’ll need to troubleshoot.

1. Leaking Gasket

When the door gasket becomes faulty on a dishwasher, you’re almost guaranteed to see a leak happen while the appliance operates. This issue typically puts water on the kitchen floor in front of the unit.

If you see the gasket around the door is worn or torn in sections, it’s a good idea to replace that component before operating the dishwasher again.

2. Door Latch

If your door is loose while the dishwasher operates, there could be space between the gasket and the main body of the appliance. That’s enough room for water to escape! The only way to fix this problem is to replace the faulty part.

You might notice that the latch is bent because the door wasn’t shut quite right. In that situation, you can move the part back to its regular position to prevent future leaks from occurring.

3. Detergent Problem

If you use the wrong detergent in a dishwasher, it can create a mess that a gasket can’t solve. The most common issue in this category involves adding liquid dish soap to the appliance instead of something more appropriate.

Your dishwasher manufacturer should let you know what detergent is the safest to use in the appliance. If you’re unsure about what to put in to clean your dishes, choose an item meant for your make and model.

4. Hose Problems

When the water leak flows from underneath the dishwasher, you could have a valve problem or a hose issue. You’ll need to disconnect power to the unit before removing the toe kick from the front of the appliance. That’s where you can access the recirculation hose, water inlet valve, and other parts that might be leaking.

Carefully run your hand along the different hoses underneath the dishwasher to check for water or moisture. While you’re taking this step, it helps to look for corrosion, loose connections, or a malfunctioning solenoid.

5. Float Switch

When your dishwasher tub gets too full, the door is more likely to spring a leak. This part is meant to prevent the appliance from overfilling, but it can malfunction if it gets caught on something. You might need to clean everything out to ensure it works correctly. The mechanism might also require a replacement.

There could be a drainage issue contributing to this problem. You can check the dishwasher’s filter for clogs that could be preventing the appliance from sending water down the drain.

6. Sitting Crooked

Dishwashers must sit level to function as designed. If your appliance is crooked, you’re more likely to experience a leak. You can check on this problem by using a carpenter’s level on the rail where the rack rolls are for a front-to-back measurement. You can also set the tool when the door is open for a left-to-right reading. If it needs an adjustment, you can alter the leveling screws on the front legs with an adjustable wrench until it is no longer crooked.

When your dishwasher starts leaking, it can be a frustrating experience. Since a slow leak isn’t always detectable, it’s a good idea to inspect this appliance at least once per month to prevent mold and mildew development from happening in your kitchen.
