Fixing A Leaky Dishwasher

Why Is Your Dishwasher Leaking

No one wants to walk into their kitchen to find a puddle of water coming from their dishwasher. If you have found that your dishwasher is leaking, you may be worried that there are all sorts of catastrophic problems with it

But do not worry, today with a bit of instructions, tools, and parts you can save yourself hundreds from hiring a repairman.

Reasons For A Leaky Fridge

Reason #1: There is a problem with the seal

Perhaps the simplest place to start when you realize that your dishwasher is leaking is to look at the gasket seal. This is the seal which surrounds your dishwashers door used to prevent water from leaking.

Sometimes it dries out overtime These are typically made of either vinyl or rubber, and over time, they can begin to dry out. They lose their flexibility, and may even crack. Without a watertight seal, the water is then free to drain all over the floor. You will need to inspect the gasket to make sure that it is not damaged, cracked, brittle, worn out, or otherwise misaligned.

Reason #2: There is a problem with the float

Dishwashers have what is known as a float switch within them, which is used to make sure that the system does not become overfilled with water. When the dishwasher fills up with water, this ‘float’ rises and as the right volume of water enters the float triggers the ‘float switch’.

This float switch then turns off the water inlet valve. The problem that could happen here is either the ‘float’ or ‘water inlet valve’ is defective and will need to be replaced.

How To Fix A Leaky Dishwasher?

Repair #1: Replacing the Gasket Seal 

When the seal on your dishwasher fails you, it is important to remember that your replacement will have to be compatible with the system that you currently have. Make sure that, when you do buy your replacement, you look at the part closely and verify that it is compatible with the dishwasher that you have. You can do this by searching for your model type and brand name.

Step 1: Begin by removing the old door seal.

  • You will need to open up the door and then pull out the current seal.
  • Pay attention which way it is currently facing so you are able to make sure that you line it up properly. Otherwise, you run the risk of installing the seal backwards, which could make the problem worse.

Step 2: Next, do a thorough job cleaning out the channel for the door seal.

  • If you leave the grime that is currently in there, you can prevent the new seal from being able to fit properly, leading to future leaking. The best way to do this is with cotton swabs and a detergent or disinfectant.
  • When you have cleaned it out, allow it to dry completely.

Step 3: Heat up the new seal with a hair dryer.

  • Oftentimes, when they come packaged, they are creased and you want to remove those creases to ensure that you can get the right seal. Make sure that you are careful not to use high heat.

Step 4: Now, it is time to install the new door seal.

  • The best way to do so is to gently fold it in half in order to find the midpoint—do not crease it, but figure out where that middle point is.
  • Then, push that midpoint into the channel at the top of the door, slowly pushing it in without stretching it out.
  • You want to push it in as much as possible. When the seal is in, close the door and let it sit.

Repair #2: Replacing The Float System 

When the float is the problem, you will need to do a bit more work to ensure that you get everything lined up. As always, make sure that you begin with the power source turned off, and then locate the float within your device. 

Also make sure that the one that you have chosen as a replacement is one that is compatible with your current machine. This is a bit more involved, and if you do not feel comfortable with it, please call a repair person for assistance.

Step 1: Remove the cover at to reach the float assembly

  • Open the door and remove the dish-rack. Remove the cover for the float assembly if it can be removed. It is typically either snapped into place, or there are screws securing it.

Step 2: Get access to the electrical system

  • Next, you must remove the screws that close the door. You are going to remove the panel at this point in time, allowing you to have access to the electrical area in your system. 

Step 3: Identify the float and remove it

  • Look inside the dishwasher at the float plug. Pull on it and then reach underneath the dishwasher, into the area that you just exposed, and identify the nut that holds the plug in place. Use your fingers to remove the nut and then remove the float. 

Step 4: Installing the new float system

  • Take the plug gasket off of the old float and install it onto the replacement. Then, push the long stem of the plug back through the tub. 
  • You must then reattach it to the nut that held it into place, and the switch, if it was connected to that. 
  • Then, it is time to begin replacing everything else. Reattach the housing for the float assembly and then reattach the kick panel. Replace all screws and then reconnect the dishwasher to the power. Then, test to see if you have fixed the problem.
