There are lots of homeowners who cannot imagine their house is remaining functional if their dishwashers were not functioning properly. As a result, it can be incredibly frustrating if you realize your dishwasher starts to leak. This can lead to a significant amount of water damage and might lead to a major repair bill. 

Some of the most common reasons why your dishwasher might be leaking have to do with the door seal, the spray arm, and the float switch. No matter what the issue is, you need to quickly diagnose the problem before you decide if you have to repair or replace the part. In some situations, it might be better to replace the entire dishwasher.

So, how do you know if you need to replace one of the broken parts in your dishwasher? How can you fix a leak that might be present? 

We have done an extensive amount of research, compiling it into a helpful article for you. Learn from our experiences below, and figure out how you can stop your dishwasher from leaking. This could help you prevent a significant repair bill down the road. 

1. The Door Gasket of Your Dishwasher Is Not Creating a Watertight Seal

One of the first reasons why your dishwasher may be leaking at that there is up to work ask if that is not creating a watertight seal. In simple terms, your dishwasher is going to be spraying water throughout the inside of the compartment. In order to make sure this water stays on your dishes and not all over the floor kitchen, there is a door gasket that is responsible for creating a seal between the dishwasher and the door.

If the rubber seal around the exterior of your dishwasher door begins to fail, this can lead to a leak. When it is first installed, the rubber material tends to work well. Over time, this rubber material can dry out, leaving it prone to cracking. 

Furthermore, there may be food that got stuck in between the door and a seal. When this happens, the door is not able to close completely. This could cause water to leak around the seal all over your kitchen floor. 

To check and see if there is a problem with the door gasket, open the door and run your hand around the edge of the seal. See if there is anything that feels off. You should be looking for cracks while also feeling for food debris could be stuck in the seal. Make sure the door gasket is not missing any parts. 

If There Is a Problem, Replace the Gasket

If you find that there is a problem with the door seal, the solution is to replace the gasket. You can swap it out yourself, but you need to take a look at the manual to figure out what model is right for your dishwasher. That way, you know you end up with the best possible part.

When you are ready to replace the door gasket, you should feel it away from the door. Clean the channel of the gasket with warm water. You should use soap to remove any debris that might be present. 

Make sure the new door gasket is warm when you put it in place. The goal is to make sure the door gasket molds to meet the shape of your dishwasher door. Finally, make sure you press the gasket evenly on both sides. When you close the dishwasher door, make sure it seals appropriately. This will prevent the leak from coming back. 

2. The Spray Arm of Your Dishwasher Is Malfunctioning

Another possible reason why your dishwasher might have a leak is that something is wrong with the spray arm. The spray arm is responsible for rotating inside your dishwasher, cleaning the dishes. This is how it makes sure that all of your dishes are cleaned properly. If the dishwasher spray arm is malfunctioning, this could lead to a leak. 

For example, the dishwasher may be overloaded. Or, it may not have been loaded properly. If this happens, that spray arm might not be allowed to rotate. Or, the spray arm could even come dislodged from the rest of the rack. As a result, the water starts to go everywhere. 

There are also situations where the spray arm simply breaks down due to years of use. Like other parts, the spray arm is eventually going to degrade. When this happens, it is no longer going to work properly. This could cause a leak to develop in your dishwasher. 

When you take a look at the interior of your dishwasher, look closely at the spray arm. Open the dishwasher door, remove the dish rack, and spin the spray arm to make sure it is moving appropriately. 

If you find that the arm is not rotating evenly, then you should take a look at the utensils and make sure they are not in the way. If there is something blocking the spray arm, you need to remove it. You should also take a look at the arm and make sure it is not clogged due to residue buildup. You may need to clean it from time to time to make sure it works appropriately.

Oftentimes, when the spray arms in a dishwasher begin to malfunction, it is due to them simply being worn out and needing replacement.

Remove Obstacles, Clean the Spray Arm, or Install a New One

If you have found that there is something wrong with the spray arm, there are several solutions available. First, you should remove any obstructions that are in place. For example, there may be pots, pans, or utensils that are on the way. Make sure you remove these first.

Next, you should take a look at the spray arm itself. If you find that it is dirty, make sure you clean it. If there is something sticking in the way, try to remove it with a strong cleaning solution.

If you have done all of this and the spray arm is still not working properly, you need to order a new model. Take a look at the manual and see what type of spray arm you require.

When the new option arrives, unscrew the spray arm and remove it from the dishwasher. Then, take the new arm and align it with the central hub. Screw the arm in place, and make sure it can spin freely. That way, you make sure it is working properly. 

3. You Have a Drain Hose That Is Damaged

Another reason why your dishwasher might be leaking is that there is a problem with the drain hose. There is a drain hose that is responsible for supplying water to the dishwasher from the drain pump. If you remove the kick plate at the bottom of your appliance, you should be able to see this hose.

Eventually, the connections may come loose. Or, the hose itself could crack. When this happens, the dishwasher may lose water because it connects to the hose. If you see water all over the floor, there could be an issue with the hose that connects to your dishwasher. 

You should take a look at the hose from top to bottom. You may want to squirt some water through it to see if there is a leak present. If there is a leak, there are several options available.

Tighten the Fittings or Replace the Hose

To deal with this problem, you have two choices. When the wash cycle is over, remove power from the appliance. Then, place a pan underneath the dishwasher. Pinch the hose clamp tightly and make sure the fittings are tight. Then, consider running another cycle. See if there is still a leak present. 

If there is still a leak present, you need to replace the hose. Take a look at the manual and see what type of hose is recommended. Then, when the new hose arrives, you can swap out the old one for the new one. If you are not comfortable with this process, you should reach out to a professional who can help you. 

4. There Is an Inlet Water Valve That Is Not Functioning Properly

You should also take a closer look at the inlet water valve of your dishwasher. This is located at the bottom of the appliance. It allows water to flow into the dishwasher tub during the cycle. If this part is not opening and closing properly, it is possible your appliance may overflow. As a result, the excess water could end up all over the floor.

To test this problem, you should start a wash cycle. Then, in the middle of the cycle, open the door. If water continues to fill in the dishwasher even when the door is open, then there is probably an issue with the inlet water valve. You need to fix this problem quickly because you could end up with a serious leak all over your kitchen floor.

Replace the Inlet Water Valve

The only way to deal with this problem is to replace the inlet water valve. It is impossible to repair a damaged piece, so you need to order a new one and follow the instructions from the manufacturer. 

There are a lot of steps involved in this process. You need to remove the kick plate panel, remove the hose and screws, and remove the clamp that is connected to the water inlet valve. Then, you will need to disconnect the wires before you install the replacement part.

Clearly, this is a lot of work, so you may want to reach out to a professional who is familiar with the wiring of a dishwasher. 

5. The Float Switch Is Not Working Properly

Finally, there could also be a problem with the float switch. Your float assembly includes a float and a float switch. All of this is required to make sure your dishwasher maintains an appropriate water level. When your dishwasher runs, the float lifts as the water level rises.

When the dishwasher reaches a certain water level, there is a float switch that is responsible for turning off the water. If there is something wrong with a switch, then the water may never shut off. As a result, the dishwasher overflows, leading to a leak. 

To figure out if this is the problem, you should open the door in the middle of the cycle. Take a look at the heating element and compare this to the water level. If the water level is above the heating element, then this is a sign something might be wrong with the float switch.

If you cannot get the door open in the middle of a wash cycle, you can also test the float switch using a multimeter. Make sure there is no electricity flowing through the float switch. If there is not, it is time to replace it.

Replace a Faulty Float Switch

This is another job that you might be able to do on your own. If you need a new float switch, you should take a look at the manual to figure out what you need. Then, you should order a new one. 

Even though this is something you might be able to do on your own, you may also be better off working with a professional in this situation. If you start messing with the internal components of the electrical wiring of your dishwasher, you could risk voiding your warranty. Furthermore, this could be a serious safety issue. If you are not comfortable with this, you should reach out to a professional who can help you.
