Whirlpool Dishwasher Leaking: 6 Easy Ways To Fix It Now

Whirlpool is a well-known and reputable brand that has been producing appliances for years and years. The company is known for its high-quality dishwashers that are efficient and reliable; however, even the best appliances might malfunction from time to time, and one of the most common issues with Whirlpool is dishwasher leaks.

If you notice water leaking from your Whirlpool dishwasher, it is essential to address the problem promptly. Ignoring the issue can lead to more significant problems and costly repairs.

Fortunately, though, the problem is typically quick and easy to fix if you know exactly what to look for. In this article, we’ll examine why your Whirlpool dishwasher may be leaking and the steps that can be taken to fix it.

Why is your Whirlpool Dishwasher Leaking?

There are a few different possible causes your Whirlpool dishwasher may be leaking. Understanding the cause of the problem is essential to find the right solution.

Here’s a quick list of the most common culprits for your leaky dishwasher:

1. Too Much or Wrong Type of Detergent

Using excessive amounts of detergent (or even the wrong type of detergent) can cause your Whirlpool dishwasher to leak. Excess dishwasher detergent can create a buildup of suds, which can overflow from the appliance, causing water to leak.

The wrong detergent can also cause problems, especially if not designed for dishwasher use.

2. Overloaded Dishwasher

Overloading your Whirlpool dishwasher can cause it to leak too. The appliance is only designed to hold and clean a specific number of dishes of a certain size and weight, and exceeding this capacity could force water out of the unit.

It’s vital that you follow the recommendations found in your user’s manual when loading your dishwasher to avoid leaking and other problems.

3. Dishwasher is Not Level

A Whirlpool dishwasher that is not level could also cause water to leak. The feet might be unevenly raised, or the appliance might be placed on an uneven surface, which might cause it to wobble or shake.

If the appliance is not level, it can cause water to accumulate in one corner of the device, leading to leakage.

4. Faulty Water Inlet Valve

You might also have an issue with one of the parts in your appliance. The first part that might be the culprit is the water inlet valve on your machine.

The water inlet valve is necessary to regulate and monitor the water flow into the dishwasher. If the valve becomes damaged or is faulty, this could cause water to leak from the appliance.

5. Loose Pump Seal

Another component you might have to monitor closely is the pump seal. The pump seal is responsible for keeping water inside the appliance, and a properly tight seal will prevent anything from leaking from the dishwasher’s pump housing.

If the seal is loose or damaged, water can escape and leak out while the machine is running and water is flowing through it.

6. Damaged Door Latch

The door latch on a Whirlpool dishwasher is designed to keep the door securely closed and sealed during the wash and rinse cycle. If the latch is damaged or worn, water leaks out while the machine runs.

7. Faulty Spray Arm

Finally, you might be dealing with an issue with the spray arm. The spray arm on a Whirlpool dishwasher is a necessary component to spray water on the dishes during the washing cycle.

It’s located at the top of the inside of your dishwasher tub and is intended to spin during a cycle. If the spray arm is damaged or faulty, it can create a leaking issue.

How to Fix a Leaking Whirlpool Dishwasher

Now that you understand some of the common reasons your Whirlpool dishwasher may be leaking, here are some simple solutions you can try out to fix the problem:

1. Manage the Load Size

The size of your dishwasher’s load can significantly impact its ability to prevent leaks. As we already know, overloading your appliance can cause water to overflow and leak from the machine.

Additionally, using too much or the wrong detergent can lead to excess water and leakage. To prevent this issue, ensure you use the appropriate amount of detergent for your load size and avoid overloading the dishwasher.

You can consult your user manual to confirm that you follow the proper instructions since this can vary between different models.

2. Level Your Appliance

As we’ve noted, an unlevelled dishwasher can cause water to accumulate in one corner of the machine, leading to leakage.

To level your appliance, you will need to use a spirit level. Place the tool on the dishwasher door and adjust the feet of the appliance until it is level. To avoid accidents, it is crucial to ensure the dishwasher is securely in place before testing it.

3. Check the Water Inlet Valve

If none of these solve your problem, you will need to check out some of the parts of your appliance, starting with the water inlet valve, which is responsible for regulating the water flow into the dishwasher.

To check the valve, first turn off the appliance and unplug it from the power outlet, allowing the power to drain from the machine, and shut off the water supply valve too.

Next, you’ll need to disconnect the water supply line from the valve and inspect it for any signs of damage or debris. If you notice any issues, thoroughly clean the valve and replace it if necessary. You might need to contact a professional.

4. Check the Pump Seal

The next step is to assess the pump seal. This seal prevents water from leaking from the dishwasher’s pump housing.

If the seal is damaged or worn, water can leak out of the machine. Remove the lower spray arm and the pump housing cover to check the pump seal.

Investigate the seal thoroughly, looking for any signs of damage or wear and tear. It’s important to ensure the seal is correctly installed and secure before reassembling the dishwasher.

5. Check the Door Latch

Next, check the door of your appliance. The door latch and hinges on your Whirlpool dishwasher are designed to keep the door securely closed during the washing cycle.

To check the door latch, thoroughly inspect it for any signs of damage, and replace it if necessary. Ensure that the latch is correctly aligned and secure before testing the dishwasher.

You can also check the hinges and the rubber seals around the dishwasher door. If you notice any issues with these parts, then you might need to replace them.

6. Check the Spray Arm

Finally, the spray arm on your Whirlpool dishwasher is responsible for spraying water on the dishes during the washing cycle. If the spray arm is damaged or faulty, it could cause a leak from the appliance.

Check on the inside to see whether the spray arm is aligned correctly and spins easily when you turn it; make sure that it’s not loose or worn and that there’s no other damage. If you notice an issue, it might need to be looked at by an appliance professional.

Final Thoughts

In conclusion, a leaking Whirlpool dishwasher can be a frustrating problem. Fortunately, by understanding the common reasons why your appliance may be leaking and following the steps outlined in this article, you can fix the problem quickly and easily.

If you cannot fix the problem on your own or notice significant damage to your appliance, it is crucial to seek professional help to prevent further damage and ensure that your dishwasher continues to work correctly.

Remember to always follow the manufacturer’s instructions and safety precautions when working with appliances.
