Whirlpool Dishwasher Leaking from the Bottom? Try These Fixes

Have you found water underneath your Whirlpool dishwasher? This can be very frustrating, especially when it starts spreading across the kitchen floor.

This problem is usually caused by a loose hose, too much detergent, or a dirty door seal. The checks below will help you trace the water without taking the whole machine apart.

I am confident that if you follow each solution, you should be able to find what is wrong or know when it is time to call a technician.

How to Fix a Whirlpool Dishwasher Leaking Underneath

If your Whirlpool dishwasher leaks from the bottom, first check the door seal, detergent, spray arms, and hoses. If they are fine, the pump or another part below the tub may need repair.

Before you begin, dry the floor and turn off the dishwasher at the breaker. Close the water valve before touching a hose or moving the machine.

Check the Door Seal

Water from the front of the door can run underneath the dishwasher, so it may look like the leak is coming from the bottom. Open the door and wipe the rubber seal with warm water.

Look for food, dried detergent, a tear, or a loose section. A damaged seal need to be replaced because it cannot hold the water inside the tub.

Use the Correct Detergent

Too much detergent can make more foam than the dishwasher can hold. The foam then comes through the bottom of the door and leaves water on the floor.

Only use detergent made for a dishwasher. If someone used regular dish soap, remove the foam and run a short rinse without detergent. This is one of the common cause of a sudden leak.

Clean the Spray Arms

A blocked spray arm may send a strong stream of water toward the door. Remove the lower rack, turn each spray arm by hand, and make sure a large plate or pan is not stopping it.

Use a toothpick to clear food from the small holes. Replace the arm if it has a crack. If the arms do not spray, read our guide about a Whirlpool dishwasher that is not spraying water.

Inspect the Water and Drain Hoses

Look below the sink where the water and drain hoses connect. Run a dry paper towel around each fitting. Even a slow drip will leave the towel wet.

Tighten a loose clamp after the water is turned off. Replace any hose that is cracked or swollen. If water also stays inside the tub, see how to fix water under the Whirlpool dishwasher filter. If both hoses is dry, ask a technician to check below the tub.

Have the Pump Area Checked

If the door and hoses are dry, the leak may come from the pump seal, an inlet part, or a hose below the tub. These parts are close to electrical wires and are not safe to inspect while the dishwasher is connected.

Leave the breaker and water valve off, then ask a technician to check underneath. There is few repairs you should try in this area without the correct tools.

Conclusion

Most Whirlpool dishwasher leaks can be found by checking the easy places first. Try these five solutions:

• Clean and inspect the door seal
• Use the correct dishwasher detergent
• Clean and inspect the spray arms
• Check the water and drain hoses
• Have the pump area checked

If water keeps coming back, do not run another cycle. Keep the power and water off until the leaking part is repaired.
