How to Install Dishwasher Seal

If you find leaks near your dishwasher door accompanied by water pooling on your kitchen floor, you might not need to rush to call a repair technician. Take a moment to inspect the seal yourself by opening the dishwasher door. If it’s worn out or damaged, it’s time to replace it. Installing a new dishwasher seal is a straightforward task that you can handle yourself with a bit of guidance. Here’s a step-by-step guide to help you through the process.

Step 1: Gather Your Tools and Materials

Before you begin, make sure you have all the necessary tools and materials. You will need:

  • A new dishwasher door seal (compatible with your dishwasher model)
  • Screwdrivers (Phillips and flat-head)
  • Needle-nose pliers
  • Soft cloth
  • Warm soapy water

Having everything ready will make the process smoother and quicker.

Step 2: Disconnect the Dishwasher

Safety first! Disconnect the dishwasher from the power supply to avoid any electrical hazards. Unplug it from the wall socket or switch off the circuit breaker that supplies power to the dishwasher.

Step 3: Remove the Old Seal

Open the dishwasher door fully to expose the door seal. The seal is usually located around the edge of the door. Gently pull the old seal out of its groove using your fingers or needle-nose pliers. If the seal is stuck, use a flat-head screwdriver to pry it out carefully. Be cautious not to damage the groove where the new seal will sit.

Step 4: Clean the Groove

With the old seal removed, take a soft cloth and dip it in warm soapy water. Clean the groove thoroughly to remove any debris, grime, or old adhesive. A clean groove ensures a snug fit for the new seal, preventing future leaks. Dry the groove completely with a dry cloth before proceeding.

Step 5: Install the New Seal

Take the new dishwasher seal and locate the top center of the door. Start by inserting the seal into the groove at the top center, pressing it firmly into place. Work your way around the door, pushing the seal into the groove along the sides and bottom. Make sure the seal sits evenly without any twists or gaps.

Step 6: Secure the Seal

Once the new seal is in place, close the dishwasher door and latch it shut. This will help the seal conform to the door’s shape. Leave the door closed for a few hours to allow the seal to set properly. This step is crucial for ensuring a tight, leak-free fit.

Step 7: Reconnect the Dishwasher

After the seal has set, reconnect the dishwasher to the power supply. Plug it back into the wall socket or switch the circuit breaker back on. Your dishwasher is now ready for a test run.

Step 8: Test for Leaks

Run a short cycle to test the new seal. Observe the dishwasher closely during the cycle to ensure there are no leaks around the door. If you notice any water escaping, double-check the seal’s placement and make any necessary adjustments.


Replacing a dishwasher door seal is a simple DIY task that can save you the cost of a repair technician. By following these steps, you can fix leaks and keep your kitchen floor dry.
