Step 1: Assess the Situation

Check if the issue is indeed a clogged drain line. If there’s standing water in your dishwasher, it’s likely due to a clog in the drain line from the dishwasher to the sink or the garbage disposal.

Step 2: Prepare the Tools

Gather the tools and materials you’ll need for the unclogging process:

  • Screwdriver
  • Baking soda
  • Vinegar
  • Pot of boiling water

Step 3: Remove Debris

Start by locating the basket in the back of the dishwasher. This basket is usually held in place by screws. Carefully remove the screws and the basket to check for large debris that might be causing the clog.

Step 4: Baking Soda and Vinegar Solution

If there’s no visible debris, it’s time to use the powerful combination of baking soda and vinegar to break down the clog.

  • In a cup, mix baking soda with just enough water to create a pourable paste.
  • Pour the baking soda paste down the drain in your dishwasher.
  • Follow up by pouring a cup of vinegar down the drain. Watch as the vinegar reacts with the baking soda, creating a fizzing action that helps break down the clog.

Step 5: Let It Set

Allow the baking soda and vinegar mixture to work its magic for about 10 to 15 minutes. This gives it time to penetrate and dissolve the clog that’s causing the drainage issue.

Step 6: Boiling Hot Water

After the waiting period, it’s time to clear the way with hot water.

  • Boil a pot of water.
  • Carefully pour the boiling water down the drain. The heat helps to further break down any remaining debris and clear the clog.

Step 7: Check for Improvement

Check to see if the water is now draining properly. If the clog has cleared, you’re good to go! If not, don’t worry; there’s another option.

Step 8: Repeat if Necessary

For more stubborn clogs, you might need to repeat the baking soda and vinegar process. Most regular clogs should clear after the first application, but severe clogs may require one or two more attempts.

Step 9: Maintenance Tip

To prevent future clogs and maintain your dishwasher’s efficiency, periodically clean the filters and components. This simple maintenance can save you from future headaches.
