Safety Precautions

Safety first! Before you start working on your dishwasher, ensure your safety by following these precautions:

  • Disconnect the dishwasher from the power source.
  • Put on protective gloves and safety goggles.
  • Work in a well-ventilated area.

Tools and Materials You’ll Need

Gather the following tools and materials before you begin:

  • Screwdriver
  • Baking soda
  • Vinegar
  • Soft-bristle brush
  • Towel

Step 1: Prepare Your Dishwasher

Start by emptying the dishwasher and removing any dishes, utensils, or debris from the bottom.

Step 2: Remove Dish Rack and Filter

Carefully take out the dish rack and filter from the dishwasher. These components are usually removable and may require unscrewing.

Step 3: Inspect and Remove Debris

Inspect the filter and the area beneath it for debris, food particles, and foreign objects. Use a soft-bristle brush to gently remove any obstructions.

Step 4: Create the Baking Soda and Vinegar Solution

Mix a cup of baking soda with a cup of vinegar to create a fizzy solution. Be prepared for some bubbling when these two ingredients combine.

Step 5: Pour the Solution

Carefully pour the baking soda and vinegar solution into the bottom of the dishwasher. Make sure to cover any visible clogs.

Step 6: Wait and Let It Work

Close the dishwasher door and let the solution sit for about 15-20 minutes. During this time, the mixture will work its magic, breaking down the clogs.

Step 7: Run a Rinse Cycle

After waiting, run a rinse cycle to flush out the loosened debris. Use hot water for the best results.

Step 8: Reassemble and Test

Reassemble the dish rack and filter, ensuring everything is securely in place. Plug the dishwasher back in, and run a full cycle with a load of dishes to confirm that the clog is gone.
