Tips on How To Clean Dishwasher Drain Properly

There are various ways to clean your dishwasher drain. We have outlined the most effective steps below:

  • Preparation: Before starting any maintenance, ensure to unplug or turn off your dishwasher. This is a necessary safety precaution to prevent electrical shocks when cleaning.
  • Remove Debris: First, remove any large objects like foods, utensils, and other debris blocking your dishwasher’s drain. Use a pair of tongs to pull out and discard these items carefully.
  • Locate and Remove the Dishwasher Filter: Next, locate and remove the drain filter. Over time, food debris can collect in your dishwasher’s filter, so it’s essential to clean it regularly. Pour hot water for about 15 minutes, then rinse and reinstall.
  • Pour Boiling Water: This is an excellent way to unclog your dishwasher and help break up any built-up grease that causes a clogged dishwasher drain. Fill a pot with boiling water and pour it over the dishwasher drain. Let it sit for 10-15 minutes before running a cycle.
  • Check the Dishwasher Drain Hose Connection: The next step is to check your dishwasher’s drain hose. Ensure no kinks or bends are blocking your dishwasher’s drainage system.
  • Use a Plunger: If all else fails, use a plunger to remove any stubborn blockages. Place the plunger over the clogged drain and plunge up and down vigorously for several minutes. This should help dislodge any stubborn debris that’s causing the blockage.
  • Vinegar and Baking Soda Solution: Baking soda and vinegar make a great homemade solution for clearing a clogged dishwasher drain. Mix 1 cup of baking soda with 1 cup of white vinegar and pour it down the drain. The reaction between these two ingredients should help break up any blockages in your dishwasher’s drainage system.

How to Clean the Garbage Disposal?

In many homes, kitchen sink drains are connected to the garbage disposal. This machine eliminates large food particles by crushing them into small pieces that can easily pass through the drain.

Most of the time, the dishwasher and garbage disposal will be connected to the same 3-way valve that leads to the sewer line.

Here is a brief explanation of deep cleaning your dishwasher drain by clearing the garbage disposal.

Step 1: Start running the garbage disposal on high speed to help break down any food scraps that may be stuck in the blades.

Step 2: Pour a cup of baking soda and white vinegar down the drain. The reaction between these two ingredients will help break up any grease or clog blocking your dishwasher’s drainage system.

Step 3: Let the mixture sit for 15 minutes, then run the garbage disposal on high speed again. This should help clear up any remaining debris.

Step 4: Finally, rinse the drain with hot water to remove any residue and clean off the blades of your garbage disposal.

How to Clean Your Dishwasher Drain to Prevent Clogs?

You can take several preventive measures to ensure your dishwasher drain stays clean and clog-free.

Step 1: Regularly remove large objects like silverware, spoons, or other items blocking the drain.

Step 2: Use a strainer to catch food particles before they get stuck in the filter.

Step 3: Run hot water for about 15 minutes after each use to help break up any food debris that might be stuck in the drain.

Step 4: Consider using a natural cleaning solution like baking soda and vinegar to deep clean your dishwasher’s drainage system quarterly. This will help keep your dishwasher running smoothly and prevent future clogs.

How to Clean Your Dishwasher Drain Hose?

The dishwasher drain hose carries wastewater from your dishwasher to the sewer line. Over time, this hose can become clogged with food debris, grease, and other residues that prevent it from draining properly. Here’s how to clean your dishwasher hose:

Step 1: Disconnect the hose.

Step 2: Clean the Hose Out. Use soapy water and a stiff brush to clean out the inside of your dishwasher drain hose thoroughly. Be sure to remove any caked-on residue or grime that could be blocking it.

Step 3: Rinse the hose with hot water and ensure it is entirely free of any soapy residue.

Step 4: Finally, reattach the dishwasher drain hose to its original attachment point and secure it tightly.

How Frequently Should You Clean Your Dishwasher Drain?

It’s recommended that you thoroughly clean your dishwasher drain every 3-6 months. This will help keep it in the best condition and ensure that it continues to work optimally.
