How to Unclog a Dishwasher with Baking Soda

If you’re experiencing a slow-draining dishwasher, or water backing up into the sink, chances are you have a clogged dishwasher. Don’t worry; you don’t need to call a plumber just yet. With some household ingredients, you can quickly and easily unclog your dishwasher. In this article, we’ll guide you through the simple process of using baking soda to unclog your dishwasher.

Understanding Dishwasher Clogs

Before we begin, it’s essential to understand what causes dishwasher clogs. The most common culprit is food particles, grease, and soap scum that accumulate over time. Dishwashers are designed to dispose of these elements, but some can get stuck in the drain or the garbage disposal. Additionally, clogs can occur due to damaged parts or improper use.

Tools You’ll Need

Before you start, gather the following materials:

  • Baking soda
  • Vinegar
  • A sponge or rag
  • A small bowl or cup
  • A toothbrush or other small cleaning brush
  • A flashlight

Step-by-Step Guide

Follow these simple steps to unclog your dishwasher using baking soda:

Step 1: Prepare the Dishwasher

Start by turning off the power supply to your dishwasher. If you’re not sure how to do this, unplug it or turn off the circuit breaker. Next, remove any dishes or debris from the bottom of the dishwasher.

Step 2: Locate the Clog

Use a flashlight to locate the clog. It’s usually located near the garbage disposal or the dishwasher’s drain. Once you’ve found the clog, use a toothbrush or small cleaning brush to remove any visible debris.

Step 3: Add Baking Soda

Take one cup of baking soda and pour it into the dishwasher’s drain. Let it sit for a few minutes to allow it to penetrate the clog.

Step 4: Add Vinegar

Next, take a cup of vinegar and pour it into the same drain. Vinegar and baking soda create a chemical reaction that helps to dissolve the clog. You should see some bubbling and fizzing.

Step 5: Let It Sit

Let the baking soda and vinegar solution sit for about 15-20 minutes. During this time, the chemical reaction will break down the clog.

Step 6: Rinse with Hot Water

After 15-20 minutes, turn on the hot water and let it run for a few minutes to flush out any remaining debris. You can also run a short cycle of the dishwasher to help flush out any remaining debris.

Step 7: Clean the Garbage Disposal

If your dishwasher is connected to a garbage disposal, clean it as well. Pour some baking soda down the disposal, followed by vinegar. Let it sit for a few minutes before flushing it with hot water.


While using baking soda and vinegar is a safe and effective way to unclog your dishwasher, there are a few precautions you should take:

  • Always turn off the power supply to your dishwasher before attempting to unclog it.
  • Don’t use chemical drain cleaners, as they can damage your dishwasher’s pipes and cause further clogs.
  • Be careful when cleaning the dishwasher’s drain, as sharp objects or debris can be hidden inside.
  • If you’re unsure about how to unclog your dishwasher, call a professional plumber.

Can I prevent dishwasher clogs?

Yes, you can prevent dishwasher clogs. The best way to do this is to ensure that all food particles are removed from dishes before they are placed in the dishwasher. This means scraping off any large pieces of food and rinsing off any smaller pieces. Additionally, it’s important to check the filter at the bottom of the dishwasher regularly and clean it if necessary. This will help keep the drain clear of debris that could cause a clog. Finally, avoid overloading your dishwasher with too many dishes or placing large items such as pots and pans in there as these can also block the drain and lead to a clog. By following these steps, you should be able to prevent most dishwasher clogs.

What if the clog is still there after using baking soda and vinegar?

If the clog is still present after using baking soda and vinegar, it may be a sign of a more serious issue. It’s possible that the clog is due to a blockage in your plumbing system, such as tree roots or a broken pipe. In this case, you should contact a professional plumber to assess the situation and determine what further steps need to be taken.

Alternatively, you could try using a plunger or an auger (a long metal cable with an auger head at one end). A plunger can help dislodge any debris that may be stuck in the pipes, while an auger can help break up blockages deeper in the system. If these methods don’t work, it’s best to contact a professional plumber for assistance.

How often should I unclog my dishwasher?

The frequency of unclogging your dishwasher depends on how often you use it. If you are using it multiple times a day, it should be unclogged every couple of weeks to ensure that food particles and dishes are not clogging up the drainage system.

If your dishwasher is being used less frequently, then unclogging can be done on a monthly basis. Make sure to check for any visible blockages in the filter and pipes before running the dishwasher.

Additionally, if you notice any strange smells coming from the dishwasher or if it is taking longer than usual for water to drain out, then it may need to be unclogged right away.

To unclog your dishwasher, start by removing any debris that may have built up in the filter and pipes. You can also run a cycle with vinegar or baking soda to help break down any residue that has collected over time.

Can I use bleach to unclog my dishwasher?

No, you should not use bleach to unclog your dishwasher. Bleach is a harsh chemical that can damage the pipes and components of your dishwasher if used in large amounts.

Additionally, it is not very effective at clearing clogs. Instead, you should try using a natural cleaner such as vinegar or baking soda to clean out any clogs in your dishwasher.

Start by pouring 1 cup of either vinegar or baking soda into the bottom of the dishwasher and running it on the hottest setting for about 10 minutes.

This will usually be enough to break up any clogs in the drain line. If this doesn’t work, you may need to contact a professional plumber to help clear out any more serious blockages.

Can I use salt instead of baking soda to unclog my dishwasher?

No, it is not recommended to use salt instead of baking soda to unclog your dishwasher. Salt is a corrosive material, and using it to unclog your dishwasher could damage the pipes and other components. Baking soda is a much better choice for this task because it is non-abrasive and won’t damage your dishwasher’s inner workings.

To unclog your dishwasher with baking soda, start by pouring 1/2 cup of baking soda into the bottom of the dishwasher. Then run a full cycle with hot water on the highest setting.

The hot water will help dissolve any debris that has built up in the pipes. If the clog persists, you can try running another cycle with 1/2 cup of white vinegar added to the bottom of the dishwasher instead of baking soda. This should help break down any remaining buildup and clear out your dishwasher.


Unclogging a dishwasher may seem like a daunting task, but with baking soda and vinegar, it’s a straightforward process that can save you time and money. Follow these steps, and your dishwasher will be running smoothly in no time.
