How to Clean a Dishwasher Drain: A Comprehensive Guide

What is a Dishwasher Drain and Why Should I Clean It?

The dishwasher drain is a crucial component that allows water and food particles to exit the appliance. When the drain becomes clogged, it can lead to unpleasant odors, poor drainage, and even damage to the dishwasher. Cleaning the dishwasher drain regularly is essential for maintaining the appliance’s efficiency and lifespan.

Causes of Dishwasher Drain Clogs

Dishwasher drain clogs can be caused by various factors, including:

  • Food particles: Scraps of food that are not properly removed from dishes before loading them into the dishwasher can accumulate in the drain and eventually form a clog.
  • Sludge buildup: Food residue, grease, and other substances can gradually accumulate in the drain, forming a sludge that can restrict water flow.
  • Paper labels: Adhesive paper labels from food containers can stick to the dishwasher filter or drain and cause a blockage.

How Often Should I Clean My Dishwasher Drain?

Regular cleaning of the dishwasher drain is key to preventing clogs. It is recommended to clean the drain at least once a month. If you notice any signs of a clogged drain, such as slow drainage or unpleasant odors, cleaning should be done immediately.

Materials You’ll Need

Before you start cleaning the dishwasher drain, gather the following materials:

Equipment / Tools:

  • Small bowl
  • Sink or dishpan
  • Soft-bristled scrub brush
  • Drain auger/snake
  • Screwdriver (optional)

Materials:

  • Baking soda
  • Distilled white vinegar
  • Dishwashing liquid

Step-by-Step Instructions

1. Empty the Dishwasher

Begin by emptying the dishwasher and removing the lower rack.

2. Turn Off the Electricity

For safety, turn off the circuit breaker or unplug the dishwasher before cleaning the drain.

3. Locate and Remove the Dishwasher Filter

The dishwasher filter is typically located on the floor of the dishwasher. It may be a round, twist-lock filter or a cylindrical filter with a secondary flat filter beneath it. Refer to your dishwasher manual or the manufacturer’s website for specific instructions on locating and removing the filter.

4. Clean the Filter

Soak the filter in a solution of hot water and dishwashing liquid for a few minutes to loosen debris. Use a sponge or soft-bristled brush to scrub away any remaining food particles or paper labels. Rinse the filter thoroughly with hot water and allow it to air-dry.

5. Remove Clogs From the Dishwasher Drain

If you suspect a large clog in the drain, use a drain snake or auger to clear the blockage. Consult your dishwasher manual for instructions on how to locate the drain hose and disconnect it to remove the clog.

6. Clean and Freshen the Drain

To remove odors and small debris from the dishwasher drain, follow these steps:

  • Pour 1/4 cup of baking soda into the drain.
  • Follow with 1/2 cup of distilled white vinegar. The reaction between these substances will help loosen debris.
  • Allow the mixture to sit for 10-15 minutes.
  • Reassemble the filter and any screens over the drain.

7. Run a Cleaning Cycle

Once the filter is reinstalled, turn on the dishwasher and place a bowl with 1 cup of distilled white vinegar on the top dish rack. Run a regular wash cycle without detergent and skip the drying cycle. Once the cycle is complete, sprinkle 1 cup of baking soda onto the damp floor of the dishwasher and run a hot water rinse cycle. Allow the dishwasher to air-dry.

How to Prevent a Clogged Dishwasher Drain

To keep your dishwasher drain clog-free, follow these tips:

  • Scrape food particles from dishes before loading them into the dishwasher.
  • Clean the dishwasher drain monthly.
  • Ensure the water temperature is set high enough to properly clean and sanitize dishes and the dishwasher itself.

When to Call a Professional

If your dishwasher is still not draining properly after following these steps, contact a licensed plumber for assistance.
