How Do You Unclog A Dishwasher Drain Hose?

According to American Home Shield, there are circumstances where contacting a professional plumber for dishwasher or kitchen plumbing issues is necessary to replace motor components or wiring issues.

Here are a few simple ways to unclog your dishwasher's drain hose that doesn't require professional training or tools.

7 Ways To Unclog A Dishwasher Drain Hose

  1. Run the garbage disposal for 30 seconds to clear minor clogs in the disposal unit or release an air gap to the connecting hose.
  2. Inspect the bottom of your dishwasher for any clogs or pieces of debris that could block the filter.
  3. Change or clean the filter if your filter is filled with food debris. This will cause a failure to drain because the food is blocking the water from flushing out of the appliance. Empty or replace the filter. If you are unsure how to accomplish this task, refer to your owner's manual.
  4. Inspect the drain hose that connects the sink to the garbage disposal. Check for bends or kinks in the hose, and straighten the hose to facilitate draining correctly.
  5. Inspect the drain valve located at the valve bracket; these brackets are often found at the bottom of the dishwasher. Gently push the valve to ensure that it is flexible. If the valve is unmoveable, it is clogged.
  6. Mix one cup of baking soda and one cup of vinegar and pour the solution into the bottom of the dishwasher. Allow it to sit for 20 minutes. Once the water in the dishwasher starts to drain, run the rinse cycle with hot water to flush the drain hose. The combined ingredients should dissolve slight clogs and dissipate any grease plugging the draining hose.
  7. Listen to your dishwasher while it is washing, and note any strange sounds. If it is making a clicking or humming sound, the drain pump inside the dishwasher may need to be replaced.
