How Do You Clean Washing Machine Pipes?

Published in Appliance Maintenance 3 mins read

Cleaning washing machine pipes generally involves removing clogs and buildup to ensure proper drainage and prevent odors. Here's a step-by-step guide:

  1. Prepare Your Supplies: Gather baking soda, vinegar, hot water, a funnel, a baster (or similar tool), and protective gloves.

  2. Baking Soda Treatment:

    • Use a funnel to carefully pour about 1/4 cup of baking soda directly into the washing machine drain pipe. This acts as a mild abrasive and deodorizer.
  3. Vinegar Activation:

    • Using a baster or small cup, pour approximately 1/4 cup of vinegar into the drain pipe, following the baking soda. The mixture will fizz, which helps to loosen buildup.
  4. Let it Sit: Allow the baking soda and vinegar mixture to sit for at least 30 minutes, or preferably longer (even overnight for stubborn clogs). This allows the chemical reaction to break down the blockage.

  5. Flush with Hot Water:

    • After the waiting period, carefully pour a large amount of very hot water (but not boiling, to avoid damaging plastic pipes) down the drain to flush away the loosened debris.
  6. Repeat if Necessary: If the drainage is still slow or the clog persists, repeat the entire process. Stubborn clogs might require multiple treatments.

  7. Inspect and Clean the Drain Hose: Disconnect the drain hose from the washing machine and the drainpipe. Inspect it for kinks or blockages. Flush the hose with water to remove any remaining debris. You can also use a long, flexible brush to scrub the inside of the hose.

  8. Check and Clean the Drain Opening: After disconnecting the hose, visually inspect the drain opening for lint or debris. Remove any visible blockages.

  9. Prevention: To prevent future clogs, regularly clean the lint trap in your washing machine (if it has one), avoid using excessive amounts of detergent, and occasionally run an empty washing machine cycle with hot water and a cup of vinegar.

Important Considerations:

  • Pipe Material: Ensure the hot water and cleaning solutions are compatible with your pipe material (PVC, copper, etc.) to avoid damage.
  • Safety: Wear gloves to protect your hands from chemicals and hot water.
  • Severe Clogs: If the clog is severe and these methods are ineffective, consider contacting a professional plumber.
