How to Unblock a Dishwasher Drain

Modern Stainless Steel Dishwasher

Dishwashers were created to make our lives easier, so it can be stressful and frustrating when your dishwasher is no longer running as it should. At Sydney Emergency Plumbing, we’ll tell you how to unblock your dishwasher drain so it can be fixed in time for dinner, and you don’t have to wash your dishes by hand.

Signs That Your Dishwasher Isn’t Working Properly

How do you know if there is something wrong with your dishwasher?

  • If it’s making weird noises like gurgling
  • If it’s not cleaning your dishes properly
  • If it’s vibrating or thumping
  • If water is backing up in your sink
  • If it retains water after each cycle

How Do You Unblock a Dishwasher Drain

  • Make sure the problem is a blocked drain
    Before trying to fix your dishwasher, make sure the problem is a blocked drain. Some common signs include water all over the floor, an error message on your dishwasher or dirty dishes after a cycle.
  • Remove all your dishes and the dishwasher racks
    Run water through your kitchen sink and dishwasher.
  • Disconnect your dishwasher
    Make sure to disconnect your dishwasher from the power. Safety first!
  • Gather your tools
    Get all the tools and equipment you’ll need to fix the dishwasher. This includes a bucket, a screwdriver (to take the drain grate off), a drain snake or auger, baking soda and vinegar.
  • Dry the dishwasher
    Use a towel to mop any remaining water in the dishwasher and the floor.
  • Clean the dishwasher drain
    Clean the dishwasher drain using a natural solution of equal parts vinegar and baking soda. Pour the liquid at the bottom of the dishwasher and let it sit for about 15 minutes before running a rinse cycle on the highest setting.
  • Check your drain hose
    Pull the dishwasher away from the wall to access the dishwasher drain hose. Inspect the hose for any damage and then check for a blockage. Use pliers or a similar tool to loosen the clamp and hose and check for a clog.

One way to test for a clog is to run hot water through the hose and see how the water flows. If the hose is blocked, use a drain cleaner and follow the instructions to flush the debris out. If your hose is too clogged, replace it with a new one.

How to Prevent a Blocked Dishwasher Drain

Here are some ways to prevent a blocked dishwasher drain:

  • Rinse your dishes: Rinse your dishes to remove larger pieces of food before placing them into the dishwasher.
  • Check the dishwasher: Check the dishwasher and its components to see that everything works properly. If you see a debris buildup, clean it before running another cycle.
  • Clean your dishwasher: Clean your dishwasher at least once a month, including the filter.
  • Hot water cycle: Regularly using a hot water cycle will help to move any debris buildup.
  • Run the dishwasher often: If the dishwasher is not used for a while, it will not work as well. Make sure you run the dishwasher at least once a week to ensure that it keeps running smoothly.

If you still can’t get your dishwasher to run, it may be time to call a professional blocked drain plumber, who will have it up and running again in no time.
