Why is My Dishwasher Not Draining?

Dishwasher Not Draining? Here’s What to Do

If you open your dishwasher and see standing water, don’t panic. Many common causes of drainage problems are easy to troubleshoot. Here’s what to check before calling a technician.

Quick Checks First

  • Cycle interrupted?
    • A power surge, door opened mid-cycle, or accidental button press could stop the dishwasher before draining. Try restarting with a quick cycle.
  • Connected to a garbage disposal?
    • Run the disposal with water to clear any clogs.
  • Sink draining slowly?
    • Try a mix of baking soda and vinegar, followed by hot water. Use a plunger if needed.

If those steps don’t fix the issue, disconnect power and check the components below.

Inspect the Filter

  • Remove the filter and clean out food scraps, labels, or debris.
  • Rinse thoroughly and reinstall.

Check the Drain Hose

  • Look for kinks, crushing, or buildup.
  • Disconnect the hose and flush it clean.
  • Blow through it to check for clogs.
  • Clean the connection point at the sink or disposal too.

Check the Drain Valve

  • Find the drain valve near the bottom of the dishwasher.
  • Wiggle the valve or press it to make sure it’s not stuck.
  • Remove any visible debris.

Inspect the Pump

  • Look for broken glass or debris inside the pump.
  • Make sure the impellers spin freely.
  • Strange noises during a cycle may point to a failing motor or pump.

Final Steps

After checking everything:

  • Reconnect all hoses.
  • Run a short cycle.
  • Listen for proper draining.
