Dishwasher Not Draining? Here’s What May Be Wrong

A dishwasher that leaves water in the bottom after the cycle is one of the most common kitchen appliance problems homeowners run into.

Typical causes include:

  • clogged filter or sump area
  • blocked drain hose
  • bad drain pump
  • air gap obstruction if one is installed
  • disposal knockout plug not removed after installation
  • electrical or control issue preventing full drain operation

    • A few things you can check safely:

  • clean the dishwasher filter thoroughly
  • inspect the bottom for food debris or broken glass
  • run the garbage disposal before starting a cycle if they share a drain path
  • check whether the unit drains during cancel or reset mode

    • If the dishwasher smells bad, leaves standing water, or starts cleaning poorly at the same time, there may be more than one issue at play.
