Dishwasher Not Draining Water

Dishwasher Not Draining: Causes and Solutions

Standing water in your dishwasher after a cycle indicates a drainage problem that should be addressed promptly to prevent odors and potential damage.

Check These First

1. Filter and Drain Area

Most drainage issues stem from debris in the filter and drain area:

• Remove and clean the filter (consult your manual for location)
• Check the drain area for food debris, broken glass, or foreign objects
• Inspect the drain cover for blockages

2. Garbage Disposal Connection

If your dishwasher drains through the garbage disposal:

• Run the disposal to clear any blockages
• Check if the knockout plug was removed during installation (new disposals)
• Inspect the connection for clogs

3. Drain Hose

The drain hose can become kinked, clogged, or improperly positioned:

• Check for kinks in the hose
• Verify the high loop installation (prevents backflow)
• Look for clogs by disconnecting and flushing with water

Possible Component Failures

• Drain pump: May be clogged or failed
• Check valve: Stuck closed preventing drainage
• Control board: Not sending drain signal

Temporary Solution

If you need to use the dishwasher before repairs:

1. Remove standing water with towels or wet vacuum
2. Clean the filter thoroughly
3. Run a short cycle to test
