Introduction
Standing water in your dishwasher isn’t just annoying—it can lead to foul odors, mold growth, and even damage to your machine. Fortunately, most drain clogs are easy to fix with basic tools and a little DIY know-how. Follow these five steps to clear your clogged dishwasher drain and restore proper drainage.
Step 1: Check the Filter
Food particles often clog the filter at the bottom of the dishwasher.
-
Remove the filter (consult your manual for location) and rinse it under warm water.
-
For stubborn debris, soak it in vinegar overnight.
Step 2: Inspect the Drain Hose
A kinked or clogged drain hose prevents water from flowing out.
-
Disconnect the hose (located under the sink or behind the dishwasher) and flush it with hot water.
Step 3: Clear the Garbage Disposal Connection
If your dishwasher drains into a garbage disposal, the connection might be blocked.
-
Use a screwdriver to clean the disposal’s drain port.
Step 4: Test the Drain Pump
A broken drain pump won’t push water out.
-
Listen for a humming sound during the drain cycle. If silent, replace the dishwasher drain pump.
Step 5: Clean the Air Gap
The air gap (mounted on your sink) can trap debris.
-
Unscrew the cap and clear any blockages with a pipe cleaner.
