#### Understanding the Problem
Standing water in a dishwasher typically means something is obstructing the drainage system. According to Whirlpool, a leading appliance manufacturer, “If your dishwasher won’t drain, it may be due to a clog in the filter, drain hose, or air gap—or it could signal a pump issue.” Before diving into repairs, it’s worth identifying the root cause to avoid unnecessary work. Common culprits include food debris, grease buildup, or even a kinked hose.
Let’s break this down into actionable steps, drawing from expert advice and real-world solutions.

#### Step-by-Step Guide to Unclogging Your Dishwasher
##### Step 1: Safety First—Turn Off Power and Water
Before you start, ensure your safety. Unplug the dishwasher from the electrical outlet or switch off the circuit breaker. If possible, turn off the water supply line under the sink to prevent leaks. As Bob Vila’s team advises, “Always disconnect power to avoid electrical hazards when working on appliances” [(( Bob Vila ))].
##### Step 2: Remove Standing Water
You’ll need to manually remove the water to access the dishwasher’s interior. Grab a bucket, some towels, and a sponge or cup. Scoop out as much water as you can from the bottom of the dishwasher. This step is messy but essential for troubleshooting. Pro tip: Place towels around the base to catch spills.
##### Step 3: Clean the Dishwasher Filter
Most modern dishwashers have a removable filter at the bottom. Food scraps and debris often clog this component. According to Maytag’s official guide, “Twist the filter counterclockwise to remove it, then rinse it under warm water to dislodge grease and particles.” Use a soft brush (like an old toothbrush) to scrub away stubborn buildup, then reinstall the filter securely.
##### Step 4: Check the Drain Hose
The drain hose connects your dishwasher to the sink’s plumbing or garbage disposal. A kink or blockage here could be the issue. Locate the hose (usually under the sink), detach it carefully, and inspect it. HGTV suggests, “Run water through the hose into a bucket—if it doesn’t flow freely, use a plumber’s snake or a long brush to clear it” [(( HGTV ))]. Reattach the hose once cleared.
##### Step 5: Inspect the Air Gap (If Applicable)
If your dishwasher connects to an air gap (a small cylinder near the sink), it might be clogged with gunk. Remove the cap, clean out any debris with a pipe cleaner or toothbrush, and rinse it thoroughly. This step ensures proper drainage airflow.
##### Step 6: Test the Drain Pump
The pump expels water from the dishwasher. If it’s blocked or faulty, water won’t drain. Remove the bottom rack and check the pump area (consult your manual for its exact location). Clear any debris like glass shards or bones. If the pump still doesn’t work, it may need professional repair or replacement.
##### Step 7: Run a Vinegar and Baking Soda Cycle
Once the obvious clogs are cleared, run a cleaning cycle to flush out lingering residue. Place a cup of white vinegar on the top rack and run a hot water cycle. Afterward, sprinkle a half-cup of baking soda in the bottom and run a short cycle. This natural method, recommended by The Spruce, helps break down grease and odors [(( The Spruce ))].
##### Step 8: Test the Dishwasher
Reconnect power, turn on the water supply, and run a short cycle with a few dishes. Check for leaks or pooling water. If the problem persists, it might be time to call a technician.

#### Additional Tips for Prevention
Keeping your dishwasher clog-free requires a little maintenance. Here are some expert-backed suggestions:
– **Scrape Plates Before Loading**: Remove large food chunks to reduce debris in the filter.
– **Run Regular Cleaning Cycles**: Use dishwasher cleaner or vinegar monthly to prevent buildup.
– **Check Hoses Periodically**: Look for kinks or wear every few months.
– **Avoid Overloading**: Overcrowding can trap food and block water flow.

#### When to Call a Professional
If you’ve tried everything and water still won’t drain, the issue might involve electrical components or a broken pump. Sears Home Services notes, “A malfunctioning pump or control board often requires specialized tools and expertise.” Don’t hesitate to seek help if you’re unsure—better safe than sorry.
