Step-by-Step Guide: How to Fix a Dishwasher That Won’t Drain

Step 1: Check for Blockages

The first step in fixing a dishwasher that won’t drain is to check for blockages in the drain hose, pump, or filter. Start by inspecting the drain hose for any kinks, twists, or clogs that may be obstructing the flow of water. Remove the drain hose from the dishwasher and the sink drain and use a flashlight to look for any debris or buildup inside the hose. Clear any blockages using a pipe cleaner or a straightened coat hanger.

Step 2: Inspect the Drain Pump

Next, inspect the drain pump for any obstructions that may be preventing it from draining properly. The drain pump is typically located at the bottom of the dishwasher and may be accessed by removing the lower front panel or the kick plate. Use a screwdriver to remove the screws holding the panel in place and carefully lift it off to expose the drain pump. Check for any debris or foreign objects, such as food particles or broken glass, and remove them using needle-nose pliers or tweezers.

Step 3: Clean the Filter

Many dishwashers are equipped with a filter or screen that traps food particles and debris to prevent them from clogging the drain pump. Remove the lower rack from the dishwasher and locate the filter or screen at the bottom of the tub. If the filter is removable, take it out and rinse it under running water to remove any accumulated debris. Use a soft brush or sponge to scrub away stubborn buildup, then reinstall the filter in the dishwasher.

Step 4: Check the Air Gap

The air gap is a small device located on the countertop or sink near the dishwasher that prevents dirty water from backing up into the dishwasher. If the air gap becomes clogged or blocked, it can cause the dishwasher to not drain properly. Remove the cover of the air gap and check for any debris or buildup inside. Use a pipe cleaner or small brush to clean out the air gap and ensure that it is functioning properly.

Step 5: Run a Drain Cycle

Once you have checked for and cleared any blockages in the drain hose, pump, filter, and air gap, run a drain cycle to test the dishwasher’s drainage. Place a container or towel on the floor beneath the dishwasher to catch any water that may leak out during the cycle. Start the dishwasher on a drain cycle or a short wash cycle with no dishes inside and monitor the drain to ensure that water is flowing freely and draining properly.

Step 6: Check the Garbage Disposal

If your dishwasher is connected to a garbage disposal, check to see if the disposal is clogged or blocked. Run the disposal to ensure that it is functioning properly, and use a flashlight to inspect the drain opening for any obstructions. Clear any blockages using a plunger or a plumbing snake, then run the dishwasher again to see if the drainage problem has been resolved.

Step 7: Inspect the Drain Valve

If the dishwasher still won’t drain after checking for blockages and cleaning the filter, pump, and air gap, the drain valve may be malfunctioning. The drain valve is a solenoid-operated device that opens and closes to allow water to flow out of the dishwasher. Use a multimeter to test the continuity of the drain valve and determine if it is working properly. If the drain valve is defective, it will need to be replaced to restore proper drainage.

Step 8: Call a Professional

If you’ve tried all of the above steps and your dishwasher still won’t drain, it may be time to call a professional plumber for assistance. A plumber can conduct a thorough inspection of your dishwasher and plumbing system to diagnose the underlying issue and recommend appropriate solutions. They have the expertise and specialized tools needed to identify and resolve complex drainage problems and ensure that your dishwasher is functioning properly.

Tips for Success:

• Regularly inspect and clean your dishwasher’s filter, pump, and air gap to prevent blockages and ensure proper drainage.


• Run hot water through the sink before starting the dishwasher to help dissolve grease and food particles and improve drainage.


• Use a dishwasher cleaner or descaler periodically to remove built-up soap scum and mineral deposits that may be affecting the dishwasher’s performance.


• Avoid putting large food scraps or hard objects, such as bones or fruit pits, into the dishwasher to prevent clogs and damage to the drain pump.


• Check the owner’s manual for your dishwasher for specific maintenance tips and troubleshooting advice.

By following these steps and tips, homeowners can effectively fix a dishwasher that won’t drain and restore its functionality without the need for professional help.
