Check the drain hose
When your dishwasher is not draining properly, the first thing you should check is the drain hose. Inspect the hose for any kinks or bends that may be blocking the water flow. Straighten out any entanglements you find to ensure a smooth passage for the water. Additionally, make sure the hose is properly connected to both the dishwasher and the drain. Loose connections can cause leaks or disruptions in the draining process. Finally, check for any clogs or obstructions in the hose. Use a flashlight to look for debris or objects that might be blocking the water from flowing freely. If you notice any clogs, remove them carefully using gloves or a long brush.
Unclog the drain pump
The drain pump plays a crucial role in removing water from your dishwasher. If the pump is clogged, it can lead to drainage issues. Start by locating the drain pump in your dishwasher. In most models, it is found at the bottom of the unit. Once you have located it, carefully remove any debris or objects that may be blocking the pump. This can include food particles, small utensils, or even broken glass. It’s essential to exercise caution while doing this to avoid injury. After cleaning the pump, don’t forget to check and clean the pump filter as well. This filter prevents larger items from entering the pump and causing blockages.
Clear the air gap
The air gap is an important component in your dishwasher’s drainage system. It prevents dirty water from flowing back into the dishwasher and contaminating your clean dishes. To clear the air gap, start by identifying its location. It is generally a small, cylindrical device mounted on top of the sink or countertop adjacent to the dishwasher. Once you have located it, carefully remove the cap and clean the air gap. Use a brush or a toothpick to dislodge any debris that may be causing a blockage. Make sure the openings are clear and free from any obstructions. Finally, check if there are any blockages within the air gap plumbing by blowing into it gently or using a small wire to clear it.
Inspect the garbage disposal
If your dishwasher is connected to a garbage disposal, it is essential to check its functionality when troubleshooting drainage issues. Start by verifying if the garbage disposal is working properly. Run water and turn on the disposal to ensure it is not clogged or jammed. If there are any blockages, unclog them using appropriate tools or follow the disposal manufacturer’s instructions. Additionally, make sure the dishwasher drain line connected to the garbage disposal is clear. Remove any debris or clogs from the line to allow smooth water flow. Clearing any issues with the garbage disposal can often resolve drainage problems in your dishwasher.

Clean the dishwasher filter
The dishwasher filter is responsible for trapping food particles and preventing them from clogging the drainage system. Over time, the filter can become dirty and obstruct the water flow. To clean the dishwasher filter, begin by locating it. It is usually found at the bottom of the dishwasher, near the spray arms. Carefully remove the filter and rinse it under running water to remove any loose debris. Use a soft brush or a toothbrush to gently scrub away any stubborn particles. After cleaning, inspect the filter for any damage or wear. If you notice any cracks or tears, replace the filter to ensure optimal performance.
Check the drain valve
The drain valve regulates the flow of water during the draining process. If it is blocked or malfunctioning, it can hinder proper drainage in your dishwasher. Start by locating the drain valve in your dishwasher. It is usually found near the drain pump. Carefully test the valve for any blockages by blowing air into it or using a small wire to dislodge any debris. Ensure that the valve opens and closes smoothly without any obstructions. If you notice any issues or the valve is not functioning correctly, it may need to be replaced. Consult the dishwasher’s manual or contact a professional for guidance on replacing the drain valve.

Inspect the drain solenoid
The drain solenoid is responsible for opening and closing the drain valve to facilitate the drainage cycle. If the solenoid is faulty, it can cause drainage problems in your dishwasher. Begin by identifying the drain solenoid, which is typically located near the drain valve. Check if it is functioning correctly by listening for a clicking sound when the dishwasher is in the drain cycle. If there is no sound or it sounds abnormal, the solenoid may need to be replaced. Like with any electrical component, ensure that the dishwasher is disconnected from the power source before attempting any repairs or replacements. Consult a professional or the dishwasher’s manual for proper guidance.
Troubleshoot the drain pump motor
The drain pump motor is responsible for pumping out the water from your dishwasher’s tub. If it is not running, your dishwasher will not be able to drain properly. To troubleshoot the drain pump motor, first, confirm if it is running or not. Start a cycle and listen for the sound of the motor. If you do not hear any noise or the motor is not functioning, it may be the result of power supply issues. Check the power supply to the dishwasher and ensure it is connected and functioning correctly. If the power supply is not the problem, you may need to replace the drain pump motor. Contact a professional or refer to the dishwasher’s manual for guidance on replacing the motor.

Check the high loop
The high loop in your dishwasher’s drain hose prevents backflow of water from the sink into the dishwasher. If it is not properly installed or positioned, it can lead to drainage problems. Begin by inspecting the high loop. It is usually located at the underside of the sink, near the back. Check if it is correctly installed and that the hose is looped higher than the sink drain inlet. If the high loop is not properly positioned, adjust or reposition it to ensure that it functions effectively. This simple adjustment can often resolve drainage issues and keep your dishwasher running smoothly.
Call for professional assistance
If you have followed all the aforementioned troubleshooting steps and your dishwasher is still not draining properly, it may be time to seek professional assistance. Contact a dishwasher repair service in your area and explain the issue, as well as the steps you have already taken to troubleshoot the problem. A professional technician will be able to provide expert advice, further diagnosis, and recommend the best course of action. Follow their guidance or schedule a service appointment for a comprehensive inspection and necessary repairs. Remember, professional assistance can save you time, effort, and potentially prevent further damage to your dishwasher.
