Let’s unravel the mystery together and ensure your dishes come out sparkling clean after every cycle.

Quick Summary
There could be several reasons why your LG dishwasher is not draining, such as a clogged filter or drain hose, a faulty drain pump, or a problem with the drain impeller. Check for any blockages in the filter and drain hose, ensure the garbage disposal is clear, and inspect the drain pump for any issues. Running a dishwasher cleaner cycle can also help remove any buildup causing drainage problems. If the issue persists, it may be best to consult a professional technician for further diagnosis and repair.

Checking The Drain Hose

A common reason for a LG dishwasher not draining properly is a clogged or improperly installed drain hose. To check the drain hose, start by turning off the dishwasher and disconnecting it from the power source. Next, locate the drain hose at the back of the dishwasher and inspect it for any twists, kinks, or clogs. Ensure the hose is not pinched or damaged in any way that could be obstructing water flow.

If the drain hose appears to be clear, detach it from the dishwasher and the sink, then run water through it to check for any blockages. Use a pipe cleaner or a small brush to gently remove any debris that could be causing the drainage issue. Additionally, ensure the drain hose is positioned correctly – it should be looped up to prevent backflow of water and should have a straight path to allow for efficient drainage. After thoroughly checking and cleaning the drain hose, reconnect it securely and test the dishwasher to see if the drainage problem has been resolved.

Inspecting The Drain Filter

To troubleshoot your LG dishwasher not draining, start by inspecting the drain filter. The drain filter is a common culprit for drainage issues as it can easily become clogged with food particles, grease, and debris. To access the drain filter, remove the bottom rack of the dishwasher and locate the filter near the bottom of the tub.

Inspect the drain filter for any blockages or buildup that may be hindering proper drainage. Clean the filter by rinsing it under running water and using a soft brush to remove any stubborn debris. Ensure the filter is securely reinstalled before running a test cycle to see if the draining issue has been resolved. Regularly cleaning the drain filter can prevent future drainage problems and keep your LG dishwasher running smoothly.

Testing The Drain Pump

To test the drain pump of your LG dishwasher, start by disconnecting the power source and accessing the drain pump. You can typically find the drain pump at the bottom of the dishwasher near the back. Check for any debris or blockages that may be preventing the pump from functioning correctly. Clear out any obstructions carefully to ensure proper drainage.

Next, you can use a multimeter to test the drain pump for continuity. Set the multimeter to the ohms setting and touch the probes to the terminals of the pump. If the multimeter displays a reading of zero ohms, it indicates that the pump has continuity and is functioning properly. However, if there is no continuity, it may be a sign that the drain pump needs to be replaced.

After testing the drain pump for continuity, visually inspect the pump for any signs of damage or wear. Look for cracks, leaks, or any other physical signs of deterioration that may be causing the drainage issue. If you notice any damage, it’s best to replace the drain pump to ensure optimal performance of your LG dishwasher.

Clearing Blockages In The Drainage System

To clear blockages in the drainage system of your LG dishwasher, start by removing any visible debris from the filter and the drain pump. Check for food particles, grease, or any other obstructions that may be blocking the flow of water through the system. Once the visible blockages are cleared, run a cycle with a dishwasher cleaner to eliminate any remaining buildup or residue that could be causing the drainage issue.

Inspect the drain hose for any kinks, bends, or clogs that may be preventing proper water flow. Detach the hose and clear out any debris using a pipe cleaner or a small brush. Ensure the hose is properly reattached once cleaned. Additionally, check the air gap, if applicable, to make sure it is not blocked or clogged. This is a common area for debris accumulation, so cleaning it thoroughly can help resolve drainage problems.

If blockages persist after cleaning the filter, drain pump, hose, and air gap, it may be necessary to check the drain pump for any signs of damage or malfunction. Contact a professional technician if the issue persists despite thorough cleaning and inspection to ensure proper diagnosis and repair.

Verifying The Air Gap Or Garbage Disposal Connection

When troubleshooting your LG dishwasher not draining, it is crucial to verify the air gap or garbage disposal connection. Start by checking the air gap, a device that prevents dirty water from re-entering the dishwasher. Ensure that it is not clogged with debris and that the hoses connected to it are not kinked or obstructed.

Next, if your dishwasher drains into a garbage disposal, examine the connection between the two units. If the connection is not done correctly, it can lead to drainage issues. Make sure that the knockout plug on the garbage disposal is removed if the dishwasher drain hose is connected to it. Additionally, check for any blockages or buildup in the disposal that might be causing the drainage problem. By verifying the air gap or garbage disposal connection, you can address potential issues that may be causing your LG dishwasher not to drain properly.

Evaluating The Drain Solenoid Or Drain Impeller

To evaluate the drain solenoid or drain impeller of your LG dishwasher, start by checking for any obstructions or debris that may be blocking the movement of these components. Inspect the drain impeller for any signs of damage or wear that might be hindering its functionality. Clean the impeller thoroughly and ensure it spins freely without any resistance.

Next, test the drain solenoid by listening for a clicking sound when the dishwasher enters the drain cycle. If no sound is present, the solenoid may be faulty and in need of replacement. Additionally, visually inspect the solenoid for any signs of corrosion or damage that could be affecting its performance.

If after these evaluations you find any issues with the drain solenoid or impeller, it is recommended to contact a professional technician for further diagnosis and repair. Proper functioning of these components is crucial for the effective drainage of water from your LG dishwasher, ensuring optimal performance and cleanliness of your dishes.

Assessing The Float Assembly

The float assembly in your LG dishwasher plays a crucial role in ensuring proper drainage. It is a small device located at the bottom of the appliance that regulates the water level during the wash cycle. If the float assembly gets stuck or malfunctions, it can prevent your dishwasher from draining properly.

To assess the float assembly, first, check for any debris or obstructions around the float mechanism. Clean any build-up carefully to ensure the float moves freely. Next, inspect the float itself for any signs of damage or corrosion. If the float is damaged, it may need to be replaced to restore proper drainage function.

Additionally, ensure that the float switch is functioning correctly. This switch is responsible for signaling the dishwasher to stop filling with water once it reaches the desired level. If the float switch is faulty, it can lead to drainage issues. By assessing and maintaining the float assembly in your LG dishwasher, you can troubleshoot and resolve problems related to drainage effectively.

Considering Electronic Control Or Sensor Issues

When all other common culprits for your LG dishwasher not draining have been ruled out, it may be time to consider electronic control or sensor issues. These components play a crucial role in regulating the various functions of your dishwasher, including the draining process.

First, inspect the electronic control board for any visible signs of damage or malfunction. Loose connections, burnt components, or water damage can all disrupt the proper functioning of the control board. If necessary, consult a professional technician to diagnose and repair any issues related to the electronic control board.

Additionally, faulty sensors can also prevent your LG dishwasher from draining properly. Sensors that are dirty or defective may not accurately detect the water levels in the dishwasher, leading to drainage problems. Cleaning or replacing the sensors as needed can help resolve this issue and get your dishwasher back to optimal performance.
