If your LG dishwasher is not draining water, there are several possible reasons, including a clogged drainage system, a broken drain impeller, a faulty drain pump, or a clogged garbage disposal or drain hose. To resolve this issue, you can try manually draining the dishwasher by pressing and holding the cancel and drain button, if available. If your model lacks this button, running a normal cycle for approximately 45 seconds can initiate draining. If these steps don't work, you may need to investigate further and address any clogs or faulty components. In some cases, you may need to reset the dishwasher or consult a technician for more complex issues.

How to fix an LG dishwasher AE error code
An AE error code on an LG dishwasher means there is a leak inside your dishwasher that has activated the float switch. Before you can use your dishwasher again, you must find and fix the underlying cause of the leak.
To fix an AE error code, first try resetting your dishwasher. Sometimes, the error code can appear accidentally or due to a problem with the control board. To reset your dishwasher, turn the power off for 10 minutes and then turn it back on.
If the error code persists, open the dishwasher and place a level inside against the top, sides, and bottom of the unit to ensure it is level. Remove the bottom rack and pour about a gallon of water into the bottom of the dishwasher. If the water pools to one side, the unit is not level. Adjust the screws at the bottom front of the dishwasher to raise and lower the back legs.
If the unit is level, check the door gasket (also called a seal) for any damage or debris. If the gasket is damaged, it will need to be replaced. If it is dirty, clean it with hot soapy water. Once the gasket is cleaned or replaced, check if the error code is still showing.
If the error code remains, check the water inlet valve. The water inlet valve is the next component to check if the AE error code is still showing. If the error code persists after checking the water inlet valve, request a repair with LG's 24/7 Chat Support.
If you are using only one pod or tablet and an AE error code is displayed, the unit will need to be examined by a technician.

How to reset an LG dishwasher
If your LG dishwasher is not draining water, there could be several reasons. The drainage system may be clogged, or the drain basket may need to be cleaned. You can use a plunger or a plumber's snake to clear the blockage. Another reason could be that the drain impeller is broken, the drain pump is not working, or the drain solenoid kit has failed. If the issue is with the drain pump, you will need to replace it.
Now, to reset an LG dishwasher, you can perform a soft reset, which is the simplest way to restart the appliance when it becomes unresponsive. Start by turning off the dishwasher using the Power button. If it is not responding, unplug it from the power outlet. For hardwired models, switch off the circuit breaker supplying power to the dishwasher. After powering down, wait for around 10-15 minutes to let any remaining electrical charge dissipate from the control board. Then, plug the dishwasher back in and turn it on to reboot the system.
If your LG dishwasher is connected to a smart home system, ensure that the Wi-Fi settings are correctly configured. Some models may require re-establishing a connection after a reset, which can be done through the LG ThinQ app.
If your dishwasher is showing an AE error code, it means water has been detected in the base of the unit, and a float has been triggered to prevent further leaks. To reset it, clear the water and find the source to prevent the code from returning. Push down on the styrofoam part of the float to ensure it is clear, and reset the power to the board, leaving it off for at least a minute. If the float is clear and the code persists, the float switch or the board itself may be defective.
If your LG dishwasher is showing an E1 error code, it means there is a leak inside your dishwasher activating the float switch. To reset the dishwasher, you will need to find and fix the underlying cause of the leak.

How to unclog a dishwasher
A dishwasher that isn't draining properly can be a real inconvenience, and there are several reasons why this might be happening. Firstly, it's important to note that you should always unplug your dishwasher and turn off the water supply before attempting any repairs or unclogging methods.
Common Causes of Clogged Dishwashers
Dishwashers can become clogged for various reasons, including a faulty drain pump, a broken drain impeller, a clogged drain hose, or a blocked filter.
Unclogging Methods
- Check the Control Panel: Some LG dishwashers have a "cancel and drain" button. Press and hold this button to initiate the draining process. If your dishwasher doesn't have this option, start a normal cycle and let it run for about 45 seconds. The first 45 seconds of an LG dishwasher cycle are used to drain the system.
- Use a Plunger or Snake: If your dishwasher has a clogged drainage system, you can use a plunger or a plumber's snake to clear the blockage.
- Clear the Drain Basket: Remove and clean the drain basket if your dishwasher has one. Flat items like plastic bits can block the basket, causing the dishwasher to back up.
- Inspect the Drain Hose: The drain hose connects the dishwasher's drain pump to the disposal or air gap and your sink drain. Kinks or clogs in the hose can prevent water from draining properly. Straighten any visible kinks and ensure the hose is away from objects that might push against it. If the hose is clogged, disconnect it from the drain pump and remove the clog with a wire hanger.
- Run a Hot Cycle with Vinegar: If your dishwasher is draining slowly, run it empty on the hottest water setting. Instead of detergent, add a cup of vinegar to the dishwasher. This can help melt any blockages in the drain.
- Clean the Spray Arms: Remove the upper and lower spray arms and check the holes for clogs. Use a toothpick or a small piece of wire to clear any blockages. Run water through the spray arms to ensure they are clear.
- Deep Cleaning Cycle: After clearing visible clogs, perform a deep cleaning cycle. Place a bowl of white vinegar or a bottle of dishwasher cleaner on the top shelf of the dishwasher. Set it to the self-cleaning cycle or the hottest possible cycle if there is no self-cleaning setting. Run the cycle with nothing else in the dishwasher.
If the problem persists, you may need to consult a professional repair service to diagnose and resolve the issue.

How to fix a leaking LG dishwasher
If your LG dishwasher is leaking, there are several potential causes and solutions. Firstly, check if there is an error code displayed on the dishwasher's control panel. An AE or E1 error code, for example, indicates a leak inside your dishwasher that has activated the float switch.
To fix a leaking LG dishwasher, you can try the following methods:
Check the levelling:
First, check if your dishwasher is level. Remove the bottom rack and pour about a gallon of water into the bottom of the dishwasher. If the water pools to one side, your dishwasher is not level. Adjust the levelling screws to ensure the unit is level, following the manufacturer's instructions.
Inspect the door gasket:
The door gasket or seal is made of soft rubber or vinyl and creates a watertight seal around the door or tub opening. Over time, the gasket may become damaged, worn, or less flexible, causing leaks. Inspect the gasket for any issues and replace it if necessary.
Examine the water inlet valve:
The water inlet valve supplies water to the dishwasher and could be the source of a leak. Disconnect the appliance from the power and water source, then remove the lower access panel to access the valve. Inspect the valve for any signs of damage or wear, and replace it if necessary.
Check the drain hose:
The drain hose carries wastewater from the dishwasher to the sink drain. If the hose is damaged or has a hole, it could cause a leak. Inspect the hose and replace it if necessary.
Inspect the pump and pump seal:
The pump circulates water and, in some models, drains water from the dishwasher. A defective pump or pump seal can cause leaks. Disconnect the power and locate the pump behind the lower access panel. Remove and test the pump for continuity using a multimeter. If the pump is defective, replace it.
Clear blockages:
A clogged drainage system, garbage disposal, or drain hose can cause water to back up and leak. Use a plunger or a plumber's snake to clear any blockages.
Dry the drain pan:
If your dishwasher displays an AE or E1 error code, it may be due to water in the drain pan. To resolve this, open the kick plate and leave it off for 24-48 hours to allow the water to evaporate. Then, reset the dishwasher by turning off the circuit breaker and turning it back on. Run an empty cycle to complete the process.

How to repair an LG dishwasher that won't drain
If your LG dishwasher isn't draining properly, there are several possible reasons. One common cause is a clogged drainage system, which can be cleared using a plunger or a plumber's snake. Another reason could be a clogged filter, which can be fixed by removing and cleaning the filter. Running the disposal before starting the dishwasher can also help clear any lingering food particles.
If your LG dishwasher has a broken drain impeller, faulty drain pump, or failed drain solenoid kit, you will need to replace these components. Before attempting any repairs, unplug the dishwasher and turn off the water supply. Work gloves and safety goggles should always be worn during the replacement process.
