LG Dishwasher Error Codes

Although LG is known for producing top-notch appliances, your LG dishwasher may occasionally experience issues that prevent it from functioning correctly. Luckily, the dishwasher is designed to display an error code, which will indicate the source of the problem. By consulting our LG dishwasher error codes guide, you can independently identify and resolve the issue. However, if you are still trying to figure out how to fix the problem, it is recommended that you seek assistance from a trained technician.

Generally, error codes can be cleared by disconnecting the dishwasher’s power and water supply valve for several minutes.

The following article will explore several LG dishwasher error codes and their corresponding solutions. So, keep reading to find out more.

AE: Possible leak

If you see an AE error code on your LG dishwasher, it could indicate a leak. Even if you don’t see any visible signs of a leak, excess water may still be in the dishwasher’s base. This area is typically under the bottom panel and contains a basin and leak sensor.

Dishwashers may leak or trigger the leak sensor for various reasons, including using too much detergent, damaged spray arms, a damaged door gasket, or a blockage in the drain hose outlet or pump.

bE: Wrong detergent, or the dishwasher is not level

You may see a bE error code on the dishwasher display if you use dish soap instead of dishwasher detergent. To avoid this, make sure you use the appropriate detergent. If you have used the correct detergent and still see the error code, it’s possible that the dishwasher is not level. To fix this, use a leveling tool to ensure the dishwasher is level and adjust the leveling legs as needed.

If excess soap suds are in the dishwasher, the wrong detergent is used, which will also trigger the bE error code. LG recommends placing a bowl with 4-7 ounces of milk on the upper dish rack of the dishwasher and running an Auto cycle to remove the suds.

CE: Motor Error

If you see a CE error code on your LG dishwasher, it could mean that the motor is defective or that the motor wiring harness is loose. You can disconnect the dishwasher from the power to resolve the issue for ten seconds.

However, if the error code returns, you must check the motor and wiring harness to identify any faults. Depending on the issue, you may need to repair or replace the motor or its wiring harness to prevent the error code from appearing again.

FE: Fill Error

If you encounter an FE error code on your LG dishwasher, it means there is excessive water in the dishwasher. A defective water inlet valve, a faulty float switch, or a drainage problem can cause this issue. These are the most common reasons for the FE error code to appear.

HE: Heater Failure

If you see an HE error code on your LG dishwasher, it indicates that it could not heat the water or that the water temperature has exceeded 149 degrees Fahrenheit. This could be due to a failed heating element in the dishwasher. To resolve the issue, you will need to replace the dishwasher’s heating element.

IE: Slow or Inadequate Water Supply

When you encounter an IE error code on your LG dishwasher, it means that the water level in the dishwasher did not reach the required level after ten minutes of filling. This issue can occur due to poor water pressure, incorrect drain hose installation, or the dishwasher needs to be leveled.

LE: Motor Error

If you encounter an LE error code on your LG dishwasher, it indicates an issue with the motor. For more information on troubleshooting and fixing this error, please refer to the CE error code explanation above.

nE: Vario Motor Error

If you see an nE error code on your LG dishwasher, it means that there is a problem with the motor that controls the spray arms. To attempt to fix this error, you can disconnect the power to the dishwasher for a few minutes. If the error code disappears, the issue may have been resolved.

However, if the error code persists, you must check the motor using a multimeter to determine whether it has failed and needs to be replaced. Before replacing the motor, it’s essential to ensure that the error code is not caused by a loose wiring harness or a foreign object interfering with the motor.

OE: Drainage Problem

If you notice the display showing “OE” on your LG dishwasher, it indicates that it is facing difficulty draining the water. To resolve this error code, you can perform a few checks. These include looking for any food debris in the bottom of the dishwasher or its filter, ensuring that the dishwasher drain hose is not clogged or kinked, checking the air gap, and ensuring the drain pump is not clogged or defective.

PF: Power Failure

If you encounter a PF error code on your LG dishwasher, it suggests that there has been an interruption in the power supply. There could be various reasons behind this error code, such as a power outage and the dishwasher not having a dedicated circuit breaker of at least 120v, 60Hz, AC, and a minimum of 15 amps. Using an extension cord to power the dishwasher or improper grounding can also cause the PF error code.

To clear this error code, press any key on the control panel and wait 10 seconds for it to clear. If this does not work, you can try the power button and disconnect the power for a few minutes.

TE: Thermal Error

When you see a TE error code on your LG dishwasher, the water temperature has exceeded 194 degrees Fahrenheit, or there is an issue with the thermistor. In most cases, replacing the thermistor is necessary to fix the problem.

FAQs

What does CL mean?

The child lock or control lock feature has been activated if you see CL on your LG dishwasher’s display. To turn it off, you will need to refer to your dishwasher’s manual since the instructions vary depending on the model. However, some models have a Dual Zone button, which can be held down for three seconds to deactivate or activate the child lock.

For many LG dishwashers, the child lock is activated by choosing a cycle and then holding down the Rinse and Spray buttons for three seconds.

What does 2H mean?

Don’t worry if you notice 2H on your LG dishwasher display; it is not an error code. Instead, it indicates at least two hours left for the current cycle to complete. Once the remaining time for the new cycle reaches 99 minutes or less, the display will change to 99 and start counting until the cycle is finished.

What does a buzzing sound mean?

When you hear a buzzing sound after opening the dishwasher door, it indicates that the dishwasher’s interior is still very hot. This warning is normal if you have just completed a cycle. However, if the buzzing occurs when the temperature is not high, it may indicate a problem with the control board or temperature sensor, which may need to be replaced.
