Common LG Dishwasher Error Codes & Malfunctions
The most common LG dishwasher error codes are as follows.
Error code IE
The LG dishwasher IE error code refers to an inlet error, leading to the dishwasher not reaching its normal water level.
How to solve it:
First off, check that the water supply cut-off valve is fully open. If it is, check the water inlet supply hose for potential kinks. If there is no problem, the next step is to unplug the dishwasher and disconnect the supply hose from the inlet water valve. This allows you to check the filter screen on the valve for potential clogs. If the filter is clogged, you have to replace the valve. Otherwise, place the end of the hose in a container and briefly open the water supply valve to determine if there is a problem with the water flowing through the hose.
If there is no problem with the water flow, you have to check the inlet guide assembly for potential clogs. Clear any clogs. If there are no clogs, please request a quote to get service.
Error code OE
The OE error code refers to a drain error, leading to water not draining from the dishwasher.
How to solve it:
Inspect the sink drain or garbage disposal for clogs and clear any clogs present. In the absence of clogs, pull off the dishwasher drain hose from its connection and check the end of the drain hose for a grease clog. Clear any grease clogs present. The same goes for the air gap, which could be clogged depending on the model.
If none of these steps solve the problem, unplug the dishwasher, check the entire drain hose between the drain pump and the sink drain connection for clogs, and clear any drain hose clogs. The next step would be to check the dishwasher sump and drain pump for clogs and remove any clogs. If the sump and drain pump are clear, please call our customer service to request service.
Error codes AE or E1
Low water levels in the tub can cause an abnormally high circulation pump speed, leading to an LG dishwasher AE or E1 error code. Water leaking into the base of the dishwasher cabinet and tripping the flood switch is another cause for the error.
How to solve it:
Unplug the dishwasher and shut off the water supply before checking the cabinet base for water to solve this error. If you find water, you have to check and fix the cause of the leak. Potential sources of leaks are the water fill line, water inlet guide, drain pump, drain hose, door seals or sump. Remove the water from the cabinet base after you have fixed the leak.
If there is no leakage, please call our customer service to request service.
Error code bE
This error code can indicate either a problem with your dishwasher’s levelling or using an improper detergent.
How to solve it:
Check if your dishwasher is levelled front to back and side to side. If this is not the problem and you have excess suds in your dishwasher, it could be due to the wrong detergent. Never use hand-washing liquid detergents but only automatic dishwasher detergents.
To eliminate suds, place 4-7 ounces of milk in a shallow bowl into the upper rack of your dishwasher and run an AUTO cycle. The fat in the milk will bond the suds and allow your dishwasher to rinse out correctly.
Error code FE
The error code FE points to the dishwasher filling above the normal water level and that the automatic drain pump has been activated.
How to solve it:
Turn off the dishwasher, then turn off the circuit breaker to the dishwasher and wait 10 seconds before turning it back on. Turn the dishwasher back on and start a new cycle. If the problem persists, please call our customer service to request service.
Error code tE
This error code refers to a thermal error, indicating an abnormal thermistor resistance output.
How to solve it:
Please call our customer service to request service.
Error code HE
An HE error code is displayed if the water in the dishwasher is either not heated at all or if the temperature has risen above 194°F.
How to solve it:
Turn off the dishwasher, then turn off the circuit breaker to the dishwasher and wait 10 seconds before turning it back on. Turn the dishwasher back on and start a new cycle. If the problem persists, please call our customer service to request service.
Error codes LE or CE
The LE or CE error codes indicate a problem with the dishwasher’s motor. It could be a problem with the motor or the wiring harness between the motor and the motherboard.
How to solve it:
Turn off the dishwasher, then turn off the circuit breaker to the dishwasher and wait 10 seconds before turning it back on. Turn the dishwasher back on and start a new cycle. If the problem persists, please call our customer service to request service.
Error code nE
This error code is displayed when a vario error occurs. It means the Vario motor that controls the spray arms is not working correctly.
How to solve it:
Please call our customer service to request service.
Error code PF
The PF error code indicates a power failure.
How to solve it:
Ensure that the dishwasher is powered by a dedicated circuit breaker at 120v, 60Hz, AC only, with a minimum of 15 amps. Also, do NOT use extension cords and ensure the appliance is grounded.
