Fault codes, also called error codes or fault codes, allow your device to automatically report an internal malfunction. Below you will find the list of fault codes for your LG dishwasher and their meaning: this will give you an indication to best diagnose the origin of the malfunction of your appliance and identify the faulty component.
The error code can be read directly on the front panel of your LG dishwasher. Depending on the model, you can read this code on a display (for example, “Err 01”) or by observing the number of LED flashes (for example: 4 LED flashes = “Err 04”).
Refer to the user manual for your LG appliance to find out the exact meaning of the fault code displayed or the lights that flash. The number of flashes often corresponds to the error code number, but there are specificities linked to each model and brand.
The fault codes displayed by your LG dishwasher can be erased by pressing and holding the start/pause button for at least 5 seconds. The device can then start its normal cycle.
OE ERROR CODE – WATER PUMPING AND DRAINING
This trouble code indicates that water is not being pumped and drained in your dishwasher. The causes of this problem can be various:
- The drain hose may be kinked. In this case, straighten it.
- The filter may also be clogged. A good cleaning is enough to solve this problem.
- The motor (main motor or that of the drain pump) has a fault. Please note that the dishwasher drain pump extracts waste water from washing and rinsing from the appliance. It is generally located at the lowest point of the device to drain a maximum quantity of water (near the tank).
IE ERROR CODE – WATER INLET
This error code indicates that water is not reaching the device. Several causes can be at the origin of this failure.
- You may have forgotten to turn on the tap. You always have to check it.
- The water inlet valve can be blocked by the safety device to avoid any risk of leaks.
- Remember to always check the condition of your solenoid valve which is responsible for filling the device.
ERROR CODE EI – WATER LEAK
The EI fault code is displayed on your machine when the drain pump has automatically worked and there is probably a water leak at the hose connections. Turn off the water supply then unplug your dishwasher. Next, two things need to be checked:
- Condition of the door seal
- The condition of the cycling pump hose (this is the dishwasher motor). If the fault comes from the dishwasher’s cycling pump, it must be changed.
ERROR CODE FE – WATER QUANTITY
This fault code signals an abnormal increase in the quantity of water in your dishwasher.
The solenoid valve, which allows or interrupts the circulation of water, is in difficulty. This part is therefore no longer able to function correctly. In such a problem, it is advisable to turn off the water supply and then unplug the device.
ERROR CODE HE – HEATING CIRCUIT
This fault code indicates that the heating circuit of your dishwasher is not working properly. Here are the causes that can cause this problem:
- The dishwasher resistance may be covered in limescale: replace it. The role of the resistance is to heat the water.
- The klixon is defective. The klixon is a temperature safety device. If the temperature of the dishwasher is abnormally high, the klixon opens the circuit as a protection.
- The threads of resistance are about to be broken.
- The resistor terminals have poor contact.
ERROR CODE TE – THERMISTOR
This fault code indicates a heating problem. The thermistor may be defective or the supply water temperature may be abnormally high.
- Check that the water level inside is correct. This should be approximately flush with the bottom of the salt pot cap.
- Also, you must always check that the thermostats are located under the tank close to the resistance.
ERROR CODE LE – MOTOR
This fault code indicates a problem with your dishwasher’s motor. The failure is probably due to overload.
ERROR CODE PF – POWER FAILURE
This code is displayed when a power outage has occurred. This secures your device in the event of a power outage. This code only displays for up to 10 seconds after power is restored.
CD ERROR CODE – ADDITIONAL DRYING CYCLE
This code indicates the start of an additional drying cycle. This helps optimize the drying performance of your dishwasher.
CL ERROR CODE – CHILD SAFETY
This fault code represents the child safety of your dishwasher. It allows you to lock and unlock the control buttons. Your machine is therefore only activated during the wash cycle.
ERROR CODE F – WATER CLARITY
When this message is displayed on your machine’s screen, a sensor is measuring water clarity. After running for 5 minutes, the display shows the processing time.
LO: Low Water Error
The dishwasher detects that the water level is too low, which might be due to issues with the inlet valve or leakage.
HS: Heat Sink Overheating
The heat sink on the control board is overheating, indicating a potential problem with the control board or its components.
LS: Water Leakage Sensor Error
The sensor that detects water leaks in the dishwasher is malfunctioning or a leak has been detected.
SS: Salt Refill Reminder
This indicates that the dishwasher requires a salt refill for its water softener system (common in certain regions or models).
DE2: Door Closing Error
The dishwasher door is not closing properly, which might be due to an obstruction or a misalignment of the latch.
CD: Cooling Down Issue
The dishwasher is taking longer than expected to cool down after the heating cycle.
UD: Unexpected Draining
The dishwasher is draining water when it’s not supposed to, indicating a potential issue with the control system or a faulty sensor.
FL: Flow Meter Error
The flow meter, which measures the amount of water entering the dishwasher, is malfunctioning.
FD: Door Feed Error
There’s an issue with the detergent dispenser door; it might not be opening during the wash cycle.
DR: Drying Error
The dishwasher encountered a problem during the drying phase, which could be due to a malfunctioning fan or heater.
DE1: Door Open Error
The dishwasher detects that the door is open during operation.
3C: Drain Motor Issue
The drain motor is either running continuously or not operating when required.
4C: Wash Motor Issue
The wash motor is malfunctioning or not running during the wash cycle.
6C: Diverter Valve Error
The diverter valve, which directs water to different zones within the dishwasher, is malfunctioning or stuck.
DC: Detergent Dispenser Error
There’s an issue with the detergent dispenser, like not being able to release detergent during the wash cycle.
UC: Current Overload
The dishwasher’s motor is drawing too much current, indicating a potential fault in the motor or its circuitry.
The dishwasher detects an over-capacity load or excess foam during the wash cycle, which can interfere with proper washing.
PA: Abnormal Water Temperature
The water temperature in the dishwasher is outside the normal range, indicating a possible heater or sensor issue.
HH: Heater Overheating
The dishwasher detects that the heating element is overheating, which could be due to a malfunctioning thermostat or heater element.
2H: Delay Start
The dishwasher is in delay start mode. This isn’t necessarily an error, but a reminder or status code.
