First, ensure the dishwasher is powered off. Press and hold the “Heated Dry” and “Start/Reset” buttons simultaneously. While holding, press the “Power” button to turn on the machine. Keep holding the other buttons for about 3 seconds. Release all buttons once the display changes. The dishwasher will enter diagnostic mode.

The display will show a code or flashing lights. You may hear a short beep sound. The cycle indicator lights might blink in a pattern. These signs confirm the dishwasher is in diagnostic mode. If you see normal washing cycles, the mode did not activate.
Common Entry Issues
The buttons might not be pressed exactly at the same time. Holding buttons for too long or too short can fail activation. Power interruptions during the process cause errors. Older models may have different button sequences. Refer to your user manual for specific instructions.
Using Smart Diagnosis

Your dishwasher sends sound codes to the service agent. They listen and identify the issue based on these tones. This method works well if you cannot use the app.
Connecting Devices To Wi-fi

Interpreting Error Codes
Interpreting error codes on your LG dishwasher helps identify issues quickly. These codes appear during diagnostic mode. Understanding them saves time and guides proper fixes. Each code points to a specific problem inside the dishwasher. Knowing what they mean allows you to act correctly. This section breaks down common codes and how to respond.
Common Lg Dishwasher Codes
LG dishwashers show error codes like OE, IE, UE, and HE. OE means a drainage problem. IE signals water inlet issues. UE points to unbalanced loads. HE stands for heating errors. These codes flash on the display to alert you. Recognizing these codes helps spot the exact fault fast.
What Each Code Means
OE means the dishwasher cannot drain water properly. It may be clogged or have a faulty pump. IE shows water is not entering the machine. Check the water supply or valve. UE occurs when dishes are unevenly placed or the load is too light. HE indicates the heater is not working. This affects drying performance.
How To Respond To Codes
For OE, clean the drain filter and hose. Clear any blockages to restore flow. For IE, ensure the water tap is open and hoses are connected. Fix kinks or replace damaged parts. For UE, rearrange dishes evenly and avoid light loads. Run the dishwasher again. For HE, check the heating element and wiring. Call service if unsure.
Troubleshooting Common Issues
LG dishwashers offer diagnostic mode to help identify and fix common problems. This mode allows users to check the machine’s functions quickly. It saves time by pointing out specific issues. Understanding typical problems improves maintenance and performance.

Door Latch Malfunctions
Ensure the door closes firmly and the latch clicks. A faulty latch stops the dishwasher from starting. Diagnostic mode tests the door switch sensor. Replace damaged latches to restore proper operation.
