LG Dishwasher F35 Error Code

If your LG dishwasher is displaying F35, this guide explains what it means,
what you can safely check, and when professional diagnosis may be needed.

What does F35 mean on a LG dishwasher?

Heat Dry temperature-related error.

Definitions can vary by model or platform, so compare the code with information for your exact model before replacing parts.

What you can try

Power-cycle the dishwasher. If the code returns, professional diagnosis of the Heat Dry system is recommended.

Before booking a repair

1. Confirm the displayed error code and your appliance model number.
2. Check relevant external issues such as a blocked filter, kinked hose, open door, interrupted power, or restricted airflow.
3. If a power reset is appropriate for the appliance, turn it off safely and restart it once.
4. If the code returns, avoid repeated resets and arrange diagnosis.

Safety note

Disconnect electrical power before accessing internal components.
Do not open sealed, gas, high-voltage, or refrigerant systems unless qualified to service them.
These steps are general guidance and do not replace service information for your exact model.
