Cause of LG Dishwasher HE Error Code
The HE error code on an LG dishwasher typically indicates a heating error. The possible causes of the HE error code can include:
Defective temperature sensor: The dishwasher's temperature sensor monitors the water temperature during the wash and drying cycles. If the temperature sensor is faulty or sends incorrect readings, it can cause the HE error.
Control board issue: A problem with the dishwasher's control board, which controls various functions and processes, can lead to the HE error code. A malfunctioning control board may not properly regulate the heating element or receive accurate readings from the temperature sensor.
Water temperature issues: If the hot water supply to the dishwasher is not at the recommended temperature, it can prevent the dishwasher from reaching the desired temperature during the wash or drying cycles. Inadequate water temperature can trigger the HE error.
Wiring or electrical problems: Faulty wiring connections or electrical issues within the dishwasher can disrupt the heating element's operation, leading to the HE error.
It's important to note that the specific cause of the HE error code may vary depending on the model and specific circumstances. Consulting the dishwasher's user manual or contacting LG customer support can provide more precise information and guidance for troubleshooting the issue.
