LG dishwashers display error codes when they have problems. You can find the error codes in the user manual. However, if you see the HE error code, this guide will tell you everything you need to know.
The HE error code on an LG dishwasher means there is a heater fault. It kicks in when the dishwasher overheats above 149 degrees Fahrenheit or doesn't heat up at all. First restart the dishwasher to see if it clears the code. If not, troubleshoot the thermistor, heater, and main control board.
This guide will walk you through the HE error code troubleshooting process. By the end you will know why this is happening and how to fix it.
What does the HE error code mean on an LG dishwasher?
The HE error code on your LG dishwasher means there is a problem with the machine's heater.
Two conditions can cause the HE error code to appear:
- without hot:Your dishwasher needs to be hot for effective cleaning. However, if there is no heat, the HE error code will be triggered.
- Excessive heating:While heat is necessary, overheating is dangerous for your device. Therefore, the HE trouble code will also activate when temperatures exceed 149 degrees Fahrenheit.
Both of the above conditions prevent you from using the dishwasher properly. Hence, you need to troubleshoot and fix the problem as soon as possible.
The next section will help you with that.
How to Fix HE Error Code on LG Dishwasher?

File: 5 LG dishwasher problems you should know about
About it:AThermistor is a temperature sensor in your LG dishwasher.Its purpose is to measure how hot or cold the dishwasher is and relay that data to the main control panel.
When the data indicates the water is still cold, the main control board sends power to the heater. This stops once the thermistor detects the water is hot enough for the dishwasher to prevent overheating.
To trigger the HE error:The thermistor will trigger the HE error code when faulty. This is because it cannot measure the correct temperature inside the device. As a result, incorrect data will be sent to the main control board.
Depending on the data the faulty thermistor is sending, the dishwasher will either not heat up or will overheat to dangerous temperatures.
The HE error code will activate in both cases.
How to fix it:Fixing this problem is as simple as replacing the faulty thermistor. Unfortunately, once the thermistor stops working properly, you cannot restore or repair it.
Carefully disconnect the thermistor leads before removing them. You must be careful not to damage the wires as you will be connecting them to the new thermistor you are installing as a replacement.
File:How to fix LG dishwasher without power?
About it:A crucial component that is not often discussed is the heater, also called'Radiator'. You can find this component at the bottom of the compartment and it connects to the dishwasher at both ends.
The heater consists of materials with high electrical resistance. When power is supplied to the heater, this resistance causes the power to be converted to heat.This heats up the rinsing water and helps to clean kitchen utensils more effectively.

To trigger the HE error:Heater elements can also fail and trigger the HE error code. These problems are usually caused by electrical faults such as short circuits and physical damage caused by heavy objects falling onto the heating element.
For example, a defective heating element heats only partially or not at all. This leads to a lack of heat that triggers the HE error code.
On the other hand, a shorted heating element will continue to generate heat even when it shouldn't.This causes it to overheat above 149 degrees Fahrenheit, which also triggers the HE error code.
How to fix it:Heating elements are another dishwasher component that needs to be replaced when they stop working properly. It's best to replace it as soon as possible, even if it generates a little heat.
The replacement process is very simple. First disconnect the heating element at both ends and remove it from the device. Then connect the new heater in the same way.
File: How to Fix LE Error Code on LG Dishwasher?
About it:Everything your LG dishwasher does is controlled by the main circuit board (PCB), also known as the main control board.This circuit board has components that send and receive electrical signals to parts of the machine to properly wash your dishes.
To trigger the HE error:The main control panel is the heart of your dishwasher. Any failure or defect in the main circuit board will cause your dishwasher to behave abnormally.
Unfortunately, this means that you could also falsely trigger the HE error code even though all of your components are working correctly.
How to fix it:It is possible to fix individual components on the circuit board. It's not a practical solution, however, as the individual parts can be difficult to find, let alone replace.
The best way to get your dishwasher working again is to buy a new LG control board and replace the one you already have.
