How do I fix the he error on my LG dishwasher?

Understanding the HE Error Code

1.1. Heating Problem Indication

The HE error code on an LG dishwasher indicates a heating issue with the water used during the dishwashing cycle. It suggests that the dishwasher is unable to heat the water to the desired temperature necessary for effective cleaning and sanitization.

 

1.2. Potential Causes

The HE error can be triggered by several factors, such as a faulty heating element, a malfunctioning temperature sensor, or an issue with the water supply and connections.

Initial Troubleshooting Steps

2.1. Restart the Dishwasher

Begin by restarting the dishwasher. Sometimes, system glitches can trigger error codes. Turn off the dishwasher, unplug it from the power source, and wait for a few minutes. Then, plug it back in and restart the dishwasher to see if the error code clears.

 

2.2. Check for Obstructions

Inspect the dishwasher’s spray arms, filters, and pump for any debris or blockages. Clear away any visible obstructions that may hinder the proper functioning of the dishwasher.

 

Inspect the Heating Element

3.1. Visual Examination

Locate the heating element, typically found at the bottom of the dishwasher’s tub. Inspect the element for any visible signs of damage, such as burn marks, corrosion, or breaks. A damaged heating element may cause the HE error.

 

3.2. Check for Continuity

Use a multimeter to test the continuity of the heating element. Remove the element from the dishwasher following the manufacturer’s instructions. Set the multimeter to the continuity or ohms setting, and place the multimeter prongs on the terminals of the heating element. If there is no continuity or a very high resistance reading, the heating element is likely faulty and needs to be replaced.

 

Verify the Water Supply

4.1. Check the Water Inlet Valve

Inspect the water inlet valve, usually located behind the dishwasher’s bottom kickplate or on the side of the unit. Ensure that the valve is not clogged or restricted. Cleaning the valve or replacing it, if necessary, can resolve water supply issues that could trigger the HE error.

 

4.2. Test the Water Temperature

Verify that the water entering the dishwasher is at an appropriate temperature. Run hot water in your kitchen sink faucet, then test the water temperature using a thermometer. The temperature should ideally be around 120°F (49°C) for optimal dishwasher performance. Adjust your water heater if necessary.

Check the Temperature Sensor

5.1. Sensor Location

Locate the temperature sensor, often located near the heating element or at the bottom of the dishwasher’s tub. The sensor monitors the water temperature during the dishwashing cycle.

 

5.2. Sensor Inspection

Inspect the sensor for any visible damage or corrosion. Clean the sensor with a soft cloth or a cotton swab dipped in rubbing alcohol to remove any debris or contaminants.

 

5.3. Test Sensor Continuity

Using a multimeter set to the continuity or ohms setting, test the sensor for continuity. Disconnect the sensor from the wiring harness and place the multimeter prongs on the sensor’s terminals. If there is no continuity or an abnormal reading, the temperature sensor may be faulty and should be replaced.

Reset the Control Board

6.1. Power Off and On

Resetting the dishwasher’s control board can help clear any temporary system issues that may be causing the HE error. Turn off the dishwasher and unplug it from the power source. Wait for a few minutes before plugging it back in and restarting the dishwasher.

 

6.2. Factory Reset

Performing a factory reset may also resolve certain control board-related issues. Consult your dishwasher’s user manual for instructions on how to perform a factory reset, as the method may vary depending on the specific model.

 

Seek Professional Assistance

7.1. Manufacturer Support

If the troubleshooting steps mentioned earlier do not resolve the HE error on your LG dishwasher, consider contacting LG’s customer support for further assistance. They can provide specific guidance based on your dishwasher’s model and the error code displayed.

 

7.2. Professional Repair Service

If you are unable to resolve the issue on your own, contacting a professional appliance repair service is recommended. Certified technicians have the necessary expertise to identify and address complex problems with your dishwasher, including the HE error. Before asking for help, check if the product is under warranty.

 

Preventive Maintenance

8.1. Regular Cleaning and Care

To prevent recurring issues and maintain optimal performance, it is important to practice regular cleaning and care for your dishwasher. Clean the filters, spray arms, and other components regularly to prevent clogs and ensure efficient water circulation.

 

8.2. Proper Loading Techniques

Avoid overcrowding the dishwasher and ensure that dishes, utensils, and cookware are loaded correctly. Overloading can obstruct the water flow and prevent effective cleaning and heating.

 

8.3. Use Quality Detergent

Choose a high-quality dishwasher detergent that is specifically designed for your dishwasher model. Using the proper detergent can improve cleaning performance and reduce the likelihood of errors.
