How to Fix the LG Dishwasher HE Error Code: Complete Troubleshooting Guide

The LG dishwasher HE error code usually indicates an issue with the heating element or water levels. Follow the troubleshooting steps to resolve the issue, including checking the water level, resetting the dishwasher, and inspecting the heating element. If the problem persists, consider professional help.

What Does the LG Dishwasher HE Error Code Mean?

When an LG dishwasher displays the HE error code, it typically points to a problem with the heating element or water levels. This error prevents the dishwasher from completing the wash cycle because the water isn’t being heated to the correct temperature, which is necessary for effective cleaning and drying.

Understanding the cause of this issue is crucial to resolving it quickly. The HE code on LG dishwashers can be triggered by several factors, ranging from something as simple as low water levels to more complex issues, such as a malfunctioning heating element or wiring problems.

Common Causes of the HE Code in LG Dishwashers

There are a few common reasons why the HE code might appear on your LG dishwasher. Knowing these causes will help you identify the source of the problem.

1. Heating Element Failure

The heating element is one of the most common culprits when it comes to the HE code on LG dishwashers. This component is responsible for heating the water during the wash cycle. If the heating element malfunctions or burns out, the dishwasher will trigger the HE error.

Signs of a faulty heating element:

• The dishwasher fails to heat water.
• The dishwasher is not drying dishes effectively.

2. Water Level Issues

Another common reason for the LG dishwasher HE error code is an issue with the water level. If the dishwasher is not filled with the correct amount of water, the heating element cannot function properly. This could be caused by a clogged water inlet valve, drain hose issues, or a faulty float switch.

How to check water levels:

• Open the dishwasher and check for standing water.
• If the water level seems too low, inspect the inlet valve and drain hose for blockages.

3. Faulty Door Latch

A malfunctioning door latch may also trigger the HE error. If the door latch is not sealing properly, the dishwasher’s internal systems, including the heating element, may not function correctly. You’ll need to inspect the latch and ensure it’s properly aligned and working.

Step-by-Step Troubleshooting for the HE Error Code

If your LG dishwasher displays the HE error code, here’s how to troubleshoot the issue step by step:

1. Check the Water Level

First, ensure there is enough water in the dishwasher. If the water level is too low, the heating element may not operate properly, causing the HE code on your LG dishwasher.

• DIY Fix: Inspect the water inlet valve and the float switch to ensure they are functioning properly. If you see any blockages, clear them out.
• Tip: Sometimes, the water supply can get clogged with mineral deposits or debris, leading to water flow issues.

2. Reset the Dishwasher

A simple reset can sometimes clear the HE error, especially if it was caused by a temporary glitch. To reset the dishwasher:

• Unplug the dishwasher for about 5-10 minutes.
• After the reset, plug it back in and check if the error code clears.

Tip: If the HE error code persists after resetting, it’s likely that the issue is not a temporary glitch.

3. Inspect the Heating Element

The heating element is crucial for the dishwasher’s ability to clean and dry dishes. If the heating element fails, the dishwasher cannot heat the water, which triggers the HE error code.

• DIY Fix: Test the heating element for continuity using a multimeter. If there is no continuity, the heating element needs to be replaced.
• Professional Help: If you’re not comfortable testing electrical components, it’s best to call a professional to handle the inspection and replacement

4. Check the Door Latch

The door latch could also be the source of the problem. If the latch is not engaging properly, it can trigger the HE error code.

• DIY Fix: Inspect the latch to see if it’s misaligned or damaged. If the latch isn’t functioning, you may need to replace it.
• Pro Tip: Ensure the door is fully closed and the latch clicks into place when you start the cycle.

When to Call a Professional for Help

If you’ve followed the troubleshooting steps and the HE error still won’t clear, it may be time to call in a professional technician. There are cases when the issue goes beyond basic fixes, such as when there’s:

• A malfunctioning control board.
• Complex wiring issues.
• Worn-out components that require professional expertise to replace.

Signs that you need professional help:

• The HE error persists after multiple resets.
• You’re unable to identify or fix the issue yourself.
• The cost of parts and time required to fix the issue may justify professional help.
