Step 1: Initial Checks Before Troubleshooting

Before diving into the nitty-gritty of troubleshooting the HE error code LG dishwasher, I start with some basic checks.

First things first, I ensure that the water inlet hose is free from any clogs or blockages. It’s a simple step, but you’d be surprised how often it’s the culprit.

I also take a moment to inspect the water inlet valve for any signs of wear or defects.

Next, I verify that the water pressure from the main supply is up to snuff, meeting the recommended level for my dishwasher. The machine needs to function correctly. Additionally, I check the water level float switch to make sure it’s not stuck or malfunctioning.

If all these initial checks don’t reveal any issues, I might consider a reset to clear any temporary glitches that could be causing the error. It’s like giving the dishwasher a fresh start.

Here’s a quick list of the steps I follow:

1. Check the water inlet hose for clogs or blockages.
2. Inspect the water inlet valve for defects.
3. Verify the water pressure is at the recommended level.
4. Ensure the water level float switch is functioning properly.
5. Perform a reset if necessary.

LG Dishwasher heater circuit failure

turn off the power to it for like half a minute. Just flip the switch in your breaker box. This might reset any weird errors.

Next, check if the hot water’s getting to it. Feel the pipes – they should be warm. Make sure the hose ain’t bent or anything.

Now, this part’s a bit tricky. Turn off the power again and take out the bottom rack. Look at that metal coil thingy at the bottom. If it looks rusty or broken, that’s probably your problem.

If that looks okay, you might need to open up the door panel. Check all the wires in there. If any look is melted or gross, that could be why it’s not heating.

If all that stuff looks good, it might be the control board acting up. That’s the brains of the dishwasher. It might not be telling the heater to turn on.

Step 2: DIY Fixes for the HE Error Code

Fix 1: Test the Heating Element

1. Turn off power at the circuit breaker.
2. Remove the dishwasher’s lower access panel.
3. Locate the heating element (a metal coil at the bottom).
4. Use a multimeter to test for continuity. No continuity = replace the element.

Fix 2: Inspect the Thermostat

1. Disconnect power.
2. Locate the thermostat (near the heating element).
3. Test with a multimeter. If it doesn’t register, replace it.

Fix 3: Clear Blocked Vents or Pipes

• Check the ventilation system for obstructions.
• Ensure the drain hose isn’t kinked or clogged.

Personal Experience

My LG dishwasher started acting up recently, showing an “HE” error, which means there’s a problem with its heating.

So, I took a look inside by flipping it and taking off the bottom cover. I found out that the heating element’s connection had gone bad due to rust.

I checked and found the heating element itself is fine. I even fixed it temporarily by attaching a new connector, and it worked. Now, I want to fix it for good.

The part I need to replace is a small connector attached to a ceramic base with two metal connectors sticking out.

This part isn’t listed by itself in the manual; it’s included in the whole pump assembly, which costs between $200 and $300. But since the heating element is still good, I just want to replace the connector.

The connector is 17mm wide with metal connectors sticking out on both sides.

On the back, I found some numbers that might help identify it, but I’ve had no luck finding it online:

155 131 003 23 16 260C

If anyone knows where I can find this part or anything about it, I’d appreciate the help. Thanks!
