Why Is My LG Dishwasher Error Code 6E Showing?

Faulty steam sensor

Steam sensor may be malfunctioning or defective, causing the 6E error to appear. This sensor monitors the steam levels during the steam cycle.

Solution

It’s usually close to the steam nozzle inside the dishwasher tub.

Next, unplug the wiring harness from the steam sensor. Grab a multimeter, set it to the ohms setting, and touch the probes to the sensor terminals.

Check the resistance—it should match the range in the service manual. If it’s out of range or shows no continuity, time to replace the sensor.

If sensor is good, reconnect the wiring harness and look for any loose, damaged, or corroded connections. If wiring seems fine, the problem might be with the control board.

This board sends power to the steam sensor and keeps an eye on its operation. If it’s faulty, a qualified technician needs to replace it.

Clogged steam nozzle

If the steam nozzle is blocked or clogged, it can trigger the 6E error code. Debris or mineral buildup can obstruct the steam nozzle.

Solution

Unplug and Prep: Unplug the dishwasher or switch off the circuit breaker.

Remove Lower Rack: Take out the lower dish rack to get to the steam nozzle at the back of the tub.

Inspect Nozzle: Look for any gunk or mineral buildup on the nozzle. If you see white, chalky stuff or food bits, it’s probably clogged.

Clean Nozzle: Use small brush or toothpick to gently clear out any debris. Be gentle so you don’t damage the nozzle.

Deep Clean: If it’s really clogged, soak the nozzle in a mix of water and white vinegar for about 30 minutes. This helps dissolve the buildup. Rinse it well afterwards.

Reconnect: Plug the dishwasher back in or turn the circuit breaker back on.

Damaged steam solenoid

The steam solenoid is responsible for controlling the flow of steam into the dishwasher. If it is damaged or malfunctioning, it may cause the 6E error.

Solution

Let’s get that steam solenoid fixed up on our dishwasher.

Locate the steam solenoid near the bottom—look for the two wires connected to it.

  1. Disconnect the wires from the solenoid.
  2. Grab your multimeter and check for continuity across the solenoid terminals. We’re aiming for a reading around 1000-2000 ohms.
    • If the reading is open (OL), solenoid is defective and gotta be replaced.

If it tests bad, order a replacement part from an LG appliance parts retailer or directly from LG. Make sure you get the correct part number for our specific dishwasher model.

With the new solenoid in hand:

  1. Disconnect the water line from the old solenoid and remove it from the mounting bracket.
  2. Install the new solenoid and reconnect the water line.
  3. Reattach the wires to the new solenoid, ensuring the connections are secure.

Loose or disconnected wiring

Loose or disconnected wiring in the steam system can disrupt the communication between the steam sensor and the control board, resulting in the 6E error code.

Solution

let’s check the wiring, especially the connections on the steam sensor. Keep an eye out for any frays, burn spots, or loose connections. If you spot any loose connections, tighten them up. If you find any damaged wires, replace them.

If you think a specific wire might be causing the problem, you can test it individually.

Disconnect both ends of the wire and set your multimeter to continuity mode. 

Place one meter lead on one end of the wire and the other lead on the opposite end.

If the meter shows continuity (a closed circuit), then the wire is good. If not, there’s a break in the wire that needs fixing, or you might need to replace the wiring harness.

Once you’ve checked and tightened the wiring, reattach the toe panel.

Faulty control board

In some cases, the control board may be malfunctioning, leading to the 6E error code. The control board manages the overall operation of the dishwasher.

Solution

6E error code on your LG dishwasher, it might be a sign that the control board’s acting up.

Control board are like the brain of your dishwasher, handling everything, including the steam system. 

If it’s not working right, it can mess with the communication between the steam sensor and the board, causing that error to pop up.

What we can do:

  • Check the wiring: Make sure all the wiring connections between control board and other parts, like the steam sensor and steam solenoid, are tight and not damaged. Loose or disconnected wiring could be the culprit.
  • Reset the dishwasher: Simple reset can do wonders. Turn off the dishwasher using the power button or unplug it, wait a few minutes, then turn it back on.
  • Replace the control board: If the error code sticks around, we might need to replace the control board. This one’s a bit tricky and probably best left to a pro. A qualified appliance repair technician can dig deeper and see if we really need to swap out the control board.

Water pressure issues

If the water pressure is too low or there is a problem with the water supply, it can cause the steam system to malfunction and trigger the 6E error code.

Solution

You’re getting that pesky 6E error code on your LG dishwasher, huh? It’s usually a water pressure thing, so let’s check a few things together.

  • Water Pressure: Make sure your water pressure is between 20-120 PSI. If it’s too low, we might need to call a plumber.
  • Water Supply Line: Check the water supply line. Is it kinked or bent? Straighten that out because kinks can restrict water flow.
  • Frozen Pipes: If your dishwasher’s in a spot where it could get cold, maybe the water line’s frozen. Try thawing it out with a warm, damp towel.
  • Leveling: Your dishwasher needs to be level for best performance. Make sure it’s not tilted or uneven.
