Does this guide apply to your appliance?

Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.

Model and family references in this record:

LG models equipped with ezDispenseLG models with an automatic detergent dispenser

Likely causes

  • The automatic detergent dispenser drawer is partly open or not fully inserted.
  • Hardened detergent, detergent buildup, or another obstruction is preventing the drawer from closing.
  • The dispenser reservoirs or covers were not reassembled correctly after the drawer was cleaned or removed.
  • The drawer-position sensor, latch, or dispenser assembly may require service if the code remains after the drawer is correctly installed.

What to try

Fully close the detergent dispenser drawer

Easy
  1. Stop the washer.
  2. Push the automatic detergent dispenser drawer fully into the washer until it is properly closed.
  3. Restart the washer and check whether OPn has cleared.

Check for residue or incorrect dispenser assembly

Moderate
  1. Stop the washer and open the dispenser only when the washer is not operating.
  2. Inspect the drawer and compartment for hardened detergent, buildup, or another obstruction.
  3. If the drawer was removed or cleaned, verify that the detergent reservoirs and covers are correctly assembled.
  4. Slide the drawer slowly and fully back into place; do not force it.
  5. Restart the washer and check the display.

This step is marked caution. Stop if you are not qualified to continue.

Request service if OPn persists

Professional

This is a service referral, not a do-it-yourself repair procedure.

  1. Confirm that the drawer is fully inserted and that no visible obstruction remains.
  2. Do not continue removing or forcing the drawer while the washer is operating.
  3. Contact LG or a qualified appliance technician for model-specific diagnosis.
  4. Tell the technician that OPn remains despite the drawer being correctly closed; the drawer sensor, latch, or dispenser assembly may need inspection.

This step is marked professional. Stop if you are not qualified to continue.

The code returned or the check did not help?

Avoid repeated resets and do not select a replacement part from the code alone. Record the exact code, full model number, when it appeared, and the checks you tried with their results. Share these details with the manufacturer or service technician.

Disconnecting power does not establish that internal components are safe to touch. This guide does not authorize opening electrical components or bypassing safety devices.
