What Add means

On many LG dryer models, Add belongs to the water fill problem category. The appliance is not filling fast enough, cannot detect water, or sees an inlet fault.

Codes and exact steps can vary by model number, production year, and regional design. Use this guide as first-pass orientation and confirm model-specific details with the manufacturer source listed below.

Before you start

Write down the full model number and the exact display text before changing parts or clearing the control. Similar-looking codes can map to different model families, and a reset can erase useful timing clues.

If the appliance shows active leaking, a burning smell, smoke, gas odor, repeated breaker trips, or water near power, stop this checklist and use qualified service.

Common causes

  • Supply valves are partly closed
  • Inlet screens are clogged
  • Hose is kinked or frozen
  • Water pressure is below the model requirement
  • Inlet valve or flow sensor has failed

Recommended check order

  1. Confirm the model number and exact code spelling.
  2. Confirm hot and cold supply valves are fully open.
  3. Inspect fill hoses for kinks or crushing.
  4. Turn water off before removing hoses from the appliance.
  5. Clean inlet screens gently; do not remove screens permanently.
  6. Run one controlled reset only when the appliance is dry, stable, and safe.
  7. Stop if Add returns immediately or appears on an empty test.

Safe checks before service

  • Confirm hot and cold supply valves are fully open.
  • Inspect fill hoses for kinks or crushing.
  • Turn water off before removing hoses from the appliance.
  • Clean inlet screens gently; do not remove screens permanently.

What not to do

  • Do not bypass locks, sensors, fuses, or leak protection to force a cycle.
  • Do not open powered panels or touch wiring for a code check.
  • Do not assume one display code proves one specific part has failed.

Stop and call a technician when

  • The code returns with normal water pressure.
  • Water enters the machine while it is powered off.
  • The inlet valve buzzes but no water flows.

FAQ

Is Add always a broken part?

No. On a LG dryer, Add usually identifies a water fill problem category. A blocked hose, dirty filter, uneven load, or unsafe operating condition can trigger a code before a part failure is confirmed.

Can I reset Add?

A single power reset can be reasonable after visible checks are complete and the appliance is safe. If Add returns immediately, treat it as an active fault rather than a nuisance message.

Why does model number matter?

Brands reuse similar code text across model families. The model number controls the exact manual steps, access points, and service boundary.
