What Does Error Code CL Mean on a LG Washing Machine?

Child lock active — controls are locked, not an error.

CL is a status indicator, not a fault code. When Child Lock is active the control board deliberately ignores all panel input except the unlock combination, preventing children from altering a running cycle. The board displays CL to confirm the lock state. It differs from true error codes because no sensor or component failure is involved — the panel is simply electronically disabled until the correct button combo is held to clear it.

Models affected: Virtually all LG washers with a digital control panel, both front-load and top-load models (e.g. WM3900HWA, WM4000HBA, WM3400CW, WT7300CW, WM8100HVA, WM4500HBA, WT7900HBA), since the Child Lock feature is standard across the lineup.
What owners report: Owners commonly report seeing CL after unresponsive buttons and assume a breakdown, when the lock was usually toggled by accident during cleaning or by a curious child. Holding the lock-symbol combination for a few seconds typically clears it right away; if it returns immediately, a sticky button may be holding the combo down.

How to Fix LG Washing Machine Error Code CL

🔧 Easy DIY Est. time: 10–20 min
Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Deactivate Child Lock

    Press and hold the Child Lock button (or the two buttons marked with the lock symbol, often Temp + Options) for 3–5 seconds until CL disappears.

  2. 2

    Power cycle if unresponsive

    Unplug for 60 seconds and try the unlock combination again after the panel reboots.

  3. 3

    Check for a stuck button

    Press each panel button — any that feel sticky or don't click may be holding the lock combo; clean around the button or replace the panel if jammed.

How to Reset Error Code CL

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

Frequently Asked Questions

Can I keep using my LG Washing Machine when error CL appears? +
Usually yes — CL is a low-severity settings notice that rarely stops the washing machine from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes CL on a LG Washing Machine? +
Across reported LG washing machine repairs, the most frequent is child Lock toggled accidentally (85% of cases), stuck control panel button keeping the combo pressed (10%), then control board glitch latching the lock (5%). Check them in that order before replacing any parts.
CL keeps coming back after a reset — what should I check next? +
A reset only clears the stored CL fault; if it returns, the settings problem is still present. Move on to the physical checks — deactivate Child Lock, then power cycle if unresponsive — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix LG Washing Machine error CL? +
A DIY repair typically runs $0–$0 in parts, versus $0–$120 for a professional service call. Expect the work to take about 10–20 minutes.
Which LG Washing Machine models show error CL? +
CL is documented on Virtually all LG washers with a digital control panel, both front-load and top-load models (e.g. WM3900HWA, WM4000HBA, WM3400CW, WT7300CW, WM8100HVA, WM4500HBA, WT7900HBA), since the Child Lock feature is standard across the lineup.. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
