LG Washer CL Error Code: Meaning, Causes & Fix

Child Lock is ON — not an error. The control panel is locked on purpose.

CL means LG's Child Lock feature is active: the panel buttons are disabled (except Power on many models) so children can't change or start cycles. It is a status display, not a fault. CL gets mistaken for an error constantly — and on segmented displays it is also mistaken for LE (the motor code), which sends owners down a needless motor diagnosis. CL is the only entry in this guide where the correct repair is to do nothing to the machine at all. LG built Child Lock as a persistent safety state: it disables every control except Power, it can be set at any time including mid-cycle, it survives the end of the cycle, and it survives the power being turned off and on - LG states all of that explicitly, because a lock a power flicker could defeat would protect no one. The display supports it by alternating CL with the remaining time during a locked cycle and lighting the lock icon at power-on. Every CL puzzle — the dead panel, the code that will not clear, the lock nobody remembers setting — is explained by those persistence rules, and every genuine CL is released the same way it was set: powered on, the marked buttons held for a full 3 seconds, and a chime to confirm.

What causes the CL code on a LG washer?

Child Lock activated

Deliberately, or by a stray long press on the marked button pair.

Child Lock left on from a previous cycle, because it never releases itself

LG is explicit that Child Lock is not automatically disabled when a wash cycle ends — it stays set until someone toggles it off manually, and if the unit is powered on while Child Lock is enabled, the lock icon illuminates. That is why CL so often appears to arrive from nowhere at the start of a new laundry day: it was switched on during yesterday's cycle, the cycle finished normally, and the lock simply carried over to the next time the machine was switched on.

A mid-cycle press on the wrong part of the panel

Because Child Lock is armed by holding marked buttons for about 3 seconds, it can be set accidentally by the actions that happen around a running washer: a hand steadying itself on the panel, a child pressing the buttons, or a user wiping the control surface and dwelling on one spot. LG notes the lock can be set at any time, including during a cycle, which is why CL sometimes appears part-way through a wash that started unlocked, with the display then alternating between CL and the remaining time.

Checks to run before you replace anything

1. Look for the lock/child icon lit near the CL display.
2. Try a button: beeps with no response = lock active, machine healthy.
3. Confirm it is really CL before doing anything else: with Child Lock set, LG states that all buttons except the Power button do not operate, the lock or child icon is lit, and on a running cycle the display alternates between CL and the remaining wash time. A panel where every button is dead except Power, with that icon lit, is a locked panel — not a failed one — and no other diagnosis should start until it is unlocked.
4. Find your model's exact release by reading the panel graphics, not by guessing: LG prints the method on the machine itself — look for a lock symbol drawn between two buttons (those two are held together), a button with *Child Lock written beneath it (that single button is held), or a Steam button carrying the lock marking. LG's published model variations are: Temp plus Rinse held together, the Spin button held alone, the Steam button held alone, and on some models a pairing such as Delay End and Add Item.
5. Apply the hold correctly when CL will not clear: the machine must be powered on first — LG specifically warns the lock will not turn off if you attempt it with the machine off — then press and hold the correct button or pair for at least 3 seconds, without lifting early. A successful toggle sounds a chime, and the CL indication either appears (you have just locked it) or vanishes and is replaced by the normal cycle time (you have unlocked it).
6. Distinguish CL from its look-alikes on the display: CL is accompanied by the lock icon and a panel that ignores everything except Power. LE, the locked-motor fault, appears with a machine that attempted to turn the drum and failed, and no lock icon story; tCL is the Tub Clean reminder or cycle, a maintenance state rather than a panel lock; and a display that flashes CL only while a cycle runs, alternating with the countdown, is Child Lock reporting itself mid-cycle, not a separate fault appearing and disappearing.

How to fix lg washing machine error code cl?

1. Deactivate: hold the Child Lock button (or the two buttons marked with the lock icon — often Temp + Spin or the dedicated button) for about 3 seconds until CL disappears. The exact pairing is printed on your panel.
2. To release CL on the common panel layouts, with power on: if a lock symbol links two buttons, hold Temp and Rinse together for at least 3 seconds; if *Child Lock is printed under the Spin button, hold Spin alone for 3 seconds (this is also the WashTower washer method LG publishes); if the lock marking sits under Steam, hold Steam for 3 seconds. Wait for the chime and confirm the display returns to a cycle time before testing the buttons.
3. If you changed a setting is needed mid-cycle, follow LG's sequence rather than fighting the lock: deactivate Child Lock with the correct hold, make the change, and if you want the protection back, re-activate it the same way — LG notes that changing the programme while locked is done by releasing the lock first, then selecting the new programme and pressing Start/Pause again.
4. If CL genuinely will not clear after the correct, powered-on, full 3-second hold on the marked buttons, stop trying power tricks: LG states that turning the power off and on does not release Child Lock, so repeated unplugging cannot cure it. LG's direction when the Child Lock buttons are unresponsive is that this could signal a malfunction and to contact customer support — at that point it is a panel fault wearing a CL display, not a lock you have failed to find.

The part that usually fails: None

CL is a feature state. No part is involved.

How to reset / clear the CL code

Not applicable — unlocking restores the panel instantly.

LG's standard reset is a power cycle: press Power off, unplug the washer for about 5 minutes, then — with the machine still unplugged — press and hold the Start/Pause button for 5 seconds to drain residual charge from the board. Plug back in and run a test cycle. There is no hidden reset button on LG washers; any code that reappears after this procedure is an active fault the control is still detecting, not a glitch that needs a deeper reset.

Why does the CL code keep coming back?

If CL re-engages by itself, a sticking panel button is likely — clean around the buttons; persistent self-locking is a panel fault. CL that seems to engage by itself repeatedly deserves a closer look at how the panel is being touched rather than at the washer's electronics. Because arming takes only a sustained 3-second hold on marked buttons, leaning on the panel, wiping it down with a damp cloth, carrying laundry baskets against it, or a child's exploratory pressing can all set it without anyone deciding to. If it still self-engages with no plausible contact, a sticking or moisture-affected panel button is the realistic suspect — keep the panel dry, note whether it is always the same household moment (cleaning day is a classic), and if the Child Lock buttons themselves become unresponsive to the correct release hold, follow LG's direction and treat it as a malfunction for customer support rather than a lock problem.

How to stop CL coming back

• Child Lock activated: Deliberately, or by a stray long press on the marked button pair.
• Child Lock left on from a previous cycle, because it never releases itself: LG is explicit that Child Lock is not automatically disabled when a wash cycle ends — it stays set until someone toggles it off manually, and if the unit is powered on while Child Lock is enabled, the lock icon illuminates.

Retrieving stored fault codes on LG washers

LG front-loaders have a test mode used by technicians: with the machine off, a specific three-button combination (commonly Soil Level + Spin Speed + Power held in sequence on many models, and a button-pair hold on others) steps the machine through fill, wash, drain, spin and heater tests while the display shows stored error history. The exact combination differs by model year, so technicians read it from the service manual for the model; if you enter a mode where the tub starts filling or the motor jogs, that is the test mode working — press Power twice to exit.

Other LG washer error codes

See the full list on the LG Washer error codes hub.

Codes CL gets confused with

IE — Inlet error — the washer is not filling with water properly (Water Inlet Error). IE (also read as 1E on segmented displays — they are the same code) means the control called for water and the level did not rise as expected.

1E — Inlet error — the washer is not filling (1E is the segmented-display rendering of IE). 1E and IE are the same LG fault: the washer called for water and the fill did not register in time.

PF — Power failure — the washer lost power during a cycle (and is telling you so). PF is a notification, not a breakdown: the control detected that power was interrupted mid-cycle.

OE — Drain error — the washer is not draining (Output Error in LG's naming). OE means LG's control ran the drain pump and the water level did not fall in time.
