LG Washing Machine tCL Display

Last reviewed 11 November 2026 · Checked against LG's official support documentation and model manuals
tCL
Not an error — tCL is the Tub Clean reminder. LG's guidance: run the Tub Clean cycle on the empty tub, and clean monthly so the reminder — and the build-up behind it — does not keep returning.

Applies to front-load and top-load washers with a Tub Clean cycle.

What to check first

tCL is the washer asking for its own wash. Residue, moisture and detergent film build up in any machine that washes clothes but is never itself cleaned, and LG builds the reminder into the display: tCL appears when a Tub Clean cycle is due. LG's front-load list describes the response in one line — add the cleaner, select Tub Clean, run it on the empty tub — and adds that running it monthly keeps the reminder away.

Like CL, tCL is in LG's code list mainly so owners do not mistake it for a fault. There is nothing to repair here; there is a cycle to run.

Safety first

Common causes

The Tub Clean interval has come due

The reminder is scheduled by the machine's usage — it appears because the tub is due its clean, not because something has broken.

Build-up conditions inside the tub

The reason the reminder exists: residue and moisture accumulate in the drum, seals and sump over ordinary use. A monthly Tub Clean is LG's stated prevention.

Running the Tub Clean cycle

  1. Empty the tub completelyNo laundry, nothing left in the drum — the cycle cleans the machine, not a load.
  2. Add a powder washing-machine cleanerUse a powder washing-machine cleaner as LG directs — an oxygen-bleach formula is the type LG NZ recommends. Avoid chlorine-based or acidic cleaners.
  3. Select Tub Clean and let it finishRun the full Tub Clean cycle. When it completes, the reminder is answered — and LG's cadence is monthly from here, which prevents tCL from becoming a regular sight.

When to call a technician

A reminder that returns immediately after a properly run Tub Clean — right cleaner, full cycle, empty tub — is the one tCL case worth a service conversation, since the machine is then failing to register its own maintenance. Everything short of that is resolved by the cycle itself.

Model differences that matter

Machine typeWhat changes
Front loadtCL is on LG's front-load list: add powder cleaner, select Tub Clean, empty tub; monthly cleaning prevents recurrence.
Top loadThe same reminder and the same response on LG's top-load documentation (NZ): the reminder can be dismissed by selecting another cycle or pressing a button if a wash cannot wait — the clean still needs to happen.

Questions people ask about tCL

Is tCL a fault?

No — it is a maintenance reminder, like CL it sits in LG's code list so it is not mistaken for an error. The correct response is a Tub Clean cycle, not a repair.

I need to wash now. Can I skip the reminder?

Yes — LG NZ's guidance is that the reminder can be dismissed by selecting another cycle or pressing a button. Run the Tub Clean as soon as the machine is free, though: dismissing the message does not dismiss the build-up.

Which cleaner should I use?

A powder washing-machine cleaner, per LG — with LG NZ specifying an oxygen-bleach type as the recommendation, and warning that chlorine-based or acidic cleaners may cause discoloration and rust inside the machine.
