What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Diagnosis if the cleaning cycle fails
What they doIf Tub Clean stops with another code, the technician diagnoses that code (drain, water inlet, heating) using LG's procedure.
They must show youthe code that stopped the cycle and the check carried out.
In writingthe code, the cause found and the repair.
Full cleaning cycle after the repair
What they doAfter repairing, the technician runs Tub Clean and checks it finishes without codes.
They must show youthe Tub Clean cycle finished without a code.
In writingthe test and its result.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Empty drum before starting
- Who:
- you, no tools.
- How:
- remove all laundry from the drum. LG says the cleaning cycle runs without a load.
- Result that matters:
- an empty drum.
- If it is empty:
- move on to the cleaner.
- If laundry is left:
- remove it before starting the cycle.
- Evidence to keep:
- nothing special; note the cleaning date.

Suitable cleaner
- Who:
- you.
- How:
- use an oxygen-based washing machine cleaner at its maker's dose. LG advises against chlorine-based or acidic cleaners and warns that high-foam ones can cause leaks.
- Result that matters:
- a cleaner that matches what LG asks for.
- If it is oxygen-based:
- add it as the pack says.
- If it contains chlorine or is acidic:
- do not use it; it can discolour or corrode the tub.
- Evidence to keep:
- photo of the cleaner pack.

Full Tub Clean cycle
- Who:
- you.
- How:
- select Tub Clean (or Tub Sterilization) on the panel and press Start/Pause, as LG says.
- Result that matters:
- whether the cycle finishes and tCL stops appearing.
- If it finishes and the notice goes:
- done until the next 30 uses.
- If it stops with another code:
- deal with that code; if it does not clear, call service.
- Evidence to keep:
- photo of any code that appears during the cycle.

What it means
LG defines tCL as time to run the Tub Clean cycle. Its guide says to do it every 30 uses or when tCL appears, with an empty drum and an oxygen-based washing machine cleaner, and to avoid chlorine-based or acidic cleaners because they can discolour or corrode. The cycle holds the water at 60 °C. The notice comes from the board's usage counter, not a dirt sensor, so it does not indicate a fault. A technician is only needed if the cleaning cycle stops with another code.
