## How to Fix LG Error “tCL” (Tub Clean Indicator – Not a True Error Code)
The “tCL” message on your LG washing machine’s display is often mistaken for a serious malfunction. However, **”tCL” is an abbreviation for “Tub Clean”** and is a scheduled maintenance reminder, not a sign of a breakdown.
Your washer uses an internal counter to track the number of cycles you run. When it reaches approximately 30 cycles, the machine displays “tCL” to prompt you to run the **Tub Clean cycle** (also known as the “Hygienic Cleaning” or “Sanitize” cycle) to remove buildup, mold, and residue.

### Step-by-Step Fix: How to Diagnose and Resolve the “tCL” Reminder
Since “tCL” is a reminder, the solution is simply to run the designated maintenance cycle.
#### **Step 1: Obtain the Necessary Cleaner**
Before starting the cycle, you must use a proper tub cleaning agent. Do **NOT** use regular laundry detergent or bleach alone, as this can cause excessive sudsing or damage the drum.
* **Recommended Cleaner:** Use an LG-approved washing machine cleaner or a standard washing machine descaler tablet (like Affresh or a specialized LG Tub Cleaner Tablet).
#### **Step 2: Prepare the Machine**
1. **Empty the Drum:** Ensure the washer drum is completely empty of clothes.
2. **Add Cleaner:** Place the descaling tablet or cleaner (powder or liquid) directly into the main detergent dispenser, or directly into the empty drum, following the product’s instructions.
3. **Check Dispensers:** Ensure the bleach and softener dispensers are also empty.
#### **Step 3: Run the Tub Clean Cycle**
1. **Turn On:** Turn the machine on.
2. **Select Cycle:** Navigate through the cycle options until you find the **”Tub Clean”** (or “Hygienic Cleaning”) setting.
* *Note:* On some models, you may need to hold down a combination of buttons (like “Delay Wash” and “Soil Level”) simultaneously for 3 seconds to activate the cycle. Check your user manual if the cycle isn’t visible.
3. **Start:** Press the Start/Pause button.
The Tub Clean cycle uses very hot water and runs for a long duration (often 3 to 4 hours) to properly sterilize the drum.
#### **Step 4: Confirm Reset and Successful Completion**
Once the Tub Clean cycle has finished:
* **Check the Display:** The “tCL” message should disappear automatically, and the machine will revert to its normal ready state.
* **If “tCL” remains:** If the machine did not automatically reset the counter (this is rare), try unplugging the machine for 5 minutes (a hard reset). If the code still persists, repeat the Tub Clean cycle.
#### **Common Misdiagnosis and Likely Culprit**
While “tCL” is a maintenance prompt, the *effectiveness* of the cleaning cycle relies on the **Tub Cleaner Tablet**. If you run the cycle but use the wrong type of detergent or an expired tablet, the buildup might not be fully removed, which could potentially cause the sensor to signal the need for another clean prematurely (though the counter usually handles the reset).
**The most common mistake is ignoring the “tCL” reminder and continuing to use the machine without running the cleaning cycle.** This allows mold and residue to build up, leading to odors and eventually potential operational issues.
