Safety Information
Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and injury to persons.
- Ensure the washing machine is properly grounded.

- Keep flammable materials away from the appliance.
- Do not operate the machine if it is damaged or malfunctioning.
- Unplug the appliance before cleaning or performing any maintenance.
Setup and Installation
1. Unpacking
Carefully remove all packaging materials. Inspect the machine for any damage incurred during transit. Remove all transit bolts from the rear of the machine before use. Failure to do so will cause severe vibration and damage.
2. Leveling the Appliance
Place the washing machine on a firm, level surface. Adjust the leveling feet at the bottom of the machine to ensure it is stable and does not wobble. Proper leveling reduces noise and vibration during operation.
3. Water Connection
Connect the water inlet hoses to the corresponding hot and cold water taps and to the machine's inlet valves. Ensure all connections are tight to prevent leaks.
4. Power Connection
Plug the power cord into a grounded electrical outlet (220V). Do not use extension cords or adapters.

3. Adding Detergent

4. Selecting a Wash Program
Turn the program selection knob to choose one of the 12 available wash programs. Common cycles include:
- Normal
- Heavy Duty
- Delicates
- Quick Wash
- Rinse
5. Special Features
- Wave Flume Technology: The crystal inner drum with 2196 water outlets and long-diameter 'S' type lifting paddles effectively increases contact area with clothes, dissolving stains and providing a more effective wash. The cold wash process, based on flow waves, achieves a standard 40°C cleaning effect without heating, saving up to 67% energy and protecting colors.
- Ultra Fine Bubbles (UFB): Nano bubble water enhances grease washing rate by 18% and reduces residue by 15%. Nano-sized bubbles penetrate fabric fibers to remove deep stains, bacteria, and residues, preventing yellowing and keeping fabrics fresh.
- Smart Control (T-Smart Life via Wi-Fi): Control your washing machine remotely using the dedicated T-Smart Life app on your mobile device, offering full control and enhanced convenience.
- Steam Wash: Before the main wash, a small amount of water is heated above 60°C to generate steam. This function raises the inner drum temperature and deeply penetrates fabric fibers, achieving 99.99% fabric sterilization and effective odor removal, while also reducing wrinkles.
- Origin Inverter Motor: The original inverter motor operates quietly (10% noise reduction), efficiently (up to 80% efficiency), and offers a durable lifespan of over 10 years. This results in energy savings of up to 67% and lower noise levels.
- Cyclone Mix Technology: An impeller in the detergent drawer increases the detergent dissolution rate by 20% and the washing rate by 10%, reducing detergent residue and saving time.
- Anti-Bacterial Gasket: The anti-bacterial gasket effectively prevents bacterial growth, ensuring a clean and hygienic wash every time.
- Drum Clean: This function activates a strong water flow through the gap between the inner and outer drums to remove odors and dirt, preventing secondary contamination of clothes. It also uses 90°C high-temperature sterilization for enhanced hygiene and extends the drum's lifespan.
6. Starting a Cycle
After selecting the program and any desired options, press the Start/Pause button to begin the wash cycle.
Maintenance
Regular maintenance ensures optimal performance and longevity of your washing machine.
1. Cleaning the Drum
Utilize the dedicated Drum Clean function periodically to remove residue and odors from the drum. This cycle uses high-temperature water to sterilize and clean the drum effectively.
2. Cleaning the Detergent Dispenser
Remove the detergent dispenser drawer and rinse it under running water to clear any detergent or softener buildup. Clean the housing of the dispenser with a brush if necessary.
3. Cleaning the Filter
Locate the drain pump filter, usually at the bottom front of the machine. Open the cover, drain any residual water, and carefully remove and clean the filter of lint and debris. Reinstall securely.
4. General Exterior Cleaning
Wipe the exterior of the washing machine with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
