How do I set up the washing machine for the first time?

Place the washing machine on a flat, stable surface, connect the water inlet hose to the water supply tap, ensure the drain hose is properly connected to a drainage system, and plug the power cord into a grounded electrical outlet. Then press the POWER button to turn it on, select your desired washing course, adjust water level and supply, add detergent to the detergent drawer, and press START/HOLD to begin.
