The washing machine drain hose should be positioned at a height above the base of the washing machine, typically at a height of at least 3 inches (approximately 7.6 centimeters) and no more than 8 inches (approximately 20 centimeters) above the base. This positioning is essential to ensure proper drainage and prevent water from flowing back into the washing machine.
If the drain hose is placed too low, it may cause water to siphon back into the machine, leading to issues like flooding or inefficient draining. On the other hand, if the drain hose is positioned too high, it may cause the washing machine not to drain properly or result in water leakage.
Additionally, the drain hose should be properly secured to prevent it from coming loose or moving during the wash cycle. Make sure to follow the manufacturer's guidelines and local plumbing codes when installing or adjusting the washing machine drain hose.
