Using this washing machine outlet hose is easy. First, make sure your washing machine is turned off and unplugged. Then, connect the 22mm or 34mm end of the hose to the appropriate outlet on your washing machine, depending on which one fits best. The other end should be connected to the drainage point. When using, ensure there are no kinks in the hose as this can block the water flow. As for maintenance, periodically check the hose for any signs of wear or damage, like cracks or leaks. If you notice any issues, replace the hose right away. Store the hose in a cool, dry place when not in use to extend its lifespan.
