Using this Bosch drain sump bellows hose is easy. First, make sure your washing machine is turned off and unplugged. Then, carefully remove the old hose from the drum and the pump housing. Next, attach the new hose firmly to both the drum and the pump housing, ensuring a tight fit. The drain tube outlet should be properly connected as well. When it comes to maintenance, it's a good idea to check the hose regularly for any signs of wear, like cracks or leaks. If you notice any issues, replace the hose right away. Also, keep the hose clean by gently wiping it with a damp cloth from time to time. And remember, if you're not sure whether this part is suitable for your washing machine, contact us with your full model number before you buy.
