Using this Bosch bellows hose is easy. First, make sure your washing machine is unplugged. Then, carefully remove the old hose from the drum and the pump housing. Next, connect the new hose in the same way. Ensure it's firmly attached to prevent leaks. When it comes to maintenance, check the hose regularly for any signs of wear and tear, like cracks or holes. If you notice any damage, replace the hose right away. Also, keep the hose clean by wiping it down occasionally. Remember, if you're not sure about the installation, it's best to get help from a professional. And always double - check the model compatibility before using the hose with your washing machine.
