Using this Bosch drain sump bellows hose is straightforward. First, make sure your washing machine is unplugged and turned off. Then, carefully remove the old hose from the drum to the pump housing. Align the new hose correctly and connect it firmly to both the drum and the pump. Check that the drain tube outlet is properly attached too. When it comes to maintenance, it's a good idea to inspect the hose regularly for any signs of wear, like cracks or leaks. If you notice any issues, replace the hose promptly. Also, keep the hose clean by gently wiping it down every few months.
