Using this Bosch bellows hose assembly 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 in the same way the old one was installed. Ensure all connections are tight to prevent leaks. When it comes to maintenance, regularly check the hose for any signs of wear, such as cracks or holes. If you notice any damage, replace the hose right away. As for the anti - syphon ball and pressure chamber, clean them occasionally to keep them working properly. And remember, if you're not sure about the installation or have any other questions, don't hesitate to contact us.
