How to Reinstall the Upper Feed Tube on Bosch Dishwashers

Bosch dishwashers have bottom and top spray arms that dispense water to the dishes on both racks during a cleaning cycle. These arms each have a feed tube that is connected to the pump motor within the bottom of the appliance. If the upper spray tube is leaking, remove the old tubing and install a new upper feed tube. Bosch sells some parts for its appliances online.
