About This Part

# Bosch Dishwasher Fill Hose (12042721) If your Bosch dishwasher isn't filling with water or is leaking around the inlet area, a worn or damaged fill hose is likely the culprit. Over time, these hoses deteriorate due to water pressure, temperature fluctuations, and general wear, eventually causing performance issues or water damage beneath your appliance. The OEM reference 12042721 is a genuine Bosch replacement hose designed to restore reliable water supply to your dishwasher. Installation is straightforward, rated at difficulty level 2, making it an ideal DIY project for most homeowners. Simply turn off the water supply, disconnect the old hose from both the inlet valve and water tap connection, then reverse the process with your new part. A helpful tip: when reconnecting, ensure you hand-tighten the compression fittings firmly but don't over-tighten, as this can damage the threads. Use a small amount of plumber's tape on threaded connections for a watertight seal. This part suits various Bosch dishwasher models. Before ordering, please verify your appliance's E-Nr model number, which you'll find on the manufacturers label inside your machine, to confirm compatibility.
