Upper Spray Arm

About This Part

# Upper Spray Arm If your Bosch or Siemens dishwasher isn't cleaning your dishes properly, the upper spray arm may have worn out or failed. Over time, these plastic components can become brittle, crack, or develop blockages that prevent water from reaching your crockery effectively. Replacing a faulty spray arm is one of the quickest ways to restore your dishwasher's cleaning performance. This genuine upper spray arm (OEM reference 00740990) is designed specifically for Bosch and Siemens models and fits perfectly into your existing setup. The good news is that installation is straightforward—it's one of the easiest dishwasher repairs you can tackle yourself. Most homeowners complete the job in just a few minutes without requiring any specialist tools. When you're ready to install, simply ensure the dishwasher is empty and remove the lower basket for access. The spray arm clicks into place securely, so there's no need to worry about it coming loose during operation. Before ordering, please verify your dishwasher's E-Nr model number on the appliance's rating plate to confirm this part is compatible with your machine.
