Buyer’s Guide: What to Look for in a Bosch Dishwasher Fill Valve

Before you order, here are the main things to check:

  • Model compatibility: Always verify your dishwasher model number (usually found inside the door frame) and cross-check with the valve’s compatibility list.
  • OEM vs aftermarket: OEM Bosch parts guarantee a perfect fit and long-term reliability. Aftermarket versions are cheaper but may not last as long.
  • Electrical connector type: Bosch dishwashers use specific wiring connectors. Ensure your replacement valve matches to avoid rewiring.
  • Water pressure tolerance: Choose valves designed to work with household water pressures (typically 20–120 psi). This prevents leaks or underfilling.
  • Warranty & returns: Genuine Bosch valves usually carry a manufacturer’s warranty, while aftermarket parts may have limited coverage.
