Bosch Dishwasher E16 / E17 Error Code

Bosch says E16 and E17 indicate an issue with water flowing into the dishwasher or the filling system, and that water may not be able to enter the dishwasher.

Applies to Bosch dishwasher

What the appliance detected

Detected condition

The dishwasher reports a water-inflow or filling-system issue.

What may contribute

Possible causes

  • The inlet hose may be kinked or damaged.
  • The dishwasher may not be receiving water correctly.
  • A filling-system issue may require Bosch support.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the Bosch dishwasher display

    • Photograph or write down the exact code or flashing-light pattern before clearing it.
    • Confirm the full model number and owner manual because Bosch dishwasher codes vary by series and control platform.

  2. Use only documented homeowner checks

    • Check the visible inlet hose and make sure it is not kinked or damaged.
    • Confirm the water supply is on if the valve is safely accessible.
    • Do not pull the dishwasher out or disconnect water lines unless the model manual allows the step safely.

  3. Stop before internal dishwasher work

    • If the code remains or returns after documented checks, request Bosch support or qualified service.
    • Do not test live components, access control boards, bypass leak protection, or disassemble pumps or heaters beyond model-manual maintenance.

Actions not recommended

  • Do not reach into wet areas while the dishwasher has power.
  • Do not test live voltage or open internal electrical areas.
  • Do not treat an error code as proof that one specific internal component failed.

When to stop and request service

  • The code remains after visible hose and water-supply checks.
  • The inlet hose, connection, or surrounding area leaks.
  • Internal fill-system, valve, sensor, wiring, or control diagnosis would be needed.
