Bosch Dishwasher E25 / E-25 Error Code

Bosch says E25 indicates the drain pump is blocked or the drain-pump cover is loose or missing. Bosch notes that debris may be sharp and says to review the owner manual if needed.

Applies to Bosch dishwasher

What the appliance detected

Detected condition

The dishwasher reports that the drain pump is blocked or the pump cover is loose or missing.

What may contribute

Possible causes

  • The drain pump cover may be loose or missing.
  • Debris may be blocking the accessible pump area.
  • The drain hose or related drain path may also be restricted.

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

    • Disconnect power before working near standing water.
    • Check the pump cover only as described in the owner manual and use caution because debris may be sharp.
    • Remove only loose debris that can be reached safely under the documented filter/pump-cover procedure.

  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

  • E25 remains after documented pump-cover and visible debris checks.
  • The cover is missing, damaged, or cannot be reseated.
  • Pump, wiring, or internal diagnosis would be required.
