Bosch Dishwasher E05 / E0106 Error Code

Bosch identifies E05 and E0106 as a wash-arm diverter circuit fault/error and directs a single 30-second breaker reset followed by support if unresolved.

Applies to Bosch dishwasher whose exact model documentation uses the listed display

What the appliance detected

Detected condition

The dishwasher reports a wash-arm diverter circuit fault at the main control board.

What may contribute

Possible causes

  • The control system detected an abnormal diverter-circuit condition.
  • The diverter, control, connection, or wiring may require professional diagnosis.

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 exact display and model

    • Photograph the display before clearing E05 / E0106 and confirm every character.
    • Confirm the full Bosch E-Nr / model number because codes and supported reset procedures can vary by series.

  2. Use only the Bosch-documented reset and exterior checks

    • If the appliance and breaker can be handled safely, switch the dishwasher circuit off for 30 seconds and restore power once, as Bosch directs for this code family.
    • Do not remove spray-system or sump components beyond normal owner maintenance to chase this electrical code.

  3. Stop at the service boundary

    • If the code remains or returns after the documented check, contact Bosch Customer Support or qualified appliance service.
    • Do not pull the dishwasher apart to reach pumps, heaters, control boards, sensors, wiring, or other internal components.

Actions not recommended

  • Do not test live voltage, remove electrical covers, or access the control board.
  • Do not bypass door, leak, heater, or other safety controls.
  • Do not replace a pump, heater, sensor, dispenser, wiring harness, or control board from the code alone.

When to stop and request service

  • E05 or E0106 remains or returns after the documented reset.
  • Water distribution or cleaning performance is abnormal.
  • Any diverter, board, connector, motor, or wiring diagnosis is required.
