Bosch Dishwasher E01 / E0100 Error Code

Bosch identifies E01 and E0100 as a heat-pump motor circuit fault at the main control board. Bosch directs a single 30-second breaker reset and support if the code is not resolved.

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

What the appliance detected

Detected condition

The dishwasher reports a heat-pump motor circuit fault at the main control board.

What may contribute

Possible causes

  • The control system detected a fault in the heat-pump motor circuit.
  • An internal motor, control, connection, or wiring condition 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 E01 / E0100 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 infer that the heat pump or main board itself has failed from the display alone.

  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

  • E01 or E0100 remains or returns after the Bosch-directed reset.
  • The dishwasher stops heating, circulating, or completing cycles normally.
  • Any internal pump, board, connector, or wiring diagnosis is required.
