Bosch Refrigerator E02 Error Code

Bosch identifies E02 as an icemaker fault or an ice/water-system control communication issue. Bosch directs the owner to reset power at the breaker for 30 seconds and call support if the code is not resolved.

Applies to Bosch refrigerator with an applicable ice and water system

What the appliance detected

Detected condition

The refrigerator reports an icemaker fault or a communication issue involving the ice and water system controls.

What may contribute

Possible causes

  • The icemaker may have a fault.
  • The ice and water system controls may have a communication issue.

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 display and model

    • Photograph or write down E02 before clearing it.
    • Confirm the complete Bosch model number and owner manual because error displays and features vary by product family.

  2. Use the Bosch power reset

    • If you can safely identify the dedicated appliance breaker, switch it off for 30 seconds and then restore power as Bosch directs.
    • Avoid moving the refrigerator or reaching behind it solely to disconnect power.

  3. Protect food and stop at the service boundary

    • Keep refrigerator and freezer doors closed while checking whether normal cooling resumes.
    • If the code remains, returns, or cooling is affected, contact Bosch support or qualified service rather than opening internal electrical, ice-system, or refrigerant areas.

Actions not recommended

  • Do not assume the code applies to a different Bosch model without checking its manual.
  • Do not repeatedly cycle power or bypass controls.
  • Do not open internal electrical, dispenser, icemaker, sealed-system, or refrigerant components.

When to stop and request service

  • E02 remains or returns after the Bosch-directed 30-second power reset.
  • Ice or water functions remain unavailable.
  • Cooling, leaking, wiring, control, or internal icemaker diagnosis is required.
