Bosch range dE Status Message

Bosch identifies dE with non-heating cooking zones as Demo Mode, a configuration state rather than proof of a failed induction module.

Applies to Bosch induction slide-in range using dE for Demo Mode

What the appliance detected

Detected condition

Demo Mode is active, allowing controls to operate without normal cooking-zone heating.

What may contribute

Possible causes

  • Demo Mode may still be enabled from display, delivery, or setup.
  • The mode may have been enabled accidentally.
  • If dE clears but heating does not return, a separate operating or service issue may exist.

Start conservatively

Safe preliminary checks

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

  1. Confirm the exact dE display

    • Photograph dE and confirm the model is an applicable Bosch induction slide-in range.
    • Do not assume another D/E code means Demo Mode.

  2. Follow Bosch Demo Mode exit timing

    • Bosch directs owners to disconnect power at the breaker or fuse for 30 seconds and restore it.
    • Within the next three minutes, touch any appliance control as Bosch documents.

  3. Verify normal heating behavior

    • After dE clears, test only normal cookware operation according to the owner manual.
    • If heating does not return, stop repeating Demo Mode steps and troubleshoot the separate symptom.

Actions not recommended

  • Do not enter undocumented service menus or hidden setup modes.
  • Do not remove panels or test induction electronics because dE appears.
  • Do not repeatedly cycle power if Demo Mode clears but heating remains abnormal.

When to stop and request service

  • dE returns after the documented Demo Mode exit procedure.
  • Cooking zones still do not heat normally with suitable cookware after the mode clears.
  • Controls, induction electronics, or supply diagnosis beyond normal operation is required.
