Bosch Range Error Code E009

E009 on a Bosch range indicates a ROM-check error in the user interface control board. The range runs a memory integrity check each time it resets, and if that check fails, E009 is triggered. As a safety measure, all heating elements are immediately disabled until the fault is resolved. The user interface board will need to be replaced to clear the error.

No. When E009 is active, the range automatically disables all heating elements, so the cooktop and oven will not operate. The range is not safe or functional for cooking in this state. Do not attempt to bypass the error, and address the fault before resuming any cooking activity.

Repair costs for E009 will vary depending on the specific model and whether you use a professional technician or source the part yourself. User interface boards for Bosch ranges typically range from around 150 to 400 dollars for the part alone. Adding professional labor, total repair costs commonly fall in the range of 250 to 600 dollars. Getting a quote from a certified technician before proceeding is advisable.

A technician-level repair is recommended for E009. The fix requires replacing the user interface board, which involves working with electrical components inside the appliance. While a knowledgeable DIYer familiar with appliance disassembly may be able to perform the swap, it is important to disconnect power completely before starting and to handle the board carefully to avoid damage to connectors or surrounding components.

A power reset is unlikely to permanently clear E009 because the fault is caused by a hardware failure in the interface board's ROM. The ROM-check runs at every reset, so if the board's memory is corrupted or defective, the error will return each time the range powers on. A reset may temporarily clear the display in some cases, but the underlying fault requires board replacement.
