Bosch Range Error Code F151

F151 indicates an EEPROM failure or a communication circuit failure between the display control board and the power board. The two main control boards in the range communicate through an 8-wire cable, and if that connection is broken or corrupted, the range will display this code. The fault can stem from a loose connector, a broken wire, or a failure within one of the boards themselves.

A reset by cutting power to the range for several minutes may temporarily clear the code, but it will return if the underlying fault is not corrected. If a wire is broken or a connector is loose, the communication failure will persist and the error will reappear during operation. A reset alone should not be considered a fix for F151.

Repair costs vary depending on the cause. If the fix involves reseating a connector or repairing a single wire, costs may be minimal, primarily covering a service call in the range of $75 to $150. If a display control board or power board requires replacement, parts and labor combined can range from $200 to $500 or more depending on the specific model and local labor rates.

Some cases of F151 can be resolved without professional help if the cause is simply a loose connector. Disconnecting the range from power, locating the 8-wire communication cable between the two boards, and reseating both connectors firmly may clear the code. If continuity testing reveals a broken wire or a board has failed, repair becomes more complex and may require a professional.

It is not recommended to continue using the range while F151 is active. The error indicates that the two main control boards cannot communicate reliably, which means the range may not be able to regulate burner or oven functions correctly. Operating the appliance in this state could pose a safety risk.
