Bosch Oven Error Code F153

F153 means the control calibration values stored in your oven's system are outside the acceptable operating range. This fault points to either a problem with the stored calibration data itself or a failure in the Power Board or Display Board that manages that data. The oven flags this code because it cannot reliably regulate temperature or operation without valid calibration references.

A power reset by turning off the circuit breaker for a few minutes may temporarily clear the code, but if the underlying calibration data is corrupted or a board component has failed, the error will return. A reset alone is not a fix. Recalibration or board replacement is needed to resolve the root cause.

If the issue is resolved through recalibration alone, the cost is minimal, typically limited to a service call fee ranging from around 80 to 150 dollars. If the Display Board or Power Board needs replacement, parts and labor combined can range from approximately 200 to 500 dollars or more depending on your specific model and local labor rates.

If the oven still allows access to its calibration settings, attempting a recalibration is a reasonable first step that requires no parts or special tools. If recalibration does not clear the fault, diagnosing and replacing the Display Board or Power Board involves working with high-voltage components and is best handled by a qualified technician. A knowledgeable DIYer comfortable with appliance electronics can perform board-level inspection and replacement safely if the oven is fully disconnected from power first.

Using the oven with an active F153 code is not recommended. Because this fault indicates the control system's calibration values are unreliable, the oven may not regulate temperature accurately, which could result in undercooked food or overheating. It is best to stop using the oven until the fault is diagnosed and resolved.
