Bosch Range Error Code F125

F125 indicates that the voltage signal from the Cancel touch key on the control panel has gone outside of acceptable limits. The control board monitors this signal continuously and only triggers the fault after the condition persists for a full minute. This points to a problem with the Cancel key itself, the wiring between the panel and the board, or the control board.

An F125 fault related to the Cancel key circuit can affect your ability to cancel or stop cooking functions reliably. Until the fault is resolved, you may not be able to trust that the Cancel key will respond correctly in an emergency situation. It is advisable to resolve the fault before relying on the range for normal cooking, particularly for timed or unattended operations.

Repair costs vary depending on which component has failed. A touch key panel assembly replacement typically falls in the range of $80 to $200 for parts, while a main control board can cost $150 to $400 or more depending on the model. Adding professional labor will increase the total, generally by $100 to $200 depending on your area and the technician. If the fix is simply cleaning the panel or reseating a connector, you may have no parts cost at all.

Some causes of F125 are DIY-friendly. Start by cleaning the control panel surface to remove any moisture or grease that could be affecting the Cancel key signal, then power cycle the range to see if the error clears. If the issue persists, checking the ribbon cable connection is a feasible next step for someone comfortable working with appliance electronics. Replacing the touch panel assembly or main control board typically requires more technical skill and the correct replacement parts.

A power cycle reset, done by turning off the circuit breaker for about 30 seconds and restoring power, may temporarily clear the F125 code. However, because the fault requires the out-of-range voltage to persist for one minute before triggering, if the underlying hardware issue remains, the code will return. A reset is a useful diagnostic step but not a permanent fix unless the root cause has been corrected.
