Bosch Range Error Code F170

F170 indicates that the Bosch range's control board detected a power failure event using a 2-millisecond fault detection window. This means the appliance sensed a brief interruption or drop in the incoming electrical supply. The range logs this fault and may disable operation until the error is addressed. The issue is most often related to the household power supply rather than an internal component failure.

It is not recommended to continue using the range while F170 is active. The fault indicates a detected power supply anomaly, and using the appliance before the cause is identified could pose an electrical risk or result in further damage to the control board. Clear the fault, monitor for recurrence, and have the power supply inspected before resuming normal use.

Repair costs depend on the root cause. If the issue is a loose terminal connection or a household breaker replacement, costs may range from around $50 to $200 including a service call. If the main control board needs to be replaced, total repair costs including parts and labor typically fall in the range of $300 to $600 or more, depending on the specific model and local labor rates.

In many cases, yes. Start by checking that the range's power cord or terminal block connections are secure and free of corrosion. Verify that the dedicated circuit breaker is not weak or tripping under load. If the error was caused by a one-time power flicker in your home, resetting the range may resolve it without any repairs. If the code returns repeatedly, a qualified technician should inspect the wiring and control board.

A reset, typically done by cutting power to the range at the breaker for several minutes and then restoring it, can clear the F170 code if the original power event was a one-time occurrence. However, if the underlying cause such as a loose connection, weak breaker, or unstable household voltage is still present, the fault will return. A reset alone is not a repair.
