Bosch Range Error Code F120

F120 means the control panel has detected a touch key being held continuously for more than 60 seconds, which it treats as an error condition. This is most often caused by steam, grease, or soap residue on the touch surface rather than an actual hardware failure. The range triggers this code as a protective measure to prevent unintended operation from a false sustained input.

A reset may temporarily clear the F120 code, but if the underlying contamination is still present, the fault will return once the control panel is active again. Pressing CANCEL or cycling the power may clear the display, but a thorough cleaning of the touch surface is needed to prevent recurrence. Address the root cause first for a lasting fix.

If cleaning resolves the issue, there is no parts cost and you may avoid a service call entirely. If a touch control panel or control board replacement is needed, parts and labor costs typically range from $150 to $400 or more depending on the specific model and local labor rates. Getting a diagnostic assessment from a qualified technician before authorizing parts replacement is advisable.

In many cases, yes. Start by wiping down the touch control surface to remove any grease, soap, or moisture. If you can access the back side of the control glass, clean it with isopropyl alcohol to remove hidden contamination. Also make sure to redirect steam from cooking pots away from the control panel area, as condensation is a frequent trigger for this fault.

It is best to clear the fault before resuming normal use, as the error indicates the control panel is receiving an unintended sustained input. Continuing to operate the range with an active F120 code could result in unexpected behavior from the controls. The CANCEL key is specifically excluded from triggering this fault, so you can use it to attempt clearing the error.
