Bosch Range Error Code F124

CANCEL key pressed for more than 60 seconds

Bosch codesBosch range codes

CANCEL key pressed for more than 60 seconds — display control reacting to steam or soap build-up from cooking/cleaning on touch zones.

First step from the service manual

Customer education to direct excessive steam from pots away from touch areas. Clean excessive grease and grime build-up on touch surface areas. Use alcohol to clean contamination on back side of glass.

What F124 means on a Bosch range

The F124 error code on a Bosch range indicates that the CANCEL key on the touch control panel has been detected as continuously active for more than 60 seconds. The display control board interprets a prolonged signal from that key as a fault condition. Under normal operation, a brief press of the CANCEL key sends a momentary signal to the control. When that signal persists beyond 60 seconds, the control flags it as an error rather than a valid user input, and the F124 code is displayed.

The root cause is almost always environmental rather than a hardware failure. Steam rising from pots on the cooktop can condense on or behind the glass touch surface, temporarily altering the capacitance or conductivity in the touch zone associated with the CANCEL key. Similarly, grease, soap residue, or grime that accumulates on the front surface of the glass or on the back side of the glass panel can create a false continuous contact signal. The touch control system reads this contamination as a finger that never lifts off the key.

Because this code is triggered by external conditions rather than a failed component in most cases, the first corrective steps are cleaning and user habit changes. Alcohol-based cleaning of the back side of the glass removes conductive films that interfere with touch sensitivity. Directing steam away from the control panel during cooking prevents condensation buildup. If cleaning resolves the error, no parts replacement is needed. Persistent recurrence after thorough cleaning may point to a damaged touch glass or a failing display control board.

Common causes of F124

  1. 01

    Steam condensation on the touch surface

    Wiring / connection

    Steam rising from pots on the cooktop condenses on or behind the glass control panel, creating a false continuous signal on the CANCEL touch zone. This is most noticeable after boiling large volumes of liquid near the front burners.

  2. 02

    Grease or grime buildup on the touch glass

    Wiring / connection

    Accumulated cooking grease on the front surface of the touch panel can bridge the CANCEL zone and simulate a sustained press. Inspect the glass surface for visible film or residue directly over the CANCEL key area.

  3. 03

    Soap or cleaning residue on the glass

    Wiring / connection

    Residue left behind from cleaning sprays or soapy water can conduct enough current through the touch surface to trigger a false key press. Cleaning with isopropyl alcohol on both the front and back side of the glass typically resolves this.

  4. 04

    Conductive contamination on the back side of the glass

    Wiring / connection

    Moisture or residue that has worked its way behind the glass panel affects the touch sensor from the inside. Alcohol cleaning of the back surface is the recommended corrective step for this condition.

  5. 05

    Damaged touch glass or failing display control board

    Part replacement

    If thorough cleaning does not resolve F124 and the error returns consistently, the touch glass itself or the underlying display control board may be defective and sending a continuous key signal without any environmental trigger. Component replacement would be required in this scenario.

Frequently asked questions about F124

What does F124 mean on a Bosch range?
F124 means the display control has detected the CANCEL key as continuously active for more than 60 seconds. This is most commonly caused by steam, grease, or soap residue on the touch control panel rather than an actual hardware failure. The control interprets the contamination as a finger held on the CANCEL key without releasing it. Cleaning the touch surface and redirecting steam away from the panel resolves the error in most cases.
How do I fix the F124 error on my Bosch range?
Start by cleaning the touch panel surface thoroughly using isopropyl alcohol, including the back side of the glass if accessible. Remove any grease, soap film, or moisture from the CANCEL key area. Direct steam from boiling pots away from the control panel during cooking to prevent condensation buildup. If the error persists after cleaning, the touch glass or display control board may need to be inspected and possibly replaced.
Will resetting the range clear the F124 error?
A power reset by switching off the circuit breaker for a few minutes may temporarily clear the F124 code, but if the underlying contamination on the touch surface is not removed, the error will return. Cleaning the panel with alcohol is the necessary step to address the actual cause. A reset alone is not a lasting fix if moisture, grease, or residue remains on the touch zone.
Is it safe to use my Bosch range while F124 is displayed?
The F124 error indicates a control panel input issue rather than a gas, electrical, or heating system fault, so the range is not presenting an immediate safety hazard. However, with the CANCEL key registering a continuous signal, control behavior may be unpredictable. It is best to clean the panel and clear the error before resuming normal cooking use.
How much does it cost to repair an F124 error on a Bosch range?
In most F124 cases, there is no repair cost because the error is resolved through cleaning with isopropyl alcohol and adjusting cooking habits. If the touch glass or display control board is found to be defective after cleaning does not resolve the issue, parts and labor costs can vary, but board or glass replacements on Bosch ranges typically range from around $150 to $400 or more depending on the specific model and whether a technician is needed.
