What F11 Means
F11 on an older Bosch Evolution range is the stuck keypad code. The manual notes it can be produced simply by holding any control key down for more than thirty seconds, and adds a second and less obvious cause: the oven temperature sensor circuit developing a bleed or short to the chassis of the range can also present as F11. That second possibility is why the manual gives a resistance test from each sensor wire to bare metal.
Common Causes of F11
- Control keypad stuck or shorted
- Object resting against the control panel holding a key down
- Temperature sensor circuit leaking to the range chassis
🔧 One Safe Check You Can Try
Disconnect power at the breaker for thirty seconds and restore it, and check that nothing has been leaning against the control panel. A cloth, a chopping board or a pan handle resting on a key produces this code with nothing broken.
⚠ Why You Shouldn't Go Further Than That
- The manual's second cause means a keypad code can actually be a sensor wiring fault, and replacing the keypad would not touch it.
- The test that separates them measures from the sensor wires to a ground point on the range, which needs the control module connector unplugged.
- On a dual fuel model the fascia sits above the gas manifold, so the appliance gas shut-off valve must be closed before working there.
- Keypads on this generation are bonded to the panel, so a replacement means the panel rather than just the membrane.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
