What F10 Means
F10 is the runaway-temperature code on the older Bosch Evolution range platform with the ES337 control. The manual explains it appears when the control reads higher than normal resistance from the oven temperature sensor, which usually means the oven burner or element is not shutting off. It also documents a false version of the code that appears on a completely cold oven, where the cause is the sensor circuit or the control rather than real heat.
Common Causes of F10
- Oven burner or element not shutting off
- Oven temperature sensor reading higher resistance than normal
- Weak connection in the sensor harness plug producing a false code
🔧 One Safe Check You Can Try
If the oven is genuinely overheating, switch it off at the breaker and, on a gas or dual fuel model, close the appliance gas shut-off valve before anything else. If the oven is stone cold and shows F10, that is the false version the manual describes and it is not an emergency.
⚠ Why You Shouldn't Go Further Than That
- The manual notes that severe overheating may require the whole oven to be replaced if the damage is extensive, which is why this one is not worth testing by running it again.
- Bosch's own test is only conclusive while the F10 code is actually present, so a measurement taken after it clears proves nothing.
- On a dual fuel Evolution range the cooktop side is gas, so the appliance gas valve must be shut off before any work behind the fascia.
- The published resistance range for this sensor is narrow, and a reading taken without it cannot tell a good sensor from a failing control.
