Error Code E116

Oven Error Code E116: Core Temperature Sensor Connection Interrupted

Unfortunately, your oven is displaying error code E116. This code indicates a critical fault: the connection pathway between the oven’s main control board and the integrated core temperature sensor has been interrupted. This sensor is an important and specialized component crucial for accurately measuring the internal temperature of food during highly controlled cooking cycles, such as specific baking programs or steaming functions. When the connection is lost, the oven cannot verify precise temperature inputs, which causes the appliance to halt operation and display the error code.

What to do? Detailed Troubleshooting Steps

• Perform a Hard Reset of the Appliance. Sometimes, the E116 error is triggered by a temporary electrical glitch or a transient communication malfunction. To address this, completely switch off the oven, either by using the main electrical circuit breaker dedicated to the appliance or by carefully unplugging the oven from the wall socket. Leave the appliance completely disconnected from power for a minimum of 10 minutes. This waiting period allows the control board’s memory to clear fully. After 10 minutes, restore power and check if the error persists.

• Check the Plug and the Power Supply Connection. Verify the integrity of the oven’s electrical connection. Ensure the power cord plug is firmly seated and secure in the wall socket. Loose or intermittent power supply can sometimes cause momentary drops in voltage or signal integrity, which the control board may incorrectly log as a core sensor interruption. Ensure the power socket itself is functioning correctly.

• Inspect the Core Temperature Sensor for Visible Damage. If the sensor is externally accessible, inspect it carefully for any obvious signs of physical deterioration. Visible damage might include frayed wiring, bent connection pins, or melted plastic near the plug points.

  • Technical Warning: Checking the internal connection points or wiring of the sensor requires substantial technical knowledge and often necessitates partial disassembly of the appliance. Due to the inherent risk of electrical shock and the complexity of accessing internal components, it is strongly recommended that only qualified service professionals attempt this inspection.

• Contact an Authorized Service Center or Technician. If the E116 error persists after completing the reset procedure and verifying the power supply, a professional diagnosis is required. The interruption is likely due to a physical failure of the sensor component, damage to the internal wiring harness, or a fault on the main control board itself.

  • It is critical to have the oven checked and repaired by a professional certified to work on Bosch, Siemens, Neff, Constructa, or Gaggenau appliances.
  • Always clearly mention the specific error code, E116 (Core Temperature Sensor Connection Interrupted), when contacting service support. This information allows the technician to arrive with the appropriate diagnostic tools and potential replacement parts, helping to expedite the repair process.
