What E116 Means
E116 concerns the meat probe socket. Bosch describes the mechanism as the hot wire shorting to ground, seen by the control as the probe connecting and disconnecting several times over. The probe is then disabled while the oven carries on working normally, and the fault clears when the control is reset. The suggested actions point at a loose connector shorting against cavity metal, and at dirty contacts inside the probe receptacle.
Common Causes of E116
- Dirty or carbonised contacts inside the probe receptacle
- Probe connector shorting against cavity metal
- Damaged probe lead making and breaking contact
🔧 One Safe Check You Can Try
Unplug the probe, look into the socket for food residue or carbon, and clean it gently when the oven is cold. Bosch lists a dirty contact within the probe receptacle as a cause, and that is the part of this you can reasonably reach.
⚠ Why You Shouldn't Go Further Than That
- The receptacle is mounted through the cavity wall, so anything beyond cleaning the visible contacts means working inside the oven liner.
- Bosch notes that the standard probe assembly is part of the control module on these ovens, so a receptacle fault can reach further than the socket itself.
- A connector shorting to cavity metal is not always visible, and chasing it with the oven assembled proves nothing.
- The socket sits in a heated cavity, so cleaning it while the oven is anything but cold risks a burn.
