Oven overheating error — temperature exceeded safe operating limit
The E010 error on the Bosch HGI8054UC indicates oven overheating error — temperature exceeded safe operating limit. This typically occurs due to oven temperature sensor failure causing runaway heating. A qualified technician can usually diagnose this in 10–15 min (allow 45 min cooling time first), but the steps below will help you understand the issue.
Safety Warning
This is a high-severity error. Unplug the appliance immediately and assess the situation before attempting any repair.
Safety Warning
This repair is recommended for certified technicians only. The diagnostic steps below can help you understand the issue before calling for service.
Common Causes of E010
- 1Oven temperature sensor failure causing runaway heating
- 2Cooling fan failure preventing heat from dissipating around components
- 3Control board relay stuck closed keeping heating elements on continuously
- 4Oven used at maximum temperature for extended period in a poorly ventilated space
How to Fix E010
- 1
Step 1
Shut the oven off immediately — pull the plug or trip the breaker if you have to
- 2
Step 2
Allow the oven to cool completely for at least 45 minutes with the door open
- 3

Ensure the kitchen is adequately ventilated — open windows and run the range hood fan
- 4
Step 4
Do not restart the oven until it has fully returned to room temperature
- 5
Step 5
After cooling, plug in and attempt a test bake at a moderate temperature such as 350°F
- 6
Step 6
If the oven overheats again or displays E010 before reaching the set temperature, call a technician immediately
Tools Needed
When to Call a Technician
Oven displays E010 again or exhibits runaway heating — the control board relay or temperature sensor needs emergency professional diagnosis
Frequently Asked Questions
Common questions about Bosch E010 error
Yes, take it seriously. E010 means the oven ran hotter than its rated safety limit, which can damage internal wiring, insulation, and nearby cabinetry. Turn the oven off immediately and do not use it again until a technician has found and fixed the cause. Treat this as urgent — a stuck relay can cause runaway heating.
If the E010 error occurs during normal cooking at moderate temperatures, a faulty temperature sensor is the most likely cause. A malfunctioning sensor can allow the heating element relay to stay closed, driving oven temperatures far beyond the set point. This is a control-side failure that requires a technician to diagnose safely.
