What Does Error E101 Mean?
The Bosch oven error E101 indicates a malfunctioning temperature sensor, leading to erratic temperature readings and failure to heat. This error often occurs due to a fault in the temperature sensor circuit, including potential disconnection or failure, or communication issues with the control board. When this error is present, the cooling fan may run continuously, and the oven will fail to heat properly. Regular checks and replacement of the temperature sensor or control board may be necessary to resolve the issue.
Common Symptoms:
- Oven fails to heat
- Continuous operation of cooling fan
- Error appears on display at startup or during operation
Possible Causes
- Temperature sensor fault (disconnected, faulty, or incorrect resistance) (medium)
- Communication fault between temperature sensor and control board (medium)
- Control board fault after overheating or self-clean cycle (low)
How to Fix Error E101
DIY Fix Basic checks and reset
- Turn off oven power at circuit breaker for 5–10 minutes and restore to attempt reset.
- Listen for cooling fan operation when set to a bake temperature to check if fan spins.
- Visually inspect door and ventilation to ensure nothing is blocking cooling airflow.
Technician Only Diagnose and replace faulty components
- Disconnect power entirely and access the internal temperature sensor.
- Measure sensor resistance with a multimeter at room temperature and compare to expected ~1 kΩ value.
- Check wiring harness and connectors between sensor and control board for continuity and damage.
- If sensor is faulty replace it; if wiring is intact but error persists, test/replace control PCB.
Parts needed: Temperature sensor probe, Control board/PCB, Wiring harness/connectors
- If internal inspection reveals burnt, damaged, or corroded wiring or components.
- If sensor tests within expected resistance but error persists after reassembly.
- Whenever there is uncertainty about safely accessing internal components.
