The Blomberg oven E1 error indicates a malfunction in the temperature sensor or its circuit. This can lead to inconsistent temperature readings, causing the oven to fail to heat properly or display erratic information during operation. When this error appears, it typically occurs at power-on or while initiating a heat cycle.
Common Symptoms:
- Error displayed at power‑on or when attempting to start a heat cycle
- Oven fails to heat or reaches correct temperature
- Temperature readings appear inconsistent or display resets
Possible Causes
- Faulty or open/shorted oven temperature sensor or its circuit (medium)
How to Fix Error E1
DIY Fix Basic Checks and Reset
- Turn off the oven and disconnect power at the mains for at least 5–10 minutes.
- Restore power and attempt a short heat cycle to see if the error returns.
Technician Only Inspect and Test Temperature Sensor and Circuit
- Disconnect oven from power (certified electrician/technician).
- Access the oven interior to locate the temperature sensor (usually at rear wall).
- Visually inspect sensor wiring and connector for damage or loose connection.
- Test sensor resistance with a multimeter at room temperature.
- Replace temperature sensor if open/shorted; repair wiring harness if damaged.
Parts needed: Oven temperature sensor (NTC/RTD), Wiring harness/connectors
- If error persists after basic reset and visual checks
- If internal components are inaccessible or damaged
- If multimeter tests indicate sensor circuit faults and replacement is required
