What Does Error E101 Mean?

The Siemens Oven error code E101 indicates a malfunction primarily related to the temperature sensor, which may be caused by an open circuit, a broken sensor, or an implausible resistance reading. This error typically results in the oven shutting down or becoming unusable, preventing it from heating. Additionally, loose or corroded wiring to the temperature sensor could also trigger this error. If E101 appears, it’s crucial to address the sensor and wiring issues to restore normal operation.

Common Symptoms:

  • Oven shuts down or becomes unusable when E101 appears
  • Error appears on display and oven cannot start or heat

Possible Causes

  • Temperature sensor fault (open circuit, broken sensor, or implausible resistance reading) (medium)
  • Loose/corroded wiring or connector to the temperature sensor (medium)
  • Main control board fault (less common) (low)

How to Fix Error E101

DIY Fix Basic checks and reset

  1. Turn off and disconnect oven from mains power for 10–30 minutes
  2. Reconnect power and observe if E101 persists

Technician Only Inspect and replace temperature sensor and wiring

  1. Disconnect power and access oven temperature sensor (PT500/PT1000)
  2. Visually inspect sensor wiring and connector for damage, corrosion or breaks
  3. Measure sensor resistance with a multimeter at room temperature to confirm expected resistance value
  4. Replace defective sensor and repair damaged wiring if needed

Parts needed: Temperature sensor (PT500/PT1000), Sensor wiring harness and connector

Technician Only Control board inspection and possible replacement

  1. After verifying sensor and wiring integrity, test control board inputs related to sensor
  2. Replace control board if diagnostics indicate internal fault

Parts needed: Oven control board

🛑 When to Call a Pro:
  • If you are uncomfortable opening the oven and performing electrical tests
  • If replacing sensor and wiring does not clear the error
  • If control board diagnostics indicate deeper electronics fault
