What Does Error F01 Mean?

The Siemens Washing Machine F01 error indicates a malfunction in the heating subsystem, often due to a failed heating element or faulty temperature sensor. This error typically appears during heated wash cycles, causing the machine to stop mid-cycle or fail to reach the desired wash temperature. Addressing this issue may involve checking the heating element, temperature sensor, or control electronics.

Common Symptoms:

  • Error displays during a heated wash cycle before temperature is reached.
  • Machine stops mid‑cycle with F01/E01 shown; water may remain unheated. [家电配件与维修帮助](

Possible Causes

  • Heating element failure (no or slow water heating) (medium)
  • Faulty temperature sensor (NTC) or its wiring (medium)
  • Control electronics or heater relay fault (medium)

How to Fix Error F01

DIY Fix Preliminary user checks

  1. Cancel the current cycle and power off the washer.
  2. Run a wash without heating (e.g., cold wash) to confirm the machine otherwise operates normally.
  3. If comfortable, check that the door is closed properly (not specific to F01 but useful to ensure proper cycle start).

Technician Only Diagnostic and repair of heating subsystem

  1. Measure resistance of the heating element to confirm continuity and correct value.
  2. Measure temperature sensor (NTC) resistance at room temp to verify correct characteristic.
  3. Inspect wiring harness between heater, NTC, and control board for breaks/loose connectors.
  4. Check heater drive electronics (heater relay/triac) on the main control board and replace if faulty.

Parts needed: Heating element, Temperature sensor (NTC), Control board or heater relay/triac, Wiring harness/connectors

🛑 When to Call a Pro:
  • If the error returns after basic user checks or if heating subsystem diagnostics are beyond user capability.
  • If there’s any burning smell, visible electrical damage, or water leakage.
