What Does Error F03 Mean?

The Bauknecht washing machine error F03 indicates a malfunction related to the drain pump, preventing water from draining properly and often accompanied by unusual noises. This issue may stem from a blockage in the drainage system, a fault in the temperature or NTC sensor, or problems with the water-level sensing mechanism. To address this, users can perform basic checks for blockages, clean the drain pump filter, and reset the machine. If the error persists, further inspection by a technician may be necessary.

Common Symptoms:

  • Program stops early or mid-cycle
  • Water remains in the drum / machine unable to drain
