What Does Error 3 Mean?

The Blomberg washing machine error code 3 indicates a malfunction in the heating system, preventing the washer from heating water to the selected temperature. This often leads to prolonged wash cycles and ineffective cleaning due to the water not reaching the intended temperature. Key components that could be at fault include a faulty heating element or a defective temperature sensor.

Common Symptoms:

  • Cycle stops or delays during heating phase
  • Water does not reach the expected temperature
  • Longer wash times than normal

Possible Causes

  • Faulty heating element (medium)
  • Defective temperature sensor / thermostat (NTC) (medium)
  • Wiring or connection issue between heater components and control board (medium)

How to Fix Error 3

DIY Fix Basic checks before calling service

  1. Turn off the washer and unplug it from power.
  2. Check that the selected wash cycle includes heating.
