What Does Error F37 Mean?

The Bosch washing machine error F37 indicates a malfunction in the motor drive unit, specifically related to the temperature sensing system. This error typically arises when the water fails to heat to the set temperature due to issues with the NTC temperature sensor or its wiring. Users may notice that the wash cycle stops unexpectedly during heated programs, and the display shows F37 at this time. If the machine does not reach the selected temperature, further investigation is needed.

Common Symptoms:

  • Wash cycle stops unexpectedly when a heated program is selected
  • Display shows F37 during a heat‑involved part of the program
  • Machine fails to reach the selected water temperature

Possible Causes

  • Faulty temperature sensor (NTC) (medium)
  • Temperature sensor wiring/connectors issue (low)

How to Fix Error F37

DIY Fix Basic checks and reset

  1. Turn off and unplug the washing machine for 10–20 minutes to reset any transient control errors.
  2. Restart the machine and run the same program to see if the error returns.
  3. Ensure the selected wash program involves heating (F37 often appears with heated cycles).

Technician Only Inspect/replace temperature sensor and wiring

  1. Access the internal temperature sensor (NTC) on the heater assembly or drum housing.
  2. Test the resistance of the sensor at room temperature and compare with specification.
  3. Inspect wiring harness and connectors for damage or corrosion.
  4. Replace the temperature sensor and/or repair wiring if out of specification or faulty.

Parts needed: NTC temperature sensor, wiring harness/connectors

🛑 When to Call a Pro:
  • If the error persists after reset and basic checks.
  • If there are signs of burning smell, smoke, or other electrical faults.
  • If you are uncomfortable accessing internal electrical components.
