Try these first

Start here before buying a part or taking the appliance apart.

  1. 1
    Run Bosch’s power reset first

    Switch the washer off, disconnect power for at least 30 seconds, and reconnect. If F38 was a one-off electronics state, it clears here — no part needed.

  2. 2
    Check for moisture near the machine

    A short can be caused by moisture at a sensor connection. Look for leaks or dampness around and under the washer before assuming the sensor itself failed.

  3. 3
    Write down when F38 appears

    Note whether F38 shows at start (heating stage) or mid-cycle. Temperature-circuit faults usually announce themselves when heating is involved — useful detail for the servicer.

A quick explanation

What does F38 mean?

The likely failed component is the NTC sensor or its wiring, but a reset comes first and model compatibility must be confirmed before any part is ordered.

The answer you came for

How to fix Bosch washer error F38

Reset first. If F38 returns, the sensor circuit needs resistance testing — sensor replacement is a model-specific repair, so compatibility must be confirmed from the model number before ordering anything.

  1. 1

    Power reset

    Disconnect power for at least 30 seconds and reconnect, following Bosch’s documented fault-code procedure. Retry a short programme.

    What you should see: F38 clears if the cause was a one-off state; it returns if the sensor circuit is genuinely shorted.
  2. 2

    Rule out moisture and visible wiring damage

    With power off, look for water trails, damp insulation, or rubbed-through wiring visible around the machine. Fixing the moisture cause is part of the real repair.

    What you should see: You know whether water, wiring, or the sensor itself is the prime suspect.
  3. 3

    Confirm model compatibility before ordering

    NTC sensors differ by platform. If the reset fails and you plan to replace the sensor, match the part to your exact model number (plate inside the door or on the back). The listing below is a candidate, not a confirmed fit.

    What you should see: Any part ordered is verified against the model first.
  4. 4

    When to stop

    Sensor resistance testing and internal sensor replacement involve panels and wiring. If you are not equipped for live-circuit diagnosis, stop at the model check and book qualified service.

    What you should see: Electrical diagnosis goes to someone equipped for it.
If the code comes back

Do not keep replacing parts based only on the code. Repeat the safe checks above. If the fault remains, stop and arrange qualified service rather than ordering from the code alone.

What may be causing it?

  • Shorted NTC temperature sensor
  • Damaged wiring or insulation shorting the sensor circuit
  • Moisture at the sensor connection

These are possibilities to investigate, not proof that one part has failed.
