Bosch Range F30 Error Code

When a Bosch range displays F30, the control has registered open probe connection. That directs attention toward the electronic control path, but the exact model/E-Nr and symptom pattern are still needed before choosing a repair path.

Start with external observations and manufacturer-approved owner checks only. If the code persists, move to model-specific diagnosis rather than repeated resets or speculative part replacement.

At a glance

• Code: F30
• Appliance: Bosch Range
• Verified meaning: open probe connection
• Primary diagnostic direction: the electronic control path
• Service-area context: San Francisco; confirm coverage by ZIP code

What the warning means

The verified technical anchor for F30 is open probe connection. Preserve that meaning in the factual layer. The warning narrows the diagnostic path toward the electronic control path, while the exact model and symptom sequence determine how that information should be applied.

Symptoms worth recording

Before changing settings or cycling power, record the behavior you can see or hear:

• The control may receive an impossible or missing reading.
• Temperature or cycle behavior may become inconsistent.
• The appliance might stop a program as a protective response.
• The same code may reappear immediately after startup.

Possible causes

The source record supports considering the following possibilities without treating any single one as confirmed:

• A failed sensor or probe.
• Damaged sensor wiring.
• A loose or corroded connector.
• An electronic input fault on the control board.

First steps that stay outside the appliance

• Write down the full code and model number.
• Verify only external conditions that can affect the reading, such as a properly closed door or unobstructed user-accessible area.
• Avoid probe internal sensor circuits while the appliance is energized.

These checks are for information gathering only. Do not expose live wiring, bypass an interlock, defeat leak protection, open a sealed refrigeration circuit, or use undocumented service-mode procedures.

When to stop using the appliance

Stop for overheating, electrical damage, gas odor, or water near electrical parts; otherwise avoid repeated operation if the sensor is required for safe temperature control.

When diagnosis becomes the next step

The sensor, wiring, connector path, and control input must be tested against the documentation for the exact model before a part is selected. Do not choose the most expensive module from the code alone. The technician should verify the relevant circuit or mechanism before recommending a repair.

For a service request, include what the appliance was doing immediately before the warning and which safe checks were already completed.

Why the full Bosch model/E-Nr matters

Record the complete model/E-Nr with F30. That identifier helps separate platforms that may use different controls, sensors, or service logic.

Still seeing F30?

If F30 remains active or comes back, request Bosch range diagnosis for the San Francisco service area. Include the complete model/E-Nr, exact code, symptom summary, and ZIP code so service coverage can be confirmed.
