What is the capacity of the b26ft70sns?
The Bosch B26FT70SNS bottom-mount refrigerator has an approximate total capacity of 26 cu. ft. For the exact capacity and how it is allocated between the refrigerator and freezer compartments, we recommend confirming the specifications in the B26FT70SNS owner’s manual.
Capacity can vary slightly by configuration and how manufacturers report usable space. For the most accurate number for your refrigerator:
- Check the specifications section in the B26FT70SNS owner’s manual
- Look for a rating label inside the fresh food compartment (often on a side wall)
- Match the full model and index (for example, “/08”) when comparing specs
- Use the compartment layout diagrams to understand where volume is counted
Most 36-inch French door, bottom-mount refrigerators in this class split capacity between fresh food and freezer storage.
| Compartment | Typical share of total | What it means for storage |
|---|---|---|
| Refrigerator (fresh food) | ~70% to 80% | Most shelves, bins, and drawers are counted here |
| Freezer (bottom drawer) | ~20% to 30% | Drawer volume is smaller but deeper |
Knowing capacity helps you compare replacements, plan kitchen storage, and choose the right maintenance parts (like a water filter) without guessing. If you are also troubleshooting ice or water performance, the how to replace the water filter in a Bosch refrigerator guide pairs well with the model specs.

How to read Bosch fridge model number?
On your Bosch refrigerator, we read the model number from the rating plate label inside the fresh food (refrigerator) compartment; for model B26FT70SNS, it is located on the right-side interior wall. Record both the model number (E number) and the serial number (FD number) for parts and service.
Check these common label locations first (starting with the one Bosch specifies for this model family):
- Inside the refrigerator compartment on the right-side wall (rating plate)
- On the ceiling of the refrigerator compartment
- On an inside side wall of the refrigerator or freezer compartment
- Inside the door area near the crisper drawers (varies by configuration)
For diagrams and the exact label callouts for your unit, use the B26FT70SNS owner's manual.
Bosch commonly uses these identifiers on the rating plate:
| What you’ll see | What it means | When you need it |
|---|---|---|
| Model number (E number) | The exact model identifier | Ordering model-specific parts, checking fit |
| Serial number (FD number) | Production and unit identifier | Warranty and service history |
When you write down the information, we recommend:
- Copy the model number exactly as printed (letters and numbers)
- Copy the serial/FD number exactly as printed
- Take a clear photo of the rating plate before ordering
- Match parts to the full model number, not just the brand (Bosch)
- Use the manual to confirm component names and locations (for example, the water filter location)
Bosch makes multiple similar-looking bottom-mount refrigerators; the model (E number) is what ties your B26FT70SNS to the correct parts list, diagrams, and troubleshooting steps. Having the serial/FD number also speeds up service if you ever need support.

How do you reset the filter on a Bosch b26ft70sns?
To reset the water filter indicator on your Bosch B26FT70SNS, press and hold the Light/Filter button for 3 seconds after replacing the filter; the water filter symbol stops flashing when the reset is complete (see the B26FT70SNS owner's manual).
- Replace the filter cartridge first.
- Press and hold Light/Filter for 3 seconds.
- Confirm the water filter symbol stops flashing.
- Dispense water for several minutes after a filter change to clear air and improve taste.
- If the refrigerator was powered off, expect the filter symbol to be reset automatically when it turns off.
These are the most common causes on this Bosch bottom-mount refrigerator:
- The filter cartridge is old or clogged.
- The filter was replaced but the reset was not performed.
- Water pressure is low, which can reduce flow and affect dispenser performance.
- Air is trapped in the water line after the filter change.
| What you see | Most likely cause | What we recommend |
|---|---|---|
| Symbol flashes after 3-second reset | Reset did not register | Press and hold Light/Filter again for a full 3 seconds |
| Poor taste or odor | Filter needs flushing or replacement | Flush several minutes; replace if it persists |
| Low dispenser flow | Clogged filter or low water pressure | Replace filter; verify household water supply |
If you are replacing the cartridge, use the correct Bosch filter for this model: refrigerator water filter 11034152.
Resetting the indicator keeps the filter-life tracking accurate, which helps maintain water quality and supports normal ice maker and dispenser performance.

What is the most common problem with a Bosch fridge freezer?
Cooling complaints are the most common issue we see with Bosch fridge freezers like model B26FT70SNS: the refrigerator or freezer runs warm because airflow is restricted (blocked vents), the door is not sealing, or the cooling system components (evaporator fan or defrost system) are not doing their job. For model-specific checks and settings, use the B26FT70SNS owner’s manual.
- Ventilation openings blocked: make sure interior vents are not covered by food packages (blocked vents can make temperatures rise).
- Door not closing properly: check for bins or containers preventing closure; confirm gaskets are clean and seated.
- Temperature set too high: verify the setpoint was not accidentally changed.
- Doors opened too often: frequent openings can cause warm temps and longer run times.
- Dirty interior causing odor: odors are common when spills are missed or strong-smelling foods are uncovered.
- Evaporator fan not running: if you do not hear the fan when the compressor is running, the fridge may not circulate cold air; the refrigerator evaporator fan motor 00618893 is a common suspect.
| Symptom | Most likely cause | Best first step |
|---|---|---|
| Fridge warm, freezer OK | Airflow blocked or fan issue | Clear vents; listen for fan |
| Both sections warm | Power issue, settings, doors left open | Check power, setpoint, door closure |
| Frost buildup, weak airflow | Defrost or airflow problem | Clear vents; inspect for heavy frost |
| Bad smell | Food odors or dirty compartment | Clean interior; cover foods |
When airflow is blocked or the door does not seal, the refrigerator has to work harder, temperatures swing, and food quality drops faster. The manual also notes that blocked ventilation openings increase power consumption, so fixing airflow issues can reduce energy use.
