The short answer
This page profiles the Bosch B-series freezer - the models whose number carries the B prefix - and routes you to the page for your fault. On this family the cabinet is built in flush with the run of units, it takes a trim kit or a custom panel, and it breathes through a grille in the cabinetry rather than from underneath. A freezer holds food safely at 0 F (-18 C) or below, and most faults here show up as that drifting.
Where each fault is answered
- The cabinet will not hold temperature — Airflow before refrigerant: the seal, the load, the vents and the grille come first. — Slug: bosch-bosch-freezer-b-freezer-cooling-failure-2 — Title: Bosch B-series freezer not keeping temperature: the order to check
- A new noise — Most of what this cabinet does is meant to be audible, so the first job is deciding whether there is a fault. — Slug: bosch-bosch-freezer-b-freezer-abnormal-noise-2 — Title: Bosch B-series freezer making a new noise: placing the sound
- Water inside or on the floor — Nearly always defrost water that did not reach its drain. — Slug: bosch-bosch-freezer-b-freezer-water-leak-2 — Title: Bosch B-series freezer leaking water: where it actually comes from
- A loud sizzle several times a day — The defrost heater clearing the evaporator, and it needs no attention.
Problem classes in order
- The cabinet will not hold temperature — Commonest here: this is airflow far more often than refrigerant, and all of that airflow is owner-controlled. No share is claimed for it.
- A new noise — Second here: a frost-free cabinet cracks and sizzles by design, so the first job is deciding whether there is a fault. No share is claimed for it.
- Water inside or on the floor — Least common of the set: the defrost cycle makes water on purpose, and a drain closing gradually is why it ends up elsewhere. No share is claimed for it.

Owner fix or service call
The door seal, the levelling, the load, the vents and the defrost drain are owner ground here. The line is the back panel: the fan, the defrost circuit and the sealed system need panels off, and refrigerant work is licensed.
