Is a noisy refrigerator a fault?

Often not. Defrost heaters tick, fans change speed and the sealed system makes gurgling sounds. A noise that is new and constant is the one to look at.

Do all of these models have an ice maker?

The table does not say, and this page will not guess. Look at the appliance: where there is no ice maker, the ice pages in this set simply do not apply to your model.

Can I keep using it while it waits for a visit?

If both compartments are at safe temperatures, yes. If either is not, move the perishables now and keep the doors shut, because every opening costs cold air you cannot replace.

What should I have ready before calling?

The full model number from the table, what each compartment actually measures with a separate thermometer, and how long it has been like that.

Which models does this family page cover?

Every model number in the table above, which all share the B prefix. Read yours off the inner wall rather than off a receipt before ordering anything.

Bosch B Refrigerator Problems

Table of Contents

What this family is

This is the profile page for the B family - the models listed in the table below. It says what the family is and routes each fault to the page that answers it.

What goes wrong on these models, and where each one is answered

A new noise: buzz, rattle, click or grind — A sound that is new rather than one that has always been there. See: Bosch B Refrigerator: Abnormal Noise or Vibration.
A compartment that is not holding its temperature — Warm fresh food, soft ice cream, or a unit that runs constantly without getting there. See: Bosch B Refrigerator: Not Cooling or Not Freezing.
No ice, slow ice, or ice that is hollow and small — An ice maker that has stopped filling, or cubes that never reach full size. See: Bosch B Refrigerator: Ice Maker Fault.
Water inside the cabinet, under a drawer or on the floor — A pool that returns after being wiped, or ice forming under the bottom drawer. See: Bosch B Refrigerator: Water Leak.

Problem classes in order on the B family

Water and leaks — First on the models below by call volume, because the defrost drain blocks predictably and the symptom is visible immediately. — Owner: Often yes
Cooling and temperature — Second, and the one that cannot wait: a compartment above what food safety needs is a deadline rather than an inconvenience. — Owner: Partly
Ice and water dispensing — Third. Almost always the supply side rather than the ice maker itself. — Owner: Partly

What is owner-fixable on these models

Drains, seals, levelling, airflow inside the cabinet and the water supply are owner work on these models. The sealed system is not, and never becomes so: refrigerant work is licensed work. Anything behind a fixed panel on the models below is a service call; everything reachable without a tool is yours.
