B20CS30SNS

Bosch B20CS30SNS

Most common issues on this model

  1. Split in the water line at the hinge, where it bends with every door swing
  2. Chute flap for the ice stuck open, frosting the housing of the dispenser
  3. A narrow freezer mistaken for a capacity problem

Side-by-side refrigerators have been a rarity in Bosch’s US range, and the B20CS30SNS was one of them. It is a 300 Series counter-depth model finished in stainless, 69 3/4 inches high with a 35 7/8 inch width. Bosch has discontinued it. The ice and water dispenser is built into the door.

That arrangement carries a specific weakness. The water line to the dispenser runs through the door hinge and bends each time the door swings, thousands of times over the years, until it eventually splits, normally at the top hinge where the bend is sharpest. A puddle at the base of the door is the usual sign. The repair is well defined.

Other items show up on visits. The ice chute flap can stick open and frost the dispenser housing; kept open, it lets warm moist air in and eventually jams the mechanism. And owners often mistake the narrow freezer compartment for a capacity problem when it is simply the shape of a side-by-side. We check the hinge line first, then the flap.

B20CS30SNSB20CS30SNS questions
Water is showing up at the foot of the refrigerator door. Where is it from?

When a refrigerator dispenses through the door, its supply line is routed through the hinge and bends whenever the door moves. A split at that spot is common, and fixing it is a defined job.

Does it matter if the ice flap will not close?

Yes. A flap that stays open admits warm, damp air, which builds frost around the chute mechanism until it seizes, so we advise having it looked at soon.

My freezer seems too small. Is something wrong?

Probably not. The freezer on a side-by-side is narrow by design, so bulky items do not fit, and owners sometimes read that as a capacity problem.
