Slow ice and a wet floor: the Sub-Zero faults we see most in Orinda kitchens

Across the mid-century homes around Orinda Way and the newer canyon builds toward Glorietta, two refrigeration complaints come up far more than any other: ice that comes slowly or hollow, and a thin film of water that keeps reappearing under the freezer drawer.

Both sound alarming, and both are usually a small, well-defined part rather than the failure people fear.

Slow, small or hollow ice

When an ice maker slows down, the first suspect isn't the module — it's the water path feeding it. A fill valve that's weakening, or a supply line that's partly restricted, delivers too little water per cycle, so cubes come out small, hollow or sparse. We meter the fill valve and check the line pressure before touching the ice maker itself. Only when the water side checks out clean do we look at the module and its sensor. That order matters, because replacing a healthy ice maker never fixes a starving water supply.

Water pooling under the drawer

A recurring puddle at the bottom of the freezer is most often a blocked defrost drain. Every refrigerator melts a little frost on a schedule; that meltwater is supposed to run down a small drain and evaporate away. When that drain ices over or clogs, the water backs up and spills onto the freezer floor and out under the drawer. Clearing and flushing the drain path solves the common case. If it returns quickly, the defrost cycle itself or its heater needs a closer look — which is a metered diagnosis, not a guess.
