It refused to run a steam cycle with a full tank. He asked when it had last been descaled before touching anything, which turned out to be never. Descaled properly, checked the pump, and it has behaved since.

Sub-Zero · Gloucester, Massachusetts
The most exposed condensers we service are in Gloucester. A Sub-Zero that has never had its upper grille cleared will fail here years before the same unit would inland, and the single most valuable thing an owner on this coast can do costs nothing.
The brand, in general
Sub-Zero splits its cooling into two independent sealed systems on most built-ins, which is why a unit can hold a perfect freezer and drift warm on the fresh food side at the same time. That symmetry is diagnostic: it tells you the compressor is fine and sends you to the evaporator, its fan, and the defrost circuit that serves that half. The 500 and 600 series are still everywhere in Boston kitchens, and parts for both remain available, which is the question most owners actually want answered before they spend anything.
Gloucester kitchens
The most exposed coastline we cover. Condensers here corrode faster than anywhere else on our list, and a unit that has never had its coil cleared will fail earlier than the same unit inland.

The fresh food half kept creeping up to the mid forties overnight while the freezer sat perfect. He explained there are two separate cooling systems in there and only one had failed. Evaporator fan and defrost heater. Half the repair I was braced for.

Standing water in the bottom after every cycle. Ours is behind a custom panel and I dreaded it coming out. He read the code, checked the sump, found a blockage rather than a failed pump, and the panel never moved.
