Viking FNIU515D Nugget Ice Machine

Most common issues on this model

  1. Auger noise or slow nugget formation
  2. Ice output dropping
  3. Scale in the water path
  4. Water fill not completing

The FNIU515D is a current 5 Series 15-inch panel-ready nugget ice machine. The listing highlights restaurant-style nugget ice, high daily ice production, spacious storage and a Tru-Flush design.

Nugget ice depends on an auger, so an auger that grows noisy or slow is the first thing owners notice. Scale in the water path is the usual driver, because it narrows the passage and makes the auger work harder. We check the fill and the water filter, descale if we find buildup, and test the auger motor for speed and noise. The Tru-Flush design is about flushing the water system, so we also confirm the drain clears fully. A panel-ready door gets an alignment check.

Parts are normally easy to find for a model that is still sold. Our written price comes first, and a 30-day warranty follows.

FNIU515DFNIU515D questions
Why is my nugget ice machine louder than it was?

Scale or wear makes the auger work harder. We descale the water path, check the auger and motor, and replace worn parts rather than guessing.

What does the Tru-Flush design do?

It refers to how the water system flushes. If water lingers or the machine smells musty, we check that the flush completes and the drain clears.

Why is the ice softer or wetter than usual?

A slow drain or a warm condenser can leave the nuggets wet. We check the drain, the airflow around the machine and the water level in the reservoir.
