This pump motor assembly replaces Hoshizaki part number HS-0178 (2A2848A01) on Hoshizaki KMD and KMS series cube ice machines. During the freeze cycle, the pump draws water from the sump and sends it through the water distribution system and over the evaporator plate, where layers freeze into cubes. The assembly runs on 120V, 60Hz power and mounts in the same location as the original pump.
A failing water pump usually shows up as low ice production, thin or cloudy cubes, or batches that never fully form. A noisy motor, a seized impeller, or a pump that hums without moving water are common signs of wear. Scale buildup, debris in the sump, and long run hours in high-volume service all shorten pump life. When the pump stops circulating water, the machine can’t make ice, so a quick replacement keeps the bar or kitchen supplied.
This assembly fits Hoshizaki KMD-700, KMD-850, KMD-900 and KMD-901 models in MAH, MRH and MWH configurations, plus the KMD-860MWJ and the KMS-822MLH and MLJ. Model fit can vary by serial number, so check the data plate on your machine before ordering. Disconnect power and water before servicing, and clean and sanitize the sump and water system when installing the new pump.
