Aftermarket Water Pump Assembly — Hoshizaki S-0730 Reference

This aftermarket water pump assembly is offered against the Hoshizaki S-0730 replacement reference for commercial ice-machine service. Internal SKU: S0730. The existing catalog identifies the stocked item as non-OEM; its actual manufacturer and exact model compatibility still require confirmation.

Manufacturer number update

Hoshizaki service bulletin SB25-0010, dated July 25, 2025, replaces the legacy S-0730 reference with SP-0730 for the manufacturer pump kit. It describes a capacitor, instructions and conversion label in that kit. Do not assume those items are included with this aftermarket listing.

Function and service symptoms

The pump moves water through the ice machine's water circuit. Weak or uneven circulation, unusual noise, leakage or visible housing damage warrant inspection. These symptoms can also result from scale, restrictions, low water level, wiring or controls; they do not diagnose a failed pump by themselves.

Commercial applications

For technicians and facilities teams servicing compatible commercial ice equipment in restaurants, bars and foodservice facilities. A similar appearance or a broad series name does not establish fit.

Before You Order

• Record the complete machine model, serial number and auxiliary code.
• Match the current manufacturer parts list and the original pump markings.
• Compare electrical ratings, connectors, mounting points, orientation and water connections.
• Confirm the supplied manufacturer, replacement classification and included components.
• Have a qualified technician confirm the diagnosis and applicable installation instructions.

The existing listing identifies the stocked item as a non-OEM aftermarket replacement. The Hoshizaki number is a replacement reference; it does not establish who manufactured this item. Confirm the supplied brand and markings before ordering.

What happened to the S-0730 part number?

Hoshizaki bulletin SB25-0010 says its S-0730 pump was updated to the SP-0730 kit beginning July 2025. The manufacturer kit includes a capacitor, installation instructions and a conversion label.

Does this item include the SP-0730 kit contents?

Those contents belong to the manufacturer bulletin. The contents of this stocked replacement have not been independently established; confirm them before purchase.

Does it fit every KM-series ice machine?

No blanket KM-series compatibility is established here. Match the complete model, serial number, auxiliary code and current manufacturer parts list.

Does weak circulation always mean the pump has failed?

No. Water level, restrictions, scale, connections and controls can also affect circulation. Diagnose the water circuit before replacing a component.
