SR24C

Overview

The series is documented by Hobart's own replacement-parts catalog, Form 43078 Rev. A (August 2009), which covers the SR24C (ML-130021) and its companion SR24H (ML-130022). That catalog is the backbone of this page: it details the lower controls (previous and current construction), the electrical section, the door, the SR24C-specific lower fill, the upper fill and float assembly, and the wash-and-drain pump.

Used SR24C machines still circulate. A used-equipment listing groups an "SR24C, SR24H and WM5 dishwasher" (ref. 2204284-7-GO, listed at 24" x 20" x 34", classified under-counter), and McDougall Auctions' Saskatoon monthly restaurant sale offered a "Hobart SR24C Dishwasher & Bucket of Items" as unreserved Lot 6064. A related build, the SR24C-4, is listed as an undercounter chemical sanitizing dishwasher with a 16 5/8" door opening, a stainless steel lower front panel, automatic fill and pumped drain, and flexible fill and drain hoses supplied.

Key Features

• 14 racks per hour — the throughput figure published in a Canadian dealer listing for the SR24C.
• 2.4 gallons per rack — the water-consumption figure given alongside it.
• Undercounter, built-in format — classified as under-counter in used-equipment listings and as a built-in type in spec listings.
• Stainless steel — the listed color and finish.
• Digital, semi-integrated controls — the control type and control style stated in spec listings.
• 120-volt, single-phase power — as described for an SR24C at a Canadian restaurant auction.
• Deep factory parts coverage — Form 43078 Rev. A (August 2009) documents the machine down to shim washers, O-rings and lockwashers.

Control-side components listed for the SR24C include the electronic timer 00-892983 (1.08 lb, listed for the SR24C and SR24H), the wash thermometer 00-328695, and the red pilot light 00-813405, described with a heat-resistant housing for high-temperature commercial dishmachines.

Installation & Requirements

Hobart's published clearance and ventilation figures for this machine do not appear in the sources used here, so none are quoted. What the sources do establish is the connection hardware the factory catalogues for the SR24C.

Electrical

• An SR24C offered through a Saskatchewan restaurant auction is described as 120 volt, single phase.
• The parts catalog's motor-and-seal gasket assembly (00-328511) is referenced to 120/208-240/60/1 — 120 or 208–240 V, 60 Hz, single-phase builds across the series.

Water supply (fill side)

• Fill hose, 74 in. (00-293625)
• Pressure regulator, 1/2 in. (00-118038-00002)
• Strainer screen, 1/2 in. (00-270260) with gasket (00-270261) and branch plug (00-270259)
• Solenoid valve coil, 115 V (00-270380) and solenoid valve kit (00-270381)
• Flow valve (00-186864-00002), field-installed if required, with hose fitting (FP-081-15) and 1/2-to-3/8 pipe bushing (FP-027-10)
• SR24C-specific connection hardware: reducing washer, 3/4 in. to 1/2 in. (FE-007-23, qty 2) and restraint, 1/2 in. connection (FE-002-45)

Drain side

• Stand pipe, 20 1/2 in. long (00-185112) with metal pipe clamp (00-812621-00001) and steel spring clamp (00-113156-00001, CES-66)
• Bulkhead adapter (00-270478) with bulkhead adapter gasket (00-115840) and adapter nut (00-116198-00003)
• 1/4 in. O.D. tubing — 22 in. (previous construction) or 84 in. (current construction) — with plastic hose clamp (00-185111-00001)
• Drain channel, top half (00-115525)

PartHubz provides SR24-series installation, operation and parts documentation as resources alongside the parts it supplies.

Operation

Spec listings describe the SR24C's controls as digital, in a semi-integrated style. The parts catalog's lower-controls section — covering both previous and current construction — includes a Vari-Time module (previous construction), terminal blocks (00-294325-00010 and 00-294325-003-1), a marker strip (00-294326-00002), snap-in electrical bushings (FE-022-40) and a 2 1/4 in. rubber moulding (00-514410).

Components an operator interacts with or monitors include:

• Timer 00-892983 — an electronic timer, 1.08 lb, listed for the SR24C and SR24H.
• Wash thermometer 00-328695 — the wash thermometer for the SR24C/SR24H, listed at 3.3 in. high, 4.15 in. wide and 9 in. deep.
• Red pilot light 00-813405 — described as made specifically for the SR24C and SR24H, with a heat-resistant housing for high-temperature commercial dishmachines.
• Upper fill and float assembly — the catalog maintains a dedicated section for the float hardware on the fill side.
• Wash and drain pump — the catalog's wash-and-drain pump section lists the seal and drain impeller kit (00-435102) and the associated motor hardware.

Cleaning & Maintenance

The sources do not publish cleaning procedures or service intervals for the SR24C, so none are stated here. What Form 43078 Rev. A does establish is the replaceable hardware Hobart built the machine around:

• Seal and drain impeller kit 00-435102 — bundles the seal, drain impeller hardware, O-ring (00-067500-00030) and shim washers in 0.005, 0.015 and 0.030 in. thicknesses (quantities as required).
• Motor and seal gasket assembly 00-328511 (120/208-240/60/1) with motor mounting plate (00-436059), mounting-plate gasket (00-115716), seal ring (00-436106) and motor clamp assemblies (00-240106, qty 2).
• Fill-side renewal parts — 74 in. fill hose (00-293625), 1/2 in. strainer screen (00-270260) and 1/2 in. pressure regulator (00-118038-00002).
• Door hardware — the catalog's door section, plus the 2 1/4 in. rubber moulding (00-514410).
• Electrical renewal parts — terminal blocks, solderless lug (00-118544-00002), external shakeproof and helical lockwashers, and self-tapping screws.
• Stainless fasteners — the SST washer WS-017-21 is listed by parts dealers as fitting the SR24C, and also appears in the series catalog's hot water booster section.

Applications

An undercounter dishmachine rated at 14 racks per hour and 2.4 gallons per rack is aimed at kitchens that wash in low-to-moderate volume: bars, cafés, diners, small restaurants, staff cafeterias, and concession or institutional kitchens — anywhere the machine tucks beneath a counter rather than standing as a pass-through door machine. The 120-volt, single-phase service described for the SR24C suits buildings that do not carry three-phase power.

In Canada, SR24C units surface regularly on the secondary market: McDougall Auctions' Saskatoon monthly restaurant sale listed one with a bucket of items as unreserved Lot 6064, and used listings pair the SR24C with the SR24H and WM5. For machines already in service, PartHubz supplies the SR24-series replacement parts documented in Form 43078 Rev. A — from timers, wash thermometers and pilot lights to impeller kits, gaskets and fill hoses.
