Jackson WWS, Hoshizaki Alliance since 2013
Jackson Warewashing Systems started as Otto Jackson's shop in Cleveland, Ohio in 1925, that's a full century of commercial ware-washing manufacturing as of this year. Ecolab bought the brand in 1994 and for nearly 20 years every Jackson door machine that shipped had an Ecolab chemical dispenser integrated into the frame. Hoshizaki USA Holdings acquired Jackson from Ecolab in 2013, and that's the ownership we work with today. The acquisition matters in the field for a specific reason: Jackson parts flow through the Hoshizaki California warehouse, and our techs service Jackson, Hoshizaki ice, Hoshizaki reach-ins, Lancer beverage, and Fogel refrigeration with the same parts account and the same dispatch logistics.
That's what the Hoshizaki Alliance actually is, not a marketing badge. It's an operational parts supply chain and service network spanning five foodservice categories. For a hotel kitchen with a Jackson RackStar conveyor in the dish room, two Hoshizaki KM ice machines behind the bar, and a Hoshizaki reach-in on the line, the Alliance means one service call resolves three pieces of equipment. No LA competitor writes this narrative because no LA competitor services all five Alliance brands from the same parts account.
Jackson is also the rare commercial dishwasher brand with a credible California parts story. Hobart ships most parts from the Troy, Ohio plant, 5 to 10 business days to LA. Champion and CMA ship from Winston-Salem, North Carolina, similar timeline. Jackson ships common parts out of the Hoshizaki Peachtree City, Georgia warehouse via the California regional, and that's usually a 1-to-3-day turnaround for LA. When a RackStar conveyor goes down on a Friday, the ship date is the story.
Jackson dishwashers and glasswashers we service
DishStar, entry door
DishStar HT (high-temp) and LT (low-temp) door machines, the entry tier, typical in small LA restaurants, coffee shops, and catering prep kitchens. Single-tank, manual-advance hood or door, Clean The First Time® delay-release door. Parts: wash pump, fill solenoid, thermostat, door latch, wash and rinse arm bearings.
TempStar, mid-range door
TempStar HH (high-hood) and LT single-tank door machines. Workhorse of mid-volume LA operations. Common parts: wash pump rebuild, fill valve, rinse booster element, door gasket, drain pump. Also the single most common Jackson model we service in the LAUSD school district cafeteria system.
DynaStar, premium door
DynaStar 10-AP and 12-AP premium door machines, fine dining and upscale hotel banquet standard. Heavier pump, smarter controls, extended-service components. Drier wares via hot-water final rinse at 180°F booster. Common service: booster element, control board, rinse solenoid, heat exchanger.
RackStar, WISR conveyor
Rack-conveyor with WISR (Water Intelligent Sensor Recycle), 0.38 gal/rack industry record. The one at every high-volume LAUSD cafeteria, UCLA dining commons, and big-hotel banquet prep kitchen. Service focus: WISR sensor calibration, pump chamber seals, curtain replacement, booster module.
AJ / AJX, large conveyor
Large-format rack conveyors, institutional cafeteria scale. AJ-66CE + AJX-66 configurations are common in hospital cafeterias (Cedars-Sinai, UCLA Medical, Kaiser), convention prep kitchens, and stadium commissaries. Service complexity is higher, multiple pump tanks, longer conveyor drives.
FlightStar, 29" flight-type
Flight-type with 29-inch belt for high-throughput kitchens, hotel banquet prep, stadium concession commissaries, airline catering. Continuous belt conveyance of dishes across pre-wash, wash, and final rinse zones. We service the belt, drive motor, pre-wash manifold, and spray-arm rebuild.
AvengerLT, low-temp undercounter
Low-temp chemical-sanitizing undercounter, bar-glass and small-ware. Common in WeHo craft-cocktail bars, Arts District taprooms, nightclubs where high-temp isn't wanted near the guest. Chemistry-balance service predominates, rinse-aid, sanitizer pickup, detergent feeder calibration.
JP-24, classic undercounter
High-temp undercounter, 24-rack-per-hour, restaurant bar and small prep stations. Long service life (we see 15-to-20-year JP-24s still running in LA). Service focus: wash pump rebuild, door gasket, thermostat, fill timer. Parts chain is strong, JP-24 remains a current production line.
WISR, why 0.38 gal/rack matters in LA
Water Intelligent Sensor Recycle is Jackson's proprietary water-conservation system on the RackStar line. The sensor detects whether a rack is fully loaded or partially loaded and adjusts the final-rinse volume accordingly. At 0.38 gallons per rack on full-load cycles, it's the industry record for rack-conveyor water consumption. For context, a typical rack conveyor without this technology consumes 0.75–0.90 gallons per rack.
In LA, where LADWP water rates keep rising and restaurant operators are watching the sewer-surcharge line on every bill, WISR is one of the real utility-economics features on any commercial dishwasher. When the sensor drifts, which it does in LA's hard-water environment as scale builds up on the sensor housing , the unit defaults to maximum rinse volume, and you lose the water savings. We calibrate and clean the WISR sensor as part of any RackStar service, same way we descale a Manitowoc ice machine.
Jackson was also ENERGY STAR Partner of the Year in 2024, the second time in four years. That matters for LA operators pulling California Energy Commission rebates on ENERGY STAR commercial dishwashers; the rebate check is real and the Jackson product family qualifies across the RackStar, DynaStar, and upper-tier DishStar/TempStar lines.
Jackson glasswashers in the LA bar cluster
West Hollywood, Arts District, Silver Lake, DTLA hotel bar programs, Santa Monica beach-adjacent speakeasies, Jackson glasswashers are thick on the ground in the LA craft-cocktail corridor. The reason is chemistry and glass clarity. Jackson's low-temp chemical-sanitizing glasswasher line (AvengerLT family plus the smaller JPX glasswasher) gives bartenders clear, polish-free glassware ready for service without the thermal stress of high-temp sanitizing rinses that can micro-craze crystal-style cocktail glasses.
Our typical bar-glasswasher call is chemistry, detergent dosing drift, rinse-aid pickup clog, sanitizer proportioning pump stall. Not usually a mechanical breakdown. We carry the common dosing-pump rebuild kits and rinse-aid pickup strainers for Jackson glasswashers on the truck. A typical bar glasswasher call is a 30-minute chemistry rebalance plus a 15-minute mechanical inspection, under an hour of truck time, and the bar is back to guest-ready glassware.
K-12, UCLA, LAUSD, Jackson's institutional cluster in LA
Jackson has a dedicated K-12 Education Sector program with extended parts and labor warranty beyond the standard commercial warranty. The premise is that school cafeteria dishwashers run hard during the academic year and need faster turnaround and longer coverage than a typical commercial install. In LA, that means LAUSD facility kitchens, UCLA dining commons (De Neve, Bruin Plate, Epicuria), USC University Village dining, CSULA, CSULB, CSUN, and the community college district.
We work the authorized Jackson service channel for K-12 warranty claims. For out-of-warranty work at institutional sites, we follow facility-department service protocols, including documented maintenance records for HACCP compliance and equipment-replacement-reserve reporting. K-12 cafeterias also get priority dispatch in our commercial queue because the service clock is hard, dishwasher needs to be running before the next meal period, and meal periods aren't negotiable.
Jackson + Ecolab legacy installs, the 1994–2013 specialty
From 1994 to 2013, Ecolab owned Jackson WWS, and during that window every Jackson commercial dishwasher that shipped had an Ecolab chemical dispenser integrated into the frame. LA has a lot of 15-to-25-year-old Jackson units still running in long-tenure restaurants, older hotel prep kitchens, and institutional facilities that don't replace dishwashers until they literally can't be repaired. Those units still have the original Ecolab-era wiring, dispenser system, and relay logic.
Finding a tech who understands Ecolab-era Jackson wiring is getting rare in LA. We've been servicing these units since the early 2000s and our guys know the Ecolab-era diagnostic flow, pickup tube strainer clogs, chemical-proof relay aging, proportioning valve drift. The usual misdiagnosis we clean up after other techs is "control board" replacement when the actual failure is a $30 pickup-tube strainer or a $70 proportioning valve. Same symptom, entirely different fix, and a couple-grand difference in the invoice.

Jackson dishwasher repair, frequently asked
Is Jackson owned by Hoshizaki?
Yes, Hoshizaki USA Holdings has owned Jackson WWS since 2013. Before that, Ecolab owned Jackson from 1994 to 2013; before that, the brand goes back to Otto Jackson's shop in Cleveland, Ohio in 1925. That 2013 acquisition is why you'll see Jackson parts coming out of the Hoshizaki California warehouse instead of Kentucky plant direct, and why we can service a Jackson dishwasher alongside a Hoshizaki ice machine and a Hoshizaki reach-in on the same visit. The Alliance isn't marketing, it's operational parts and service infrastructure our techs use every week in LA.
What's the Hoshizaki Alliance package advantage for LA restaurants?
Hoshizaki Alliance is a family of foodservice brands that share parts supply, service network, and extended warranty programs: Jackson (dishwashers + glasswashers), Hoshizaki (ice machines + reach-ins + sushi cases), Lancer (beverage dispensers), Fogel (refrigeration), and Structural Concepts (display cases, added to the Alliance in 2025). For an LA restaurant running Jackson ware-washing in the back plus a Hoshizaki ice machine behind the bar plus a Hoshizaki reach-in on the line, one call dispatches one service provider with parts for all three. California parts warehousing means 1–3 day turnaround on most components versus 5–10 days for Hobart from Ohio. That's a real operational gap our techs close every week.
What's the difference between Jackson DishStar, TempStar, DynaStar, and RackStar?
Four tiers matched to four different LA operation sizes. DishStar is the entry-level undercounter and door-type, the one in the small neighborhood restaurant, the coffee shop kitchen, the catering prep. TempStar is mid-range, single-tank door machines with Clean The First Time® delay-release doors, the workhorse of mid-volume LA restaurants. DynaStar is the premium door-type with extended-service components, heavier pump, smarter controls, fine dining and upscale hotel banquet. RackStar is the rack-conveyor line with WISR (Water Intelligent Sensor Recycle), 0.38 gallons per rack, which is the industry record. RackStar goes into high-volume institutional cafeterias, hotel banquet prep, and large-venue operations. Call out your model number when you call, the service path is different for each family.
Do you service Jackson glasswashers at LA bars?
Yes, Jackson glasswashers are thick on the ground in the WeHo craft-cocktail corridor, Arts District bars, DTLA hotel bar programs, and Santa Monica beach-adjacent spots. The typical Jackson bar-glasswasher issue isn't the machine, it's chemistry balance. Glass ware-washing at a bar uses low-temp chemical sanitizing rather than high-temp rinse, and when the detergent feeder, rinse-aid dispenser, or sanitizer pickup tube gets pinched, clogged, or miscalibrated, you get hazy glassware and bartenders polishing by hand. We diagnose the chemistry side alongside the mechanical side on every bar call. Most Jackson glasswasher complaints resolve with a 30-minute service plus a 10-minute chemistry calibration.
Can you troubleshoot old Jackson units with Ecolab chemical dispensers?
Yes, this is one of the places our techs earn our keep on older LA equipment. Ecolab owned Jackson from 1994 to 2013, and during that window Ecolab-integrated chemical dispenser systems were standard on every Jackson sold. LA has a lot of 15-to-25-year-old Jackson units still running with original Ecolab dispensers, the dispensers still work, but finding a tech who understands the Ecolab-era wiring logic is getting rare. We do. The usual Ecolab-era issue is pickup-tube strainer clogging or the chemical-proof relay aging out. Neither is a hard fix once you know the Ecolab-era wiring diagram.
Do you work with LAUSD schools on Jackson K-12 warranty?
Yes. Jackson has a dedicated K-12 education-sector program with extended parts and labor warranty above the standard Jackson commercial warranty, it recognizes that school cafeterias run hard during the academic year and need faster turnaround than the stated warranty envelope. We handle warranty claims through the Jackson authorized-service channel for LAUSD facilities, UCLA dining, USC dining, and the CSULA + CSULB + CSUN cafeteria systems. K-12 also gets priority dispatch in our queue because school kitchen failures have a hard clock, service needs to happen before the next meal period.
