What is the difference between an industrial and a commercial dishwasher?
Commercial usually means a door-type, undercounter, or glasswasher unit washing 30–80 racks an hour in a restaurant or bar. Industrial means a flight-type or rack-conveyor line, pot-and-pan machine, or tote washer running continuously at 150–350+ racks an hour in a hospital, school, stadium, or commissary — typically three-phase, with a dedicated booster and often a blower dryer. We service both; this page covers the high-volume side.
How much does industrial dishwasher repair cost in the Twin Cities?
Commercial diagnostic is $199 and is waived with any repair. Tank heater, level probe, and solenoid work lands $485–$985 all-in. Conveyor drive, pawl-bar, and curtain work runs $585–$1,650. Booster and blower-dryer repairs run $585–$1,450. Sealed or major control work is always quoted in writing before we start.
Can you work overnight or between meal periods?
Yes. Hospital tray lines, school kitchens, and banquet dish rooms are scheduled at night, before service, or during shutdown windows. We confirm the window in writing before dispatch so the machine is back in service before the next meal period.
Why does my final rinse fall below 180°F only during the rush?
That is a booster recovery problem, not a thermostat problem. At idle the booster holds temperature easily; at rack 40 it can't keep up if an element is weak, a contactor is pitted, the tank is scaled, or the building's incoming hot water is under 140°F. We test recovery under real throughput and correct the actual limiting factor.
Do you delime industrial machines on hard Twin Cities water?
Yes, and it is the single highest-return service on this equipment. Water here runs 12–17 grains hard, which scales manifolds, jets, elements, and boosters until cycle times stretch and capacity drops. We delime tanks, manifolds, and the booster in one visit and re-verify temperature and throughput afterward.
Do you service blower dryers and the conveyor drive together?
Yes. Blower-dryer motors, elements, filters, and air knives are tested on the same visit as the drive motor, pawl bar, and curtains, because wet ware at the exit is often a conveyor-speed problem rather than a dryer problem.
Are you certified to work on three-phase 480V equipment?
Yes. Our commercial technicians work 208/240V and 480V three-phase warewashing daily — megging elements, verifying phase balance under load, and replacing contactors and overloads. Building-side electrical beyond the machine disconnect is referred to a licensed electrical contractor.
Do you offer preventive maintenance for institutional dish rooms?
Yes. Quarterly and semi-annual plans priced by machine count include deliming, curtain and gasket replacement, pawl-bar and drive inspection, element and contactor checks, drain flushing, and a written final-rinse reading each visit. Districts and hospital systems typically run semi-annual plus a shutdown overhaul.
Will you leave documentation my health inspector will accept?
Every ticket carries the calibrated final-rinse manifold reading, the time it was taken, the machine identifier, and the corrective work performed. That is the record Minnesota Department of Health and municipal inspectors ask to see.
How fast can you get to a downed dish line?
Institutional and commercial accounts get front-of-line dispatch — same-day windows on most calls placed before 2pm, with after-hours and weekend emergency dispatch available across the Twin Cities. Call (651) 364-7466.
Do you carry Certificates of Insurance for property managers, hotels, and hospitals?
Yes. We issue COIs naming your property manager, hospitality group, hospital facilities office, or municipal account as additional-insured at no charge — typically the same business day. General liability and workers' comp are in force year-round; we can raise limits per contract on request.
What payment terms do you offer commercial accounts?
First visit is card-on-file or COD. Once an account is established, we invoice Net-15 or Net-30 with itemized statements aligned to your accounting cycle. We accept POs from restaurant groups, hotel brands, property management firms, school districts, and city and county accounts. ACH and card payments both fine.
Do you offer preventive maintenance contracts?
Yes — quarterly, semi-annual, and annual PM plans tiered by equipment count and equipment class. Every visit includes condenser cleaning, drain flushing, gasket and hinge inspection, electrical-tightness verification, controller and setpoint check, and a written report you can hand to insurers, health inspectors, or franchisors.
What refrigerants and fuel systems are your techs certified on?
Every technician holds EPA Section 608 Universal certification covering R-404A, R-448A / R-449A (Solstice N40, Opteon XP40), R-290 hydrocarbon systems where code permits, and legacy R-22. Cooking-equipment techs are gas-certified for natural gas and LP on ranges, fryers, ovens, and combi-ovens.
Do you handle downtown high-rise, hotel, hospital, and event-venue access?
Yes. We coordinate dock and freight-elevator windows in advance, badge in through hotel or hospital engineering, and work around banquet, service-window, and clinical-department timing. Overnight and pre-open service is available when a daytime window won't work.
Are weekend, holiday, and after-hours calls available?
Yes — after-hours, weekend, and holiday emergency dispatch is available for refrigeration, ice, and warewashing failures across the Twin Cities metro. A published after-hours premium applies and is confirmed in writing before the tech leaves the shop.
What warranty comes on commercial repairs?
A 1-year written parts-and-labor warranty on every commercial repair — the same failure mode, on the same unit, within 12 months is covered at no additional charge. Some sealed-system components carry an extended manufacturer warranty on top; those terms are itemized on the invoice.
Do you work on food trucks, ghost kitchens, and mobile catering rigs?
Yes. Truck-mounted reach-ins, undercounter units, generator-fed ice machines, and mobile prep tables are all serviceable — we typically shop-visit at your commissary or overnight parking rather than roadside so the unit can stabilize before diagnosis.
Can you provide written estimates and health-inspector documentation?
Yes. Written estimates are issued before any sealed-system, compressor, or major-component work. On request we provide inspector-ready documentation: repair scope, part numbers, refrigerant type and charge, and the date service restored the unit to spec.
Which Twin Cities cities and ZIP codes do you cover for commercial service?
Full Twin Cities metro — Minneapolis (55401–55488), Saint Paul (55101–55155), Bloomington, Edina, Eden Prairie, Maple Grove, Woodbury, Eagan, Plymouth, Minnetonka, Roseville, Burnsville, and the surrounding suburbs — plus Hudson, WI 54016 and Western Wisconsin. Commercial dispatch runs a daily route across the metro.
