Services covered

Industrial dishwashers we repair

Flight-type machines (Hobart, Stero, Meiko)

Conveyor drive motors and gearboxes, peg belts and flight bars, curtain sets, tank heaters, pre-wash and power-rinse pumps, blower dryers, and controls. Scheduled outside meal periods so the tray line stays fed.

Typical repair: $685–$1,950 parts and labor, plus the diagnostic

Rack conveyor machines (Hobart, Champion, Jackson AJ series)

Pawl bars, drive links and motors, wash and power-rinse pump motors, fill and rinse solenoids, curtains, and tunnel re-timing to your rated racks per hour.

Typical repair: $585–$1,650 parts and labor, plus the diagnostic

Pot, pan, tote, and utensil washers

Heavy-soil machines in commissaries and bakeries — wash-pump rebuilds, tank element and probe replacement, door and hood gaskets, scrap-trough seals, and drain-line service.

Typical repair: $485–$1,250 parts and labor, plus the diagnostic

Booster heaters and peak-load rinse recovery

Hatco, Hobart, and Jackson boosters — elements, contactors, high-limits, transformers, and full deliming. We test recovery at peak rack count, not at idle, so 180°F holds through the rush.

Typical repair: $485–$1,150 parts and labor, plus the diagnostic

Three-phase electrical, contactors, and controls

208/240V and 480V three-phase troubleshooting — element megging, contactor and overload replacement, phase and voltage verification under load, PLC and membrane-panel faults. Board work only after the load fault is identified.

Typical repair: $485–$1,250 parts and labor, plus the diagnostic

Deliming and sanitization verification

Tank, manifold, and booster deliming on hard water, curtain and gasket replacement, drive inspection, drain flush, and a written final-rinse reading per visit.

Typical repair: $385–$785 parts and labor, plus the diagnostic

Repair vs. replace

Why repair an industrial dishwasher instead of replacing it?

Scheduled around meal periods, not around us

Hospital tray lines, school lunch waves, and banquet nights get early-morning or between-service windows, 7am–9pm every day. We confirm the window before the truck rolls so your dish room is not down at peak.

Repair versus replacing the line

A flight-type or rack-conveyor line is a major capital replacement. Drive motors, pawl bars, curtains, elements, and boosters are wear items, and replacing them is usually far cheaper than replacing the machine.

Peak-load testing, not idle testing

A booster that holds 180°F at idle can fail at rack 40. We test recovery under real throughput and size the fix to your peak, which is why these calls don't come back two weeks later.

Written sanitization readings for inspectors

Every visit ends with a calibrated manifold temperature reading, time-stamped on the ticket — the documentation Minnesota Department of Health and municipal inspectors ask for.

Written quotes for institutional accounts

School districts, hospital systems, universities, and food-service contractors get a written quote before work begins and a 1-year parts-and-labor warranty on repairs. The commercial diagnostic is $175–$299 and is not credited to the repair.

Summer and shutdown overhauls

Campus and district kitchens can get a written quote for shutdown periods — curtains, gaskets, pawl bars, elements, and deliming completed before the first service day.

If your equipment is down right now

If your industrial dish line is down mid-service

  1. 1. Switch to manual warewashing and document it

    Set up 3-compartment wash / rinse / sanitize at correct temperature and chemical concentration per your HACCP plan, and log the time you switched. Inspectors ask for that log.

  2. 2. Verify power, water, and drain at the machine

    Check the three-phase disconnect, confirm the hot-water supply valve is fully open and delivering 140°F or better, and make sure the trough and floor drains aren't standing.

  3. 3. Clear the tunnel and inspect curtains

    Pull racks, clear the scrap trough and screens, and look for shredded or missing curtains. Missing curtains alone will drop tank temperature and drag racks.

  4. 4. Write down the fault code and where the cycle fails

    Note whether the machine fills, heats, conveys, then fails at rinse — and any PLC or membrane-panel code. That detail routinely saves a return visit.

  5. 5. Call a commercial warewashing technician

    Booster, three-phase, drive, and control work needs a commercial technician. Call (651) 364-7466 early and say your dish line is down so we can look for a same-day window.

Symptom answers

Industrial dishwasher symptoms — cause, fix, and what it costs

High-volume warewashing fails differently than a door-type machine. Below is what we actually find on flight-type and rack-conveyor lines, what we do about it, and the parts-and-labor range, plus the diagnostic. Smaller door-type, undercounter, and glasswasher units are covered on our commercial dishwasher repair page.

Flight machine racks stall or dishes pile at the tunnel exit

Usually drive-motor or gearbox wear, a stretched drive chain, a worn pawl bar, or shredded curtains dragging the racks.

We amp-test the drive motor and gearbox, replace worn pawl bars, drive links, and peg belts, fit a full curtain set, then re-time the conveyor to your rack-per-hour rating and log the throughput before we leave.

Typical repair: $585–$1,650

Why does the final rinse drop below 180°F at peak service?

Usually a failed booster element or contactor, a scaled booster tank, booster recovery too small for the peak rack count, or incoming hot water below 140°F.

Booster recovery — not the machine — fails first on institutional lines. We test element resistance and amp draw leg to leg, replace pitted contactors and drifted high-limits, delime the booster tank, and verify incoming supply at 140°F+ so the booster isn't doing the building's job.

Typical repair: $485–$1,150

Why does my conveyor's tank temperature drop between racks?

Usually a failed tank heating element, a fouled level probe, a weak contactor, or low fill from a failing fill solenoid.

Tank heaters and level probes get fouled by starch and protein soil. We meg the tank elements, clean or replace the level probes, verify the contactor and thermostat, and re-check fill volume so the wash tank recovers between racks.

Typical repair: $485–$985

Machine trips the 3-phase breaker or drops a leg

Usually a shorted element, a pitted contactor, a failed overload, or a loose lug or phase imbalance in the disconnect.

We meg each element leg to ground, check contactor and overload condition, verify phase balance and voltage under load, and replace only the failed load — a control board goes in after the fault is found, never before.

Typical repair: $485–$1,250

Why is my blower dryer leaving ware wet?

Usually a failed blower motor or element, a plugged intake filter, a blocked air knife, or a rinse-aid injector that lost its prime.

Blower-dryer motors, heating elements, and air knives are tested under load, filters cleared, and rinse-aid delivery coordinated with your chemical vendor so ware air-dries in the rack rather than getting hand-toweled.

Typical repair: $485–$1,150

Pot and pan or flight machine leaking under the tunnel

Usually a weeping wash-pump seal, a failed tank or hood gasket, a cracked vacuum breaker, or a split manifold union.

We rebuild pump seals, replace tank and door gaskets, re-seat the scrap-trough gasket, and pressure-check the fill and rinse manifold so water stops running onto the dish-room floor and into your slip-hazard log.

Typical repair: $385–$885

What happens when the inspector flags low sanitization?

Usually a scaled rinse manifold, a booster that can't keep up, blocked rinse jets, or chemical dosing out of spec.

We verify manifold temperature with a calibrated thermometer at peak load, correct the failure that caused it, and leave a written reading on the ticket that documents the corrected value with time and date.

Typical repair: $285–$685

Cycle times stretched and production dropped after a few months

Hard-water scale on the manifolds, elements and jets is the usual cause.

Hard water scales tanks and manifolds over time. We delime the tanks, rinse manifold, and booster in a single visit, then re-verify temperatures and rack throughput so the line is back at its rated capacity.

Typical repair: $385–$785

Facilities we serve

Where industrial warewashing lines run in the Twin Cities

Hospitals and senior-living kitchens

Tray-line flight machines and rack conveyors that cannot go down between meal periods. Early-morning and between-meal scheduling, and written sanitization readings for your facilities file.

School and university dining

Rack conveyors and pot-and-pan machines under district and campus contracts. We schedule around lunch waves and can quote summer-shutdown overhauls in writing before August.

Stadiums, casinos, and event venues

Peak-load warewashing that runs hard for a few hours and sits idle the rest of the week. Booster recovery and conveyor timing are common failure points in these rooms.

Food production and central commissaries

Pan washers, tote and crate washers, and utensil lines running on 208/240V and 480V three-phase. Sealed-component and control work is quoted in writing before we start.

Hotel banquet and conference kitchens

Flight machines that carry a 400-cover banquet, then sit. Deliming, curtain sets, and drive maintenance keep them from failing on the first big night after a slow month.

Corporate cafeterias and corrections food service

Contract-fed dining rooms with fixed service windows. We confirm the visit window and give a written quote before work starts.

FAQs

Industrial dishwasher repair questions

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?

Tank heater, level probe, and solenoid work lands $485–$985 in parts and labor, plus the diagnostic. Conveyor drive, pawl-bar, and curtain work runs $585–$1,650. Booster and blower-dryer repairs run $485–$1,150. Sealed or major control work is always quoted in writing before we start.

Can you work between meal periods?

Yes. We work 7am–9pm every day, so hospital tray lines, school kitchens, and banquet dish rooms can be scheduled early in the morning, between meals, or during shutdown periods. We do not dispatch overnight. We confirm the window before dispatch.

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. Hard water 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.

Can you repair 480V three-phase dishwashers?

Yes. Our technicians troubleshoot 208/240V and 480V three-phase warewashing machines — testing elements, verifying phase balance under load, and replacing contactors and overloads. Building wiring beyond the machine disconnect goes to a licensed electrician.

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?

Same-day appointments are available from 7am to 9pm every day, including weekends. Call early at (651) 364-7466 and tell us the dish line is down so we can fit you in.

How much is a commercial appliance diagnostic?

Commercial diagnostic is $175–$299 depending on the equipment; it's billed separately from the repair, and you get a written quote before any repair work.

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. We accept ACH and card payments.

Are weekend calls available?

Yes — we work 7am to 9pm every day, including weekends, with no weekend surcharge. Same-day appointments are available for equipment failures across the Twin Cities metro; call early. We do not offer overnight or holiday dispatch.

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.

Can you provide written estimates and health-inspector documentation?

Yes. Written estimates are issued before any major-component work. On request we provide inspector-ready documentation: repair scope, part numbers, 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.
