Quick answer
How often should a commercial dishwasher be serviced?
A commercial dishwasher needs daily cleaning by staff, weekly nozzle and arm cleaning, regular deliming, and a technician inspection of the pumps, seals, heaters and chemical dispenser on a schedule that fits your volume and water. Most kitchens with hard water should plan on a technician visit every 3 to 6 months. We service Hobart, Jackson, CMA, Champion, Insinger and Meiko machines.

What a dishwasher maintenance visit covers
Deliming
Scale on the tank, heater element and rinse system cuts water temperature and cleaning performance. We delime on the schedule your water calls for.
Temperature and gauge checks
Wash and final rinse temperatures verified against the data plate. If a machine can't reach temperature, the heater, booster or thermostat is next.
Chemical dispenser checks
Detergent, rinse aid and sanitizer feed lines and pumps checked for flow and leaks. Concentration settings are coordinated with your chemical supplier.
Door-type, conveyor and undercounter units
The service differs by machine, so the visit is built around what you run: door-type, conveyor, flight, undercounter or glasswasher.
Service record
A dated written record you can keep for inspections, franchisors or insurers.
Why it pays
Why dishwasher maintenance pays off
Clean dishes depend on temperature
A machine that doesn't reach its wash and final rinse temperatures leaves dishes that look clean but aren't sanitized. Catching a failing heater early is what maintenance is for.
Hard water is the quiet killer
Scale builds on heater elements and clogs spray nozzles, so machines run longer and use more energy before they fail. Twin Cities water makes deliming a regular job.
Fewer service-hour breakdowns
Most dish machine failures start as small things: a worn curtain, a leaking seal, a weak pump. Finding them on a schedule beats finding them mid-rush.
One vendor for the kitchen
The same team handles your dishwasher, ice machine, refrigeration and cooking equipment, so you manage one vendor and one record.
Repair or replace?
Should you repair or replace a commercial dishwasher?
| Situation | Our recommendation |
|---|---|
| Worn curtains, clogged nozzles, scale on the heater or a weak pump | Maintain or repair. These are the parts maintenance is designed to catch. |
| Machine won't reach final rinse temperature even after deliming | Heater element, booster or thermostat. We'll quote the repair. |
| Tank or frame corrosion, or repeated leaks at the welds | Usually replace. We'll tell you before you spend money. |

Your maintenance checklist
Commercial dishwasher maintenance checklist
1. Daily: close-out
Scrape plates before racking. At close, drain the tank, remove and clean scrap trays and strainers, wipe the interior, open the door and leave it ajar to dry. Check the detergent, rinse aid and sanitizer levels and confirm the wash and final rinse temperatures at the start of service.
2. Weekly: arms and nozzles
Remove the wash and rinse arms, clean out the nozzles and end caps, and check that all spray holes are open. Wipe door seals and curtains and look for cracks or tears.
3. Monthly: inspect
Check the curtains and door gaskets for wear, look at hoses and fittings for leaks, check the drain valve, and look at the heater element or tank for visible scale. Test the final rinse sanitizer with test strips.
4. Quarterly: technician service
Delime the tank and heater, inspect pumps, seals and thermostats, calibrate the chemical dispenser and verify temperatures against the data plate. Call (651) 364-7466 to schedule, seven days a week from 7am to 9pm.

FAQs
Dishwasher maintenance questions
How often should a commercial dishwasher be serviced?
Staff should clean it daily and weekly. A technician should inspect and delime it every 3 to 6 months, and more often if you run it all day or have hard water.
What should a commercial dishwasher maintenance checklist include?
Daily: drain, clean scrap trays and strainers, check chemicals and temperatures. Weekly: clean the arms and nozzles. Monthly: inspect curtains, gaskets and hoses. Quarterly: technician deliming and inspection.
How do I descale a commercial dishwasher?
Use a manufacturer-approved delimer in the tank and run it through a cleaning cycle, following the label. Scale on the heater element usually calls for a technician.
How long does a commercial dishwasher last?
With regular maintenance, many last 10 years or more. Hard water and skipped maintenance shorten that considerably.
How much does commercial dishwasher maintenance cost?
It depends on the machine type and how often you want service. Maintenance is quoted per visit, in writing, before we start.
Why are my dishes coming out dirty or cloudy?
Common causes are clogged spray nozzles, low wash temperature, a weak detergent feed or hard-water scale. A maintenance visit usually finds the cause quickly.
What temperature should a commercial dishwasher reach?
For a high-temperature machine, the FDA Food Code calls for a final rinse of at least 180°F at the manifold (165°F for a single-temperature stationary rack machine), and no higher than 194°F. Chemical-sanitizing machines work at lower temperatures, so follow the data plate and test the sanitizer concentration with test strips.
Do you service glasswashers and undercounter dishwashers?
Yes. We service door-type, conveyor, undercounter and glasswasher units. See our commercial glass washer repair page for bar and taproom machines.
Do you offer commercial dishwasher maintenance near me in Minneapolis and St. Paul?
Yes. We service Minneapolis, St. Paul and the surrounding metro, plus western Wisconsin. Call (651) 364-7466 to set up a visit.
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.
