How Commercial Dishwasher Repair Works
Here’s what happens from your first call until your dish machine is washing, rinsing and sanitizing again.
Call or Request Online
Call 508-419-9010 or request service online. Tell us the machine type, whether it’s high temp or low temp, and what’s happening: not heating, not draining, failing sanitizer strips or leaving film. A dish room that can’t sanitize is a line that can’t serve, so say so if you’re mid service.
Rapid Dispatch
We dispatch a technician who covers your town, prioritizing machines that have stopped sanitizing. Because Harris Warren also supplies warewashing chemicals, the technician can check the dispenser, the chemical lines and the machine itself on the same visit instead of sending you to another vendor.
Diagnose & Repair
The technician finds the cause, whether it’s a failed booster element, a worn dispenser pump tube, a stuck drain valve or clogged wash arms, and repairs it with parts from the van when they’re in stock. If a part has to be ordered, you’ll know what it is and when it’s expected.
Test, Document, & Follow Up
Before leaving, the technician runs a full cycle and verifies final rinse temperature or sanitizer concentration, so you have proof for your town’s board of health inspector. The work is documented and backed by Harris Warren’s 90 day parts and labor guarantee.
THE HARRIS-WARREN DIFFERENCE
Why Choose Harris Warren For Commercial Dishwashers?
A down dish machine stops a kitchen faster than almost any other failure, and a machine that runs but doesn’t sanitize puts your inspection at risk. Here’s why Cape Cod operators trust their dish rooms to Harris Warren.
Highly Skilled Technicians
Harris Warren technicians train through Tech24 University and understand both sides of warewashing: the mechanical and electrical systems in the machine and the chemistry that makes it clean and sanitize.
We Stock the Most Commonly Used Parts
Vans carry the dish machine parts that fail most: booster heater elements, thermostats, fill and drain solenoids, wash arm bearings, door gaskets, curtains and dispenser pump tubes, so more repairs are finished on the first visit.
90-Day Guarantee
Every repair is backed by Harris-Warren’s 90-day guarantee on parts and labor. If the same problem returns within 90 days, we come back and fix it at no charge.
Planned Maintenance Programs
Scheduled visits cover wash and rinse arms, booster heater calibration, dispenser and chemical line checks, gaskets and curtains, and delime or cleaning as needed. Seasonal kitchens can book a startup visit before opening and a check at the height of summer.
All Machine Types & Configurations
Undercounter, door type, conveyor and flight type machines, high temp and low temp, from compact bar glasswashers to banquet sized conveyors in resort kitchens.
Chemicals And Service From One Team
Harris Warren supplies warewashing chemicals and services the machines that use them. When spotting, film or a failed test strip shows up, there’s no finger pointing between a chemical company and a repair company; one team checks the dosing and the machine together.

FREQUENTLY ASKED QUESTIONS
Commercial Dishwasher Repair FAQ
Answers to the questions we hear most about commercial dishwasher and warewashing repair. Don’t see yours? Give us a call.
High temp machines sanitize with hot water; most must reach 180°F at the final rinse manifold, and single tank stationary rack machines 165°F. Low temp machines sanitize chemically, usually with chlorine, at the concentration on the machine’s data plate, commonly at least 50 ppm.
Massachusetts follows the FDA Food Code, and your town’s board of health checks these during inspections. Test sanitizer strips or temperature labels daily and keep a log. If readings come up short, switch to manual sanitizing and call for service.
Repair usually makes sense when the tank, frame and wash system are sound and the fault is a heater, valve, pump or motor. Consider replacing when the tank is cracked or corroded, parts are no longer available, or the machine keeps failing during peak season.
It’s also worth weighing high temp against low temp. High temp machines need a booster heater and more energy but use less chemical; low temp machines cost less to run on power but rely on sanitizer. Because Harris Warren sells new equipment and supplies chemicals, your technician can price both paths.
Much of Cape Cod’s water comes from its sole source aquifer and tends to be soft and slightly acidic. That means less scale than in hard water regions, but it also means detergent and rinse aid are easy to overdose, which causes film and foaming.
Water varies by town and between the Cape and Plymouth County, so dosing should be set for your actual supply rather than a generic setting. Your technician can check how your water is behaving in the machine and adjust the chemical settings to match.
Yes. Harris Warren provides commercial and restaurant dishwasher repair from its West Yarmouth office across all of Barnstable and Plymouth Counties. That covers Hyannis, Dennis, Falmouth, Mashpee, Sandwich and Harwich Port, and across the Cape Cod Canal to Wareham and Plymouth.
Technicians live in the communities they cover, and machines that have stopped sanitizing are prioritized, since a dish room that can’t sanitize can’t legally keep serving.
Yes. Harris Warren supplies warewashing chemicals and repairs the dish machines that use them. Having one team responsible for both means problems like spotting, film or failed sanitizer tests get diagnosed as a whole, not bounced between a chemical supplier and a repair company.
Chemical dosing that’s set for the wrong water, or a dispenser pump that’s worn, can look like a machine problem. When the same technician checks the chemistry and the machine, the real cause gets fixed on the first visit.
