Commercial dishwasher repair is a narrower field than home appliance repair, and not every company that fixes a kitchen dishwasher takes on restaurant equipment. The Grafton list below starts with companies that mention commercial, restaurant or food service work within a longer drive, followed by the nearest appliance repair companies.

When to Call About a Commercial Dishwasher
- Leaks under the machine or from the doors
- Machine trips the breaker or will not power on
- Chemical pumps not priming or dispensing
- Dishes coming out with film or spots
Commercial dish machines come from specialist manufacturers, so ask whether the company works on your brand and can get parts for it.
Leaks and Safe Shutoff
Shut off the dishwasher's water supply during repairs or whenever it is leaking; the valve is usually under the kitchen sink on the branch line that runs to the dishwasher, and it closes by turning clockwise. Source: GE Appliances - Dishwasher Water Shut-Off Location
Built-in dishwashers are typically specified for their own properly grounded 120-volt branch circuit protected by a 15- or 20-amp breaker or time-delay fuse, with no extension cords or adapter plugs. Source: GE Appliances - Built-In Dishwasher Installation Instructions

Local Notes for Grafton
Most dishwasher calls in Grafton come down to the same handful of parts: the filter and drain path, the drain pump, the inlet valve, the door latch and the heating parts.
Wisconsin has no separate appliance repair license; plumbing licensing covers appliances connected to water supply systems, including water heaters, but exempts minor repairs to appliances and repair or replacement of gas or electrical control valves and devices.

In Wisconsin, you can check a license with the Wisconsin DSPS LicensE credential lookup or report a problem to the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), Bureau of Consumer Protection.
