Around Jefferson
Most dishwasher calls in Jefferson 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.
