Under what condition does a dishwasher not require GFCI protection?

The requirement for GFCI (Ground Fault Circuit Interrupter) protection typically applies to appliances that may be exposed to moisture, which could pose a shock hazard. However, under certain conditions, a dishwasher may not need GFCI protection.

The correct context is when a dishwasher is hardwired directly to the electrical system rather than being plugged into an electric outlet. A hardwired dishwasher, installed in accordance with the National Electrical Code (NEC) and local codes, is generally not required to have GFCI protection. This is because hardwired appliances are considered to have reduced risk compared to those that are plugged into outlets where water exposure is a concern, such as those in garages or areas prone to splashes.

Moreover, portable dishwashers and those installed in locations like garages usually require GFCI protection due to the increased risk of contact with water. Therefore, the distinction of being hardwired provides a specific condition where GFCI protection is unnecessary, making this an important consideration in electrical installations to ensure safety while also adhering to code requirements.
