Does the dishwasher need gfci?

You Might Be Surprised to Learn that Your Dishwasher Needs GFCI Protection. Most people don’t think about their dishwasher very often, except to load it and run it when dirty dishes pile up. But did you know that your dishwasher could pose a serious electrical hazard if it’s not properly protected? It’s true! In this blog post, we’ll discuss why your dishwasher needs GFCI protection and how you can make sure that yours is properly protected.

Why Dishwashers Need GFCI Protection

Dishwashers are one of the most common kitchen appliances, but they can also be one of the most dangerous if they’re not adequately protected. That’s because dishwashers use a lot of water, so they’re constantly exposed to moisture. And when water and electricity mix, it can be a recipe for disaster.

That’s why all dishwashers must be connected to GFCI (ground fault circuit interrupter).

Another revision to GFCI protection in the 2020 NEC is to section 422.5(A) dealing with appliances that require GFCI protection. This section was revised to include dishwashers. Yes, dishwashers! It’s hard to believe that an appliance that works so closely with electricity and water has not required GFCI protection prior, but the good news is, now it does.

GFCI receptacles have been around for about 40 years and are proven to significantly reduce the number of electrocutions. Without GFCI protection, an electrical shock from your dishwasher could be fatal.

  • After ovens, dishwashers are the second most common source of kitchen fires caused by non-cooking appliances. Dishwashers usually have a mix of electronics and heating elements, which can easily lead to an electric fire if something goes wrong. Remember to have it connected to a GFCI receptacle to avoid any risk of fire or shock.

How to Test Your Dishwasher’s GFCI outlet

How to Test your GFCI Outlet

  1. Plug a lamp into the GFCI outlet.
  2. Please turn on the lamp.
  3. To test the GFCI, push the TEST button. The correct result is that the electricity flow will stop to the lamp, and you’ll see the RESET button pop out.

If the lamp is still on, your GFCI outlet is not properly protecting your dishwasher. You should contact a qualified electrician to inspect and replace the outlet, if necessary.


Having a working GFCI outlet is essential for the safety of your home and family when using a dishwasher. If you’re unsure whether or not yours is working correctly, contact a qualified electrician to inspect and replace the outlet, if necessary. Doing so can save you from potential electrical shocks or worse. Taking these precautions will ensure that your dishwasher is protected against electrical hazards and keep you and your family safe.
