The ground fault circuit interrupter or GFCI is a safety device that protects you from being electrocuted while enjoying your spa or hot tub. If a current of electricity were to run through the spa water, the GFCI would interrupt the circuit and shut all power off to the spa. A GFCI is mandatory for spa equipment to be up to code.
Sometimes, power surges or outages in the area can cause the GFCI to trip which will cut the power off from the spa unnecessarily. Simply push the reset button on the GFCI and see if the spa starts working again. If it trips automatically after resetting, you need a repair. Most often the GFCI will trip on a portable spa if the heater is going bad, because the protective coating on the heating element wears away and allows electricity to enter the water.
If you don’t have a GFCI on your spa, call to have one installed now to keep you and your loved ones safe! Below are examples of GFCIs that might be installed in the equipment area or at the breaker for your spa.
