Seeing a GCF error on your Lay-Z-Spa? This frustrating issue, known as a Ground Circuit Fault, often points to a fault within the main control circuit board—especially if you’ve already tried a different power outlet and confirmed your home’s grounding is in good condition.
Our Lay-Z-Spa circuit board replacement is the solution to fix GCF errors and restore proper heating to your hot tub.
What Causes GCF Errors?
A GCF error (Ground Circuit Fault) is a safety alert triggered when the spa detects a grounding issue. While this can occasionally relate to your household electrical setup, in many cases the fault lies within the spa’s main circuit board—particularly when:
-
You’ve tested multiple sockets
-
Your home’s electrical grounding is verified
-
The spa continues to display the GCF fault upon power-up
Replacing the main board resolves this issue in most cases.
