Error Code
4HR error code — Gecko spa
Always cut power at the breaker before opening the spa pack or touching wiring. Spa equipment runs at 120/240V and can be lethal. If you are unsure, hire a licensed spa technician.
4HR is Gecko noticing a filtration cycle that never ended. It's programming more often than parts — but a pressure switch that can't confirm flow will also keep a cycle running.
What 4HR means
Filter cycle exceeded 4 hours of high-speed pump run.
Diagnose in order
- Review filter-cycle programming — a mis-set schedule is the usual cause
- Test the pressure switch; a flaky switch can keep a cycle from completing
- Check pump behavior at high speed
