Hot tub error codes help diagnose issues with a spa's heating, water flow, and electrical systems.
These codes vary by manufacturer but typically indicate problems related to sensors, pumps, or power supply. Below is a general guide to common hot tub error codes and their meanings by popular manufacturers.
| Error Code | Meaning |
|---|
| pd | Power supply on battery backup |
| OH | Sensors reading 112-118° F |
| OHH | Overheat. One sensor has detected 118º F. Spa has shut down. |
| OHS | Overheat. One sensor has detected 110º F. Spa has shut down. |
| Flo | Improper flow/pressure switch error |
| Cool | Water temp 20° F below set point |

| HFL | Substantial difference between temp sensors detected. Could indicate a flow problem |
| LF | Persistent low flow problems. (Displays on the 5th occurrence of "HFL" message with 24 hours). Heater is shut down, but other spa functions run normally. |
