Turn off all power to the hot tub as soon as you realize it is overheating. The spa should have an automatic shut off when the water temperature reaches about 112 degrees fahrenheit. Call your hot tub dealer or manufacturer for service options. There are a variety of conditions that could lead to the overheating of your hot tub, but may differ in various hot tub models and brands. Check the water level of the hot tub. Low water levels could be the culprit for the over heating, so you may just need to add more water to the hot tub.
Check the shut-off valves in the hot tub. If they are closed while the hot tub heater is on, it could cause the water to reach unsafe temperatures.
Clean the hot tub filter. A dirty filter could be blocking the flow of water, causing the water to sit in the hot tub and overheat.
Turn the power back on after finding the problem and talking to the hot tub dealer. The hot tub will probably not start back up until the water reaches a safe temperature

The F5 error code indicates a water temperature problem. The control board circuit is not recognizing a resistance change in the water temperature sensor.
