My hot tub continues to overheat. I keep getting the OH code. It run fine when the heater or jets are running. But as soon as the set temp is reached therefore the heater turns off and the jets are off. It flashes OH and will no longer turn back on. Any advice?

From my limited knowledge of tubs, this sounds like it could be related to the flow switch/sensor.

Q. Why does the control panel display "OH"?
Overheat protection may occur if the pump is set to operate for extended periods.
In extremely hot weather, check for proper cabinet ventilation.
When the hot tub is in a filter cycle, make sure P1 low-speed is on.
Check slice valves. Make sure that they are open.
Check for blockage in the filter cartridge, skimmer basket and pump intake fittings.
Check the alignment of the heater element in the heater housing to make sure it is straight and not contacting the sides.
Make sure the temperature sensor is installed properly.

Start by checking the filter. Remove it and try running it.
