My working hot tub suddenly stopped yesterday.
Control board has 240v power and topside panel has light and power.
There is a FLO error on the topside panel.
When i push jet 1, 2, 3, and light, the indication shows up but nothing really works.
The temperature was 95, so i don't think it is over heat safety sutt off.
My main pump does not have Mmmm sound at all.
I check the power to the pump motor (it is 240v 2 speed motor with four wires; photo attached).
only black wire has 110V, red wired has 0.
The pump is 8 years old and yesterday the weather was freezing.
Do i need to replace the pump or motor?
