Welcome to our forum.
There is no way for me to set the pump to low speed. I only have the option on the topside panel to switch it between high and off. The manual for the hot tub says it should cycle between low, high, and off. I've read that there could possibly be a switch on the back of the pump that is stuck on high speed, but I couldn't find anything like this. Not sure what to do now.
I just switched the high and low speed wires coming from the pump on the board itself and now the hot tub cycles between off and low speed when I hit the jets button.
