I have a Jacuzzi J-355 model hot tub. It's about 5 years old. I've been getting a Flow 2 error code - I replaced the filters and adjusted jets once to fix it. Its back on again... I adjusted the jets again to try and augment the flow but it didn't work. I bought a new switch to replace the old on but I can't find it on the hot tub. The flow switch from the circuit board seems to go directly into a metal casing behind the control box that I assume is the heater. Do I need to take this apart?
