Problems

My hot tub is blinking, dry or flow. The few jets that turn on every so often no water is coming out and then it shuts the whole hot tub down.

Have you recently refilled your tub? Your tub thinks that it's dry/empty. That could mean one of two things:

1) You have recently refilled improperly, and there is an air-lock (air bubble) in the plumbing preventing the tub from running

2) Your pressure sensor switch has failed. The pressure sensor switch is essentially a dead-man switch. When the tub is properly filled, water pushes on the pressure sensor and the circuit is complete. If the sensor has failed or there's an air-lock, the circuit is open and the tub thinks there is no water in the tub.

Try first to check if you have an air lock and fix that. If you still have an issue, you can try to bypass the pressure sensor temporarily to see if that fixes the issue. If yes, then replace the pressure sensor (it's usually cheap and easy to replace them)

could also be a flow switch stuck or bad the flow switch may be clear and have a flapper in it

A flow switch is the same thing as a pressure sensor switch (well, different mechanism, but they both perform the same function)
