Very simple...
Pr is only a brief "timeout" upon powering up the hot tub control system. Pr means - "Priming" Mode. That's it!
it will be in this mode for about 6 minutes.
Then system will revert to normal operation mode.
Good luck.
Follow this steps and fix it. God bless you
If the unit won't start, make sure power is on at the electrical outletor the electrical panel Then test the pump and the motor. Check for and repair broken wires or loose or corroded terminals. If necessary, have the pump switch control tested and serviced professionally.
If the jets do not work, clear a blocked water intake of hair and other particles (see below) or replace a broken jet (see below).
If the water in your spa or hot tub is too hot or too cold, check to see if the high-limit reset switch has been tripped and, if needed, reset it. Adjust the thermostat setting and have the thermostat serviced if the problem persists. If necessary, test and replace a faulty heating elements

That's too bad that your hot tub won't come on and you're getting a PR code. My own tub is acting rather strangely. It'll turn on, but it makes a lot of noise and distressed-looking bubbles. We should probably both find some hot tub repair to fix our problems.http://www.kaupaswater.com/maintenance.h...
