My Solana TX hot tub won't operate. With power to the unit

Customer Question

My Solana TX hot tub won't operate. With power to the unit the LED screen shows the temperature set point with 3 dots across the bottom then after a minute the screen goes black except for the 3 blinking dots at the bottom.
when I push the button to operate the jets I can hear the relay make its clicking noise but the jets won't operate, or will the heater. The heater electrical connections on the heater look clean and I've already replaced the pressure sensor. What next?????

this sounds like a watchdog error.

At any time does the circulator pump run?...not the jets but the circ pump

Customer: replied 1 year ago.
No it does not run at all
Expert:  Billy replied 1 year ago.

ok this is the issue....we need too see if the pump is gettting power and not running (bad motor) or if the pump is NOT getting power (bad board)

Customer: replied 1 year ago.
Ok I'll check for power at the pump motor terminals. The hot tub is at my vacation home... I'll check that out next time I'm there

make sure to measure wire to wire and not wire to ground.

if any questions let me know

Wire to wire. Hopefully this weekend I can get down there.

Ok, I got down to the coast last weekend to check thing out. Found that no power is getting to the motor. I have power to the unit, checked at the heater terminals, the fuse, ok. Power to the hot tub light and the LED screen. if the board is bad do I need to replace the entire control Box?

If you have no power to the pump when you press for the pump to come on then the relay is most likely bad on the circuit board and you would need a new board, but if power to the pump and no operation it is the pump, check all fuses as some control boxes have fuses for the pumps. Replace all fuses if in doubt. Three dots usually indicate that the thermostat and or the high limit are not calibrated and need replacing but this can also mean no water flow so yes if all else is good the board must be replaced.
