SnA & SnB Spa is shut down. The sensor that is plugged into the Sensor “A” jack is not working. The sensor is not reading properly. Unplug sensor and switch sensors around. If the problem switches to SnB, then you have a bad sensor. If the problem stays SnA, then you have a bad PC board. Same with the error SnB.
SnS Sensors are out of balance. If this alternating with the temp, it may just be a temporary condition. If the display shows only this message(blinking), the spa is shut down. Shut the spa off for 20 min to reset the power. If the problem comes back, try and unplug the sensors and switch where they are plugged in. If you still have a problemyou either have bad sensor or PC board.
