Hot tub temperature

Red light is on in hot tub. Fairly new filter. Tub recently drained and refilled. Tub not heating up to set temperature at all. Waterfall running. Jets seem to be working. Error message is FLO then the temperature flashing back and forth. Not sure what to do. Thanks.

  1. Hi Robert. The inner micro clean filter is the one that could cause the flashing FLO message. Make sure this one is clean. As a test you could remove both filters briefly ie 10min to see if the flashing FLO message goes away. It’s also common to experience and air lock after a fresh fill. The easiest way to aleviate an air lock is to loosen the suction union at the smaller circulation pump until the air is released.
