We just refilled our jacuzzi hot tub.
The temperature is flashing as well as "FLO"
Then, after pressing the select button, the "CIRC" flashes as well!

Meanwhile, we refilled it last night, and the temp is still 87 degrees, as when we filled it....(We are in AZ)

Do I need to call a service technician?....I mean we just refilled it!

Help please

sounds like an airlock in circ pump system - force water down the filter with a hose or remove the tubing connecting to the circ pump to release trapped air
