The FIL message shown by itself indicates that the Filtration system has been activated. This message will appear when the unit switches back to filtering after the Jets have been deactivated.

The red Heat indicator light will be on and no action is required.

NOTE: The Filtration system cannot be activated at the same time as the Jets function.

Pressing the Heat button activates the Heating and Filtration systems at the same time since the water needs to circulate to heat.

If you see "FIL" interchanging with "CHG", this indicates "Change Filter". Please see our solution V2 PCU Display Messages - "CH6 FIL/CHG FIL" for more information.
