The FIL message indicates that the Filtration system has been activated.

A green indicator light will turn on and no action is required.

NOTE: The Filtration system cannot be activated at the same time as the Bubble/Jet Massage function.

Pressing the Heat Button activates the Heating and Filtration systems at the same time as the water needs to circulate to heat. In this case the green indicator light and red indicator light will be activated at the same time.

If you see "FIL" interchanging with "CHG", this indicates "Change Filter". Please see our solution V1 PCU Display Messages - "CH6 FIL/CHG FIL" for more information.

If you require any further assistance, please contact Customer Service.
