    We experienced a 7 second power outage, and now my hot tub won't filter. The heat, and bubbles work, but when I push the filter button, it gives me an e90 message, and when I push the reset button, it pops back out. What can I do?

    Possibly an air lock. Try This

    Press the button to turn off the unit. Release trapped air by
    unscrewing the drain valve cap on the control base side with a coin.
    Air has been release once a steady stream of water is flowing out from
    the drain valve. Wait for 15 seconds and screw the drain valve cap
    back. Press the button to activate the control panel buttons, and
    then run the filter function by pressing the button to push out any
    remaining air in the system.


    If you have the manual look under Troubleshooting.


    Go to the intex support site - https://www.intexcorp.com/support/ and in drop down list select "Spa" in next drop down list select Your Model then select "Submit" then select the Spa you have then the Manual.
