FL error on hot tub

Hot tub displaying FL error sporadically. When error code displaying, hot tub stops circulating and heat drops. Have 2 sets of filters, and filters were last cleaned 2 weeks ago. Aqua-tech looked at hot tub fall 2017 for same issue and couldn’t find problem.

    Hi Graham. If you are working with new or very very clean filters, your water level is good and you have good flow through your circulation jet at the bottom footwell of the spa you could have an intermittent psi switch. If all else fails contact our Service Support Desk to book a diagnostic and repair of your Sundance Spa.
