So I'm new to this hot tub thing. I just got a new filter, but the hot tub keeps flashing "----" on the read out screen. It's an older model, so I need some help please. It an 8 person tub, that about all I know. If I turn of the breaker, and then turn it back on, it resets sometimes. When I get it to reset, it may run for a day, or just 3 mins.
Signed. HELP!
