I am losing my mind here. I really hope someone can help. My hot tub is a morgan oceanside. It has a gecko s class with a single pump. The pump is a flomaster xp2. The tub runs fine at high speed, then switches over to circulation mode with no problem.....while its heating. Thing is, once it reaches temp, if it's in circ mode, it'll shut off, which it's always done, but once the temp drops and it tries to turn circ mode back on it hums for a couple seconds then shuts down, throwing a 3 dot code on the panel. It did this a while back and the motor bearings were whining loud. So I changed the motor out and the problem went away......for about three weeks. When it throws the code I have to shut the breaker off.when I flip the breaker back on I have to run over and hit the pump button on the panel to get it running. othrwise it will hum for a couple secs and shut down with the error code. Help!!!!!!!
