HAs anyone seen this on a hot tub spa?

Question

I have a 2005 Dynasty Spa. I recently moved it and wired it up today. After filling, it worked fine but blew a lot of dirt out of the lines. I emptied it and when I filled it back it and turned the power back on, the pump #2 is just turning on and off and can not get it to stay off. Pump #1 seems to work fine. Has anyone seen this behavior. This happens before priming.

Answer 1

Yes I ran into this for the first time last week.  !st cause (most likely) the 220v pump is somehow wired for 120v.  When it was moved or wired after moving perhaps someone moved one of the wires?  If that is not the case then it is the circuit board's relay is failing.  Hopefully for you it is the wire.

Answer 2

might be air trapped in line?

Answer 3

It might be a bad top side control. Try disconnecting the top side control from the main control unit.
