Hi.
I have a hot tub with Balboa GS500Z and Wellis ACM0681 dual speed pump. When at high speed/jet it only runs for 2-3 minutes. (should run for 15 minutes) Anyone know what the problem could be?

Let’s see if @RDspaguy can give you an assist when he comes around.

Does it still show the jet indicator? Does it turn off or go back to low? Is it a new board or pump? Are there any errors on the display?
