We have older beach comber tub that we shut down each winter. This spring when we filled it, the water curculates and heats as supposed to. When we use touch screen pad to turn jets on they don’t work. Pump sounds like it is trying to move into higher speed but as I said the jets don’t come on. I tried to attach a video but wasn’t successful. Anyone else had this issue? Any ideas on what could be wrong. 1 pump only.
