I purchased a new Jacuzzi J375 and have been having "pump" issues since new (the tub is 5-weeks old). Some days they work...other days they do not (it is almost as if they trip out...I had an electrician review the wiring - no issue)...has anyone had a similar problem or issue? The "Jacuzzi" service tech indicated that they would replace both pumps as he did not exactly know what the problem was. I am wondering if it is the "board" and not the pumps.
