Yes,I know about the changes for 220 connections, and they were performed as per the panel on the control board panel I will try to take and post photos. Will the spa work any differently on 220 other than the heater shutting down during operation?

I have just purchased a used Catalina spa. The spa works fine on 110, but I have 220 hook up I would like to use, but when 220 is installed to the spa the black hot and white neutral have continuity, and of coarse trips the breaker. The line checks out when not attached to the spa. This doesn't make sense even an electrician looked at it and can't make sense of it. Other than the heater shutting off when the spa is operating, does the spa operate any differently on 220? And it doesn't seem to have a lot of pressure from the jets compared to my last spa (different brand) but would it being ran on 110 make a difference ?
