I just bought a used Morgan St. Thomas spa. When I hooked it up everything worked , but pump motor was getting loud. I replaced the main motor, wet end, and heater. When I hooked power to it, the control panel gave me a count down from 5 seconds to 0, then showed 1LOC. I've tried the LOCK-UNLOCK procedure in the manual, but nothing happens. Is there a factory lock out code I need? Any help would be appreciated. Thanks.
