Hi, I went to the beach for a quick getaway, left the pump on parents were home thought all would be ok. Dad called said pump/motor wasn't working, and I dont think he knew for how long. When I got back the flex pipe from the pump to the filter had blew off causing the motor to be dry. I reinstalled pipe and turned back on the pump/motor seems to work but the longer its on it gets real real loud. Is this the bearings, please tell me I dont have to replace the motor I did so last year. Any and all questions and advice are welcomed.
