It seems you have a bad pump 1. I would claim warranty on it where you purchased. This does happen. A local motor repair shop should be able to check it for you to see if it is bad. If it is you can get something in writing and usually you can just send the label on the pump back and save the shipping costs of returning.

If the pump is determined good then you have incorrect voltage pump (220volt vs 110Volt), it is too large in amperage (you have to go by amperage on pumps not the horse power as there is a large probem with ratings in our industry) or it is wired to the plug wrong. The electrical motor shop should be able to tell you that as well.

If you purchased the pump from Dynasty, get the hot tub serial number and have them match up what pump you need. If you purchased online, you need to get the original pump and look at the amps to see what you need.

I hope that helps and Happy Soaking.
