please help! leisure bay hot tub

[nlv81]

Hopefully someone can help me diagnose the problem. I have a Leisure Bay hot tub & has been working great until recently. It'll start up for a few seconds but as soon as the jets kicks on, the fuse blows out. I replaced the fuse & the same thing occurred. What could be the problem? I hope its a easy & inexpensive fix. Thank you in advance. I can't wait to have my hot tub back

If it is the 20 or 30 amp fuse on the circuit board it is probably jet pump motor causing the problem.
