Loud Noise from Maytag JetClean Dishwasher

Question

Hello,

The past 2 times I have tried to turn on my Maytag JetClean dishwasher within a matter of minutes I get a very loud noise.

I have checked inside and see nothing banging around or loose.

I have immediately shut it off when I hear this.

Also, right before this, I had been having problems with getting the top rack clean.

Thank you so much :)
Michelle
