Mamaroo clicking sound

Elephant in the hospital
Anyone have a mamaroo making a clicking sound? If so what was it and how did you fix it? I got a mamaroo (think 2014 or 2015 model) I made sure it worked and it's day tell my son got here. We just started using today work 2 hrs worked fine started it up again later on in the day now it has a clicking sound even with my baby in it
