What kind of buzzing? like the drying chcle ending alert or like electrical arcing? if the latter, dont use it until you have an electrical inspect.

Bravos is a marketing label, not a specific model. Model numbers are necessary to correctly identify an appliance for technical questions.

Noises are largly impossible to diagnose without hearing them. Does the machine have an end-of-cycle buzzer, is the buzzing the same as that sound? Is it a mechanical noise? Something metallic rattling or vibrating? Suggest you take a video of a minute length or more, place it on YouTube or other public sharing service and link it in a reply post.
