It beeps when it's done.
It beeps when you press the button.
It beeps when you place it on the base.
But today, it beeps no more.
I classify this as a repair.
I did the same thing to my refrigerator. The lights flash and it beeps in a piercing tone when you leave the doors open too long. The flashing lights is enough, I took apart the door and found the controller board and just popped the speaker off. Unbothered.
