Bought it 4 days ago. Used it twice for the frappe setting. Went to make some coffee this morning, turned it on, I put the coffee grounds in, the water, and hit hot brew and the hot brew button and the on/off button just keeps blinking fast. It won't brew.  Thought it was just the "hot" setting tried the others... The "over ice" didn't work and the "blender and pulse" didn't work.
