We have had our Barista Express for about a year now. Recently when using the double shot basket, the pressure only goes up to 8:00-9:00 on the dial. This morning my wife tried the single shot basket and it was at full pressure of about 10:00-11:00. She tried another and the results repeated. I then switched to the double shot basket. Same beans, same grind and it was back to 8:00-9:00.
