We cleaned the unit but dont know what else to do. It is located in a church kitchen and is piped directly into the plumbing. It was calibrated one year ago by Starbucks affiliate but now is brewing shots that are too large.
Hi Adjust the grinder towards fine ,to do that check the collar of the beans hopper you will find circular dots bigger and smaller ,hold with both hands and turn towards small dots do both sides.
secoundly you can open flap of hot water and steam ,press and hold program button and increase the amount of coffee on each drinks.
Aways use fresh beans,no more than 2hrs in machine.
That could either be an increase in water pressure or the shot timer needs to be reset to a lower value.
