Troubleshooting-Gaggia-Platinum-Grinder-Cleaning

Do the cleaning and calibration instructions in this video:
After reassembling the machine according to these instructions do not add beans in. First make sure the grinder adjustment knob is set to the coarsest setting, which is the largest dot.
Add beans back into the machine. The beans must be dry, do not add oily beans back into the unit.
If this clears the alarm light and shots are pulling successfully on this grind setting then you can move the grind back to the original setting. Only move the knob one dot at a time, brewing a shot in between each adjustment.
