Troubleshooting-Gaggia-Unica-General-Error

These lights blinking simultaneously is a general error signal for the machine. This error signal is used as a catch-all for atypical machine errors. Do not confuse this with a similar machine signal, which is the middle row of lights blinking in rotation; this means the machine is rinsing.

1. The brew unit did not engage properly for some reason. If this signal appeared when you heard the brew unit moving, then it likely has something to do with the brew unit or brew unit motor.
   1. Restart the machine. Sometimes this error simply means the brew unit was blocked or did not engage properly and restarting the machine will resolve the behavior.
   2. If the error is still occurring refer to the section of this article that discusses brew unit cleaning and lubrication. Make sure the brew unit is cleaned and lubricated according to the instructions.
2. The grinder may be blocked. If you get this error when the grinder goes to activate in particular, then it likely indicates an issue with the grinder mechanism. This typically happens if beans are being used that are not compatible with the machine. This machine does not accept oily, caramelized, or flavored beans. Use of these beans can cause permanent damage to the machine that is not covered under warranty. These beans can be identified easily. They will be shiny and feel slippery or sticky. Dry beans that are appropriate for the machine will look dull and feel rough.

1. 1. Do the cleaning and calibration instructions in this video:
   2. 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.
   3. Add beans back into the machine. The beans must be dry, do not add oily beans back into the unit.
   4. 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.
2. If the signal still has not cleared then there is an internal issue with the machine which will require a repair.
