I can’t seem to figure out why the light is blinking on my right portafilter.
My machine was on for 2 hours before I tired to make a shot! Once I did I realized the light was blinking & the coffee shot came out very slowly.
Any ideas why it would do this? It worked perfectly yesterday!

Any help is super appreciated!
Do you have an espresso machine technician you could call to troubleshoot? If not maybe cross post to r/espresso?
Call your local technician.
If you don’t have one, check out Service Layer Cooperative (servicelayer dot com) they may have a independent tech that is close by or can help you answer the question.
Or… call simonelli. Someone from they’re tech department might be able to explain what’s going on.
I can’t find a manual for your exact machine online but in the past a blinking start/stop button on older Simonelli machines indicated a steam boiler fill error. The user-servicable things to do in this instance is to make sure the water is on and flowing and that your water filter is up to date
