Record a Restricted Espresso Flow for Model-Specific Troubleshooting
Restricted or absent espresso flow needs the troubleshooting procedure for the exact machine and basket. Record what happened and the preparation used before changing inputs. A small dose change cannot be promised to restore flow or produce a particular yield and taste.

Stop under the machine's instructions
If flow is abnormal, follow the maker's stopping and troubleshooting procedure. Do not unlock or handle a hot or pressurized portafilter based on a generic inspection suggestion. Establish the required safe state first.
Record the actual preparation
Keep the machine, basket, dose, grind reference and observed flow together. Use suitable measuring equipment where the maker supports it; a scale reading is an observation, not a diagnosis of the entire machine.
Use the basket's supported dose guidance
Consult the actual basket capacity and machine preparation directions. Do not apply generic basket ranges or automatic dark-roast reductions to every setup. Use a supplied dose tool only as directed.
Describe one adjustment without guaranteeing a result
Where the instructions support an adjustment, record what changed and what occurred in that preparation. Delete the earlier illustrative case's guaranteed dose-to-yield/time/taste outcome; it was not a verified result.
Keep distribution and tools equipment-appropriate
Use the maker-supported distribution and tamping method. Do not prescribe a needle tool as a universal remedy or claim that every stalled shot has one simple mechanical cause. If supported checks do not resolve the problem, use the maker's service route.
A little more
to know.
Can a screw imprint distinguish dose from grind as the cause?
Not reliably as a universal rule. Follow the machine's actual troubleshooting and safe-state procedure before any inspection.
Should I predict a fixed flow change as beans age?
No. Record the actual preparation and use supported adjustment guidance; bean age alone does not establish the cause or correction of restricted flow.
