Smeg EGF03: the EGF03 pressure gauge is an extraction indicator; grind, dose and filter choice should be adjusted in small controlled steps rather than by opening the machine. Use the exact model and light or message pattern before changing a setting. The checks stay within removable brewing, milk, water and drip-tray items described by the manufacturer. What this exact symptom means: the EGF03 pressure gauge is an extraction indicator; grind, dose and filter choice should be adjusted in small controlled steps rather than by opening the machine. What to distinguish first: Confirm that the displayed or observed condition exactly matches “use pressure gauge to check espresso extraction” before changing anything. 1. Confirm the model and signal — Confirm that the displayed or observed condition exactly matches “use pressure gauge to check espresso extraction” before changing anything. 2. Prepare the appliance safely — Complete the normal shutdown, unplug the machine, let hot parts cool and empty the drip tray before removing user-accessible parts. 3. Carry out the official user check — Select the documented dispensing filter, dose and tamp evenly, brew one shot and note the gauge; change only one grind or dose variable before the next test. 4. Interpret one controlled retest — Reassemble every part in its documented position and run one short rinse or one beverage. A repeated signal after the stated check requires service rather than repeated resets. The official Smeg page documents this model-family symptom and the user-level procedure above. Keep water out of the bean hopper, grinder and electrical openings. Never force a brew unit, valve, grinder control or hot steam part. Stop and contact the manufacturer if the same signal returns after one correct cycle, a grinder contains a foreign object, a hot-water leak appears or the machine trips power.

Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
