Weak Espresso Flow and Grinder Trouble on Built-Ins

When shots that once poured steadily turn to a tired drip—or the grinder shrieks—the machine is telling you about beans, burrs, or water.

Adjust one variable at a time on Fisher & Paykel automatics so you know what helped.

Grind Size and Bean Condition

Too fine a grind plus oily dark beans can choke flow and load the grinder. Stale beans powder unpredictably. Move grind coarser slightly and test.

Weak Flow Water Side

Scale narrows tubes and valves. Incomplete descale leaves the same symptoms. Also confirm the water tank vent is not blocked.

• Clean the brew unit on the recommended cadence.
• Vacuum stray grounds from the grinder throat if the manual allows.
• Avoid flavored oily beans in automatic grinders.
• Run a cleaning tablet cycle when prompted.

Grinder Noises and Stalls

Foreign objects, pebble fragments, and worn burrs create harsh sounds. Power down before any inspection the manual permits.

Service-Level Repairs

Clogged brew valves, failing grind motors, and damaged burr sets are replacement jobs. Forcing the grinder risks burning the motor.

Safety note: Never insert knives into the grinder. Unplug before clearing accessible chutes.

Frequently Asked Questions

Why did flow worsen after darker beans?

Oils coat grinders and brew paths; switch beans and clean thoroughly.

Is watery coffee the same as weak flow?

Watery can mean under-extracted grind or dose issues; true weak flow is a volume/time problem.

If cleaning and grind tweaks fail, schedule coffee system service rather than repeatedly stalling the grinder.
