2. Kinks in any tubes can cause flow problems in the machine which could cause unusually
high flowrates.
3. Incorrectly calibrated.
Action required:
1. Check the valve and remove and reseat it if necessary.
2. Check for kinks in all hoses.
3. Recalibrate the water dispense. If a dry basket is used during calibration then some water
may be retained in the basket giving a lower estimate. If hot water is left to stand then some
may evaporate giving a lower weight when weighed, so the machine will dispense too much
as it thinks it has a lower flowrate than it actually has.
GRINDER OUTPUT
The grinder works on a timed basis, estimating how many grams are dispensed per second. During
calibration if the grinder is empty and clean then grinds will cling to the grinder components and the
10 second calibration grind will dispense a lower weight than if the machine was in normal
operation running for 10 seconds. So before calibrating a small amount of beans should be passed
through the grinder.
Adjusting bean type, roast, humidity, grinder settings etc. can also result in higher/lower weights
than expected.
