Philips EP5360/10 - Coffee Lack & Grinder Block Detection; Coffee Cycle Overview

PHI 5000 03 OPERATING LOGIC
3/8
When the coee grinder is working, the soware monitors the current consumption. If the current value is
very low, the machine concludes that coee is missing; if the current value is very high, the machine concludes
that the coee grinder is blocked; instead, if the current value is in the middle, the machine concludes that all
is ok and it goes on to do the product.
Because the current consumption of grinder changes depending on the situations (motor new or old, cold or
hot, coee blends, etc.), these current targets are not static, but dynamic.
