My machine is a DeLonghi Magnifica ESAM3500 , though this may apply to other models as well. It all started after I ran a descaling cycle on an otherwise faultless machine.
- Coffee would drip during the pre-infusion phase of brewing, then stop and continue brewing,
- Too much coffee is brewed to the point of overflowing your cups
- Rinsing cycle at power on/off takes too long and too much water is poured.
Needless to say the coffee tastes like crap.
