This also happens to me occasionally. I think it's the temperature pressure. Machines are becoming more and more human, i.e. more sensitive(!) The coffee is just as good despite the low pressure.
With kind regards

As far as the Quick Mill Orion 3000 is concerned, my machine has a consumption of 1080 watts. That is around 1 KW per hour. If I never switched the machine off, it would have an annual consumption of 9,460.8 KW. The 287.4 would therefore be about 3.3% of the annual continuous consumption. This would correspond to a daily operating time of 47-48 minutes. HG
