Own a Macap M7D. Usually performs significantly less like it has been possessed by a demon than it did this morning.
Over the past week, I have not needed to adjust the time that it grinds for (3.5 seconds), which has left the grind weight constant (around 18 grams), and have not adjusted the coarseness/fineness.
Every day INCLUDING THIS MORNING, I have been able to simply hit the button to dispense the grinds, receive my 18g approx into my basket, and brew a delicious shot of around 27g liquid in around 28 seconds.
As I said, this mornings 1st shot went great as usual. Then when I went to make my 2nd shot without changing anything on the grinder, I noticed 3 unusual symptoms:
1. Instead of the clump-free powder that usually comes out, it came out literally like a pile of small rocks.
2. Instead of my standard 18g output, I received around 10g. I tried this on subsequent attempts and continued to receive around half of the expected ground coffee.
3. As a 1st troubleshooting experiment I weighed enough of the output to get my standard 18g dose, and found that it completely blocked the espresso machine, ie it was much much finer than the grounds that I had used earlier today.
4. As a 2nd troubleshooting experiment, I adjusted the grind to make it much much coarser so that my 3.5 seconds grind actually delivered an 18g dose. This still blocked the espresso machine.
WTF is going on?
