Since the last serious health problem of Incanto, a lot has happened. I don’t want to go into details about them (ya’ll know, the virus and stuff) but want to mention that after Incanto’s last surgery five and a half years ago, Incanto worked flawlessly. But recently out of a sudden, it had hick-ups when booting in the morning. It took a few rounds of reboots to actually start. One could see Selftest in the display, the motor of the coffee press started to spun for a few milliseconds, and then the display was dead. This process repeated with increasing motor runtimes until the motor selftest was finally done and things worked normally.
One workaround I found out was to send Incanto into sleep mode before powering it off and keeping it in sleep mode for a few minutes after power on in the morning. This let the Selftest perform without motor activity and once waking up from sleep mode everything worked normally. At that point, I had the suspicion that a capacitor is not working properly anymore but I did not do anything (yet). This worked for a few weeks but then things became worse: the machine did not start anymore at all. All one could see was Selftest in the display for a few milliseconds and then reboot without any motor activity.
Checking the schematics of similar machines on a web forum, I found out, that it was a simple 230V/9V transformer, a bridge rectifier and a 5V linear voltage regulator. A classic setup, which also comprises of a 470µF capacitor on the 9V side of the regulator (which I expected to be the culprit) and another one with 22µF on the 5V side.
So I simply replaced the 470µF capacitor and now Incanto is back in business, grinding and brewing fresh coffee for more years to come.
