Hello!
I have just collected a Magimix M100 Auto Coffee machine from someone on Freecycle, reported a "not working" turns out one of the thermal fuses strapped to the heater had gone (there are two, one on Live, one on Neutral, the Neutral had gone) I have replaced this, and it is now sort of working, where it was totally dead before.
It is controlled by a PIC 16f688, but the voltage on the vcc and Vdd pins is flapping all over the place, max I can see is about 2.5v
I did get it to dispence some hot water, while it was doign this, the light on the button was flashing, which was causing the light on another button to dim significantly on each flash.
So I assume the PSU is faulty, only, I am not really sure what makes up the PSU, as there is just one PCB, pictures are here
The heat-sinked IC at the top is a triac for the heater The small triac on the back, on the right is for the pump
I was expecting to see a 5v voltage regulator somewhere, but there isn't one - any ideas as to what might have gone south here?
The mains cables are, from the top - Live in Neutral In Pump Heater
I have a digital meter!
Thanks for any pointers!
