Reparatieverslag - Saeco-HD8752 Coffee machine (English)

Finding the problem

The grindermodule is not working (common problem) for this specific machine. First I traced back the complete circuit for this grindermodule on the main PCB.

The problem I found is that resistor "R13" is defect and that optocoupler "ISO2" needs to be replaced.

The repair

I changed out the defective parts for new ones. Value "R13" = 330 ohm SMD type: 1206


On the left the old defective resistor, on the right the new replaced resistor.

The coffee machine has been put back together and is working properly again.
