Dear Saeco forum specialists; i have a little problem with my machine. The door switch caused a short cirquit on my powerpoard (SAECO IG 1.9.30.231.00_v00) and blown the fuse (F2) and a ( i assume) resistor closeby, near the 8-legged switching chip (Q0265R). Does someone have a value of this resistor ( called C78) or does anybody have the electrical drawing somewhere available? Sorry for non german post, am not a native german speaker. Vielen dank!
just something new (as some of you probably noticed) that i assued C78 to be a resistor but it is more likely to be a ceramic capacitor. My apologies!
The short has damaged the switching power supply. Normally it creates regulated 8 VDC and 24 VDC. The 8-pin DIL-chip Q0265R is a Fairchild switching regulator. All capacitors are marked with a C and a number on the board. Since ceramic SMD capacitors are not labeled by the manufacturer and Saeco does not publish schematics, nobody can tell you the correct value of capacitance. Try a 100 nF substitute and see what happens. regards Harry
