Howdy!
The main problem is that the agitator/spin motor doesn't run (front loader, AEG/Electrolux). The water pump, and all other electronics seem to work, and it goes through the error diagnosis on the control panel.
I checked the motor values, and it seems to be OK.
I looked over the MB, and I didn't like how the MB looked at the attachment points of the motor to the wiring harness, so I cleaned them up.
As I looked around more, I noticed on one soldered lead of a cap had a brown coating around it. (No, not glue). I took a picture AFTER I had cleaned it up a bit, you can still see some of the coating. I took measurements of that cap printed values are ELNA, 220 uF, 35V. The meter said 228 uF, Vloss = 2.1%, ESR=0.69.
OK, I thought, it looks like maybe it leaked, but the values look OK. It's about impossible to see the cap side of the board, the cap doesn't have enough clearance to see underneath it.
Since there's only 4 electrolytic caps on the board, I thought I'd check the others out, too.
Next two caps with the same printed value as above (ELNA, 220 uF, 35V) read:
445 uF, Vloss = 12%, ESR = .66
447 uF, Vloss= 12%, ESR = .69
Now for the last cap, printed value of LETON, 10uF, 400V, the meter reads:
DIODE Uf = 699mV, C= 10.2 uF!!
BTW, according the map of the circuit board, all the caps are in the power supply section, not in anything controlling the motor.
So, I'm confused as to why the motor is the problem, but the caps in the power supply seem to be the troublemakers.....
Thanks!
