hey, i cam across this in midst of my curiosity of how my laundry machine works. im just going to say this outright, i'm just curious about electronics and the principles in which they work, so i'm not trying to steal, i like to know how everything works, from my car to fermenting my own brew.. now that ive said that, i think a few of you guys were on the right track, maybe this will help us all out, i have the wiring diagram, pictures of the guts and what ive done so far to make it function without the card reader. i'm not into any crazy reverse engineering projects, i honestly just do stuff that seems to make sense and see where it goes. this is probably the closest learning project ive come to actually completing without giving up, so what im saying is i'm not too technical, so if i need to explain myself further please let me know. from what ive gathered it would be a better idea to bypass the card reader from even working, you know just run "diagnostics"
ive noticed there are two modes you can access when you put in the single white jumper(#14) "Fd mode" which i have no freakin clue what it does, other than the fact that it allows me to do what appears as some diagnostics
and factory mode, which will be discussed later. that shit is confusing too.
by default, the washer is on jumper #09
Fd mode can be accessed by removing the power to the washer, placing #14 onto the selector harness. you press the "whites" and start button for 3 seconds
while writing this i just noticed something in the schematic they forgot to take out of the machine,
the other selector plug harnesses are decoded
the number is indicated on the plastic plug on each set of wires, the last two numbers
#09-short wash cycle
01- long wash cycle
02- short wash cycle with extra rinse
14- service mode
ive been running it in service mode, and im able to fill it up with water, drain the machine and thats about it. if you tinker with the buttons different functions happen, in my next post, ill clearly label all the functions, and scan in a copy of the schematics/wiring diagram(pub number 31-16508)
ok heres some pictures to let you know whats going on visually (dont have a scanner anymore sorry i took pics of the diagram)
first, heres a diagram for all you guys who know how to read these. i bet this will help a little
heres the decoder for the wire coloring
heres the actual board, everything should be in view that you need to see, if not tell me what you need
the jumpers and harness for card reader
interesting thing i found inside the card reader - regular pc jumpers? i wonder what the heck they do? i cant seem to find any info on this unit, and i dont have any extra jumpers laying around...but i will have some soon because i found this
factory mode
first off i have no clue how i got here, let me try to explain.
i unplugged the washer, plugged in jumper number 14 and flipped the switch by the selector harness from "flash" to "normal" and plugged it back in
this mode operated completely different, it allowed me to run one cycle then i couldnt get it to come back to factory mode, and now i get this everytime i unplug or plug the machine in
no load enable!!!!!!! what?
no clue, at this point i'm lost, and just gathering some ideas. i just wanted to make sure i shared this with you guys, because there is alot of good advice on this site that ive used. basicaly my goal is to just bypass the card reader, which i dont think it would be that hard to do. im going to do some more experiments, and then come back and post some more. hope this helps
