Hey everyone,  This dishwasher has me completely stumped.  It is Model No: 665.13929K010 and Serial No: F03401896.  I'm getting a 6-4, 9-1, 6-3 & 8-1 fault codes.  The customer says it will not run thru the complete cycle, but they don't know when it stops because they always start it at night and go to bed.  The dishes are not clean in the morning.  This model has a diverter valve on it that turns all the time in the wash cycle.  Is it supposed to or should it stop at times?  What does the diverter do?  I never seen one before.  This dishwasher is all electronic and boy do I miss the good old days with timers and switches.  Everything is so complicated now a days.  I cleared out the fault codes and told them to try it again.  I sure could use a service manual on this model to learn how this thing works.  Please help me out if you can.  Thank You, Tom

The last one I saw with those codes was over-sudsing from the wrong detergent.  I don't believe it had the 9-1 diverter code so you may have a bad diverter. I have attached the tech sheet.

The diverter is a motor that drives a disk with a hole in it. The purpose is to allow water from the pump to flow to either the bottom washarm or the upper rack wash arm. It should pause, not run continuously. The diverter motor has a momentary contact position switch that tells the control board when the motor has reached the next position. The problem could be wire connections to diverter, a bad diverter or possibly a bad control.

Thanks for all your help.  This sure seems confusing but I'll take the service manual with me and check it out.  I'll let you all know how I make out.  Thanks Again, Tom

There are 2 red wires that come off the switch (part of the diverter motor assembly).  I hooked up a ohm meter to the 2 red wires at the control board and ran the dishwasher.  The diverter motor would not shut off and I never seen any change of the meter as the switch should have opened & closed.  So today I replaced the diverter motor. I hope this works.  I'll let you know how I make out.  The next step would be to replace the control board.  Hope I don't have to.  Thanks!

Sorry I forgot to ask.  In the box with the diverter motor was a wire connector, wire harness and a fuse (I think).  There were no instructions with the motor so I do not know where the wire harness goes.  If you know, please tell me.  Thanks!
