KitchenAid turns off 10 min into cycle
« on: July 17, 2016, 05:11:09 PM »
Model Number:  KUDS 30 IXBL1
Brand:  KitchenAid
Age:  1-5 years

 10 minutes into any cycle it turns off, no lights on, soap door has opened, water has been pumped out.
 Ran diagnostic: press any of 3 buttons in sequence, then repeat 2x: after beep saw "clean" light flash 6x, 4x.
 I see two pcb's: one in the touch panel, the other mounted to ss door. May I assume p/n WPW10500172, includes both?
 This unit has acted funny for some time: locking up and requiring disconnect/reconnect power to reset and run again; Sani-rinse light barely visible; a voice telling me I've won the lottery....

 I see there was a serv.bulletin: W10398386 - Control was revised due to a cycle stopping issue (serial numbers F032 to F105),
 Testing has determined that cycle stopping may result from a software error that can cause a false error code that
 cancels the cycle. Techs will see a 6-1 error code recorded in service diagnostics.

 Anyone know where I can get a "tech sheet"?

dab,

Thanks so much for the tech sheet and 6-1 error info.

My update: 
Following tech sheet for 6-4:
Float moves freely, when up, switch loses continuity (it opens).
I assume F9 is good since pump empties the water during diag test.
When drain hose is disconnected from sink drain and filled with water, water does not drain back into dishwasher.
I doubt there is any debris clogging the emulsifier, as I rinse dishes thoroughly before loading.
No problem with suds.
Not sure how to test fill valve function. I should run diagnostic program and open door after soap door opens?

Resistance across fill valve is 1072 ohms.
Maybe the pcb control board is bad?

Re-ran diagnostic program after cleaning connector contacts, etc.
Error codes 6-1, 6-2, and 2-1 were in memory.  The 6-4 error was not shown
until the end of the diagnostic program, which ended after 13 min.

I sure hate to buy a new dishwasher  :tickedoff:
Anyone have any ideas?
