Hi all,
I have a Kenmore Ultraclean dishwasher model 665.15777990 that I've managed to fix. However it's stuck in some odd diagnostics / debug mode where choosing a cycle results in most of the LEDs lighting up, I think telling me what individual stages will be run.
Any idea how to exit this mode? Actual front panel below.
To verify my repairs, I put it into the diagnostics mode outlined in the technican's manual under the kickplate, which is a 1-2,1-2 sequence for this model Water-Heat,No-Heat-Dry , Water-Heat,No-Heat-Dry ; 2 seconds later it kicks off a full cycle, much time later the diagnostics complete, green light comes on the at the end, so good news is it's working again.
However, when I try to use it normally (i.e. "Normal Wash") way more than the 'Normal Wash' LED turns on, and when I hit start, it runs the selected cycle to completion. Trying other modes, many different LEDs light up, leading me to think the dishwasher is displaying what steps it will run for a given mode (i.e. Quick washer has fewer stages than Normal Wash).
No matter what I've tried (holding down canel, start, cancel+start, 1-2-3 key sequences, turning power off for 24 hrs, even pulling the main PCB and discharging the four capacitors) it still ends up in the "extended" display mode. Re-trying the 1,2 , 1,2 sequence just lights up ALL LEDs and restarts the extended diagnostics mode.
Any suggestions here?
I can take a picture of the front panel LED state for a given mode if that's helpful as well.
