Kenmore dishwasher 665.12773K310 diag code not listed

[BoredAgent]

Hi.  I've put my dishwasher into diagnostic mode and it reports a code 3-4.  I checked the technician paperwork taped inside the toe panel and there is no code 3-4.  I see that generally, code 3-x relate to the thermistor/owi.  Any thoughts on what a 3-4 code means?

I'm also getting a 6-6 code for inlet water too cold.  I don't believe that is accurate as I make sure the water is good and hot at the sink before starting the cycle.

Thanks for any assistance.
