Whirlpool dishwasher GU2455XTSQO KEEPS RUNNING TIMER DOES NOT ADVANCE, I have replaced the thermostat, checked the element for continuity(good), and have now replaced the control computer board, after installing the new board I also ran the diagnostic program to calibrate sensors. I then started dishwasher in normal cycle and it ran for about 10 min with no time display, then it displayed 99 min ran for 2 more min then stuck on 97 min for over 15 min, which at that time I shut it off. Any suggestion what I may try from here 
, How much further should someone go on a item of this nature:cool: Also where and what is the Thermistor, could this be the problem ? Water temp is 120-F TO 125-F I am told by local appliance repair shop that the unit is not heating up to wash temp of 140-F and it just keeps running until that happens ? Any help or thoughts will be appreciated. (kknursey@yahoo.com)
