Dishwasher is 7 yrs old. I operate dishwasher in NORMAL wash mode with Heated dry turned off. Starts to wash normally and will then stop (time varies). Keypad lights will turn off and turn back on with same NORMAL wash mode light illuminated but now the Heated Dry light will also be illuminated. I'll then turn the Heated Dry option off, push the START button and the dishwasher may run normally or run and stop again like before. Sometimes it may take up to 2-4 tries of restarting the unit for the it to run normally.

Have turned breaker to dishwasher off to reset it multiple times without any change in problem.

My initial thought was control module was bad.
Did perform the Service Mode tests and unit does what it's suppose to per Service mode results. Have also visually looked at control module and it looks brand new. Key pad ribbion cable is not damaged. Also verified that there is no corrosion on connections to control module and that all of them are tight.

Any suggestions as to the control problem.
Thanks for your help!
