My dishwasher won’t respond to the keys pad,when press START to start the machine.
On the keys pad menu "Extra clean sensor selection" it has 6 item to choose: 1-Rinse only 2-China Crystal 3-Speed cycle 4-Normal cycle 5-Pot Pan 6-Anti bacteria. I can select #1 or #2 or #3, it doesn’t let me select #4 or #5 or #6.
I checked power supply, door switches, solenoid, wiring connection are good.
I don’t know, the KEYS PAD or THERMISTOR SENSOR or something else.
I did changed new control module assy 2 times, still does the same as the old module. Need help thank you very much.

Since you have replaced the control board I would say the keypad (Item 901 in Section 1) is bad.
Most keypads use a common line for a number of keys that is why 4,5 and 6 are not working while other keys are OK. The common has a problem.
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
If it is the type with a connector use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Reconnect everything and give it a try.
If this does nothing I would replace the keypad assembly.
