I have a 5 year old Whirlpool dishwasher Model # SUD600HQ1 under the
Kirkland Quiet Max logo from Costco. It has touch pad buttons.
Suddenly, some keys, including the one for "Normal" and "Pots & Pans"
have stopped responding. I can still run a complete wash cycle on the
"Low Energy" or "China" program.

I opened up the door panel and pressed in all the connectors firmly but
no luck.

How can I isolate if the problem lies with the Control Board or with
the keypad?


Is the keypad replaceable? Where can I buy one? Is there anything on
the control board that I can check with a multimeter?

Any pointers are most welcome as I feel I am on a short lease until the
remaining keys also stop working.
Thanks.
