Product review (5 stars): May Need to Also Replace the Control Panel...
Replaced original with this circuit board because all of the lights on the control panel took turns blinking but only the "Drain" button responded to being pressed.

After replacing the circuit board with this new one, only the "Normal" button and one other button blinked.

Read online that if after replacing the circuit board, the dishwasher still does not work then the control panel&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Whirlpool-Part-Number-3385734-PANEL-CNTL/dp/B002ZHXS32/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Whirlpool Part Number 3385734: PANEL-CNTL</a>&nbsp;(sold separately) should be replaced as well.

Once I replaced the circuit board AND the control panel, our Whirlpool Quiet Partner II now works "like new" and my wife and I no longer need to see a marriage counselor;-].
