Light flashing over soap scour button, will not do anything. Worked fine and the next day the light was flashing. Tried to reset from control panel to no avail.

Hi,

Usually its a short in the control panel touchpad assembly that causes this problem.

Here's a test to determine which part is the problem:
A blinking LED over one of the keys of the keypad (or sometimes a “dead” keypad/console) indicates one or more key switch lines are stuck or shorted on the control board or the keypad. To determine if the control board OR control panel keypad is faulty, do the following test:
Unplug dishwasher or disconnect power, then Open the dishwasher door. Open console and disconnect the keypad ribbon connection from the control board (at P1). Make sure all other connections are made. Put console back together. Do not close the dishwasher door. Plug in dishwasher or reconnect power. Wait 5 seconds. Close dishwasher door. Monitor the control’s response.

➔If the control board is OK (no longer sees shorts with the control panel keypad unplugged), it will respond by turning on the drain motor for 2 minutes. Replace the control panel keypad if the drain motor turns on.

➔If the control board is not OK (still sees shorts with the control panel keypad unplugged), then the drain motor will NOT respond. If drain motor does not start within 10 seconds, repeat or verify that all steps were followed, and then replace the control board.

Here's the control panel touchpad assembly for your model:

Thank you Jake. It does allow me to run if I catch it when light is not flashing. Does that make a difference?

That still indicates the control panel touchpad assembly has a intermittent short in it, so the control panel touchpad assembly is culprit itself.
