After a big thunderstorm where we had a power outage, the Soak/Scour light on our Whirlpool DU1055XTVB3 front panel started blinking. Tried the following:
1. Reset the dishwasher from the control panel (Press Normal-Heated Dry sequence several times) - all lights lit up, and it went through a test cycle and ended with all lights off. I thought I was done, and it ran a wash cycle successfully after that.
2. Then after a few days, the Soak/Scour light started blinking again. This time, I was not able to start the diagnostic cycle using "Normal-Heated Dry" sequence. Pressing any key results in that light blinking and no action.
3. Pressing Cancel/Drain button results in temporarily turning off the Soak/Scour light but it returns to blinking again and the Cancel button light also starts blinking
4. Turning off the circuit breaker and back on results in all previously blinking lights turning off, but the Soak/Scour light starts blinking again

The odd thing is that the Soak/Scour light was blinking in Step 1 and I was able to press the "Normal-Heated Dry" sequence to get all lights to light up and enter the diagnostic cycle.
Now the Soak/Scour light is blinking but I am not able to repeat Step 1 at all.

In between Step 1 and Step 2, we had another thunderstorm and another short power outage for a few seconds.

The dishwasher is about 9 years old and is used about twice a week. Is the front panel keypad going south with < 1000 uses? Most of the keys don't even get pressed, other than Normal and Sani-Rinse.
Did the power outage/surge cause the control board to act up and lock up with some error state?

Any advice on how to reset the control board or the front panel or how to tell what's the problem here greatly appreciated!

The front panel cost seems to be about $230 at Appliance Pros - does that sound right? Is that inclusive of the control board or is that just the keypad?

Thanks.

Hi, usually that indicates a short in the control panel touchpad assembly.

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 or the keypad. To determine if the control or keypad is faulty, do the following test:
Unplug dishwasher or disconnect power Open the dishwasher door. Open console and disconnect the keypad ribbon connection from the control (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 keypad unplugged), it will respond by turning on the drain motor for 2 minutes. Replace the keypad(control panel touchpad assembly) if the control board responds OK.

➔If the control bout is not OK (still sees shorts with the 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 you can order:

You see here how the control panel touchpad assembly fixed his:
