I had the same problem with my dishwasher. After hearing that the motherboard was the problem I decided to take a closer look. There were two capacitors (1000 microfarads, 6.3 volts) that looked a little suspect. The tops of capacitors should be flat...these looked like soda cans that had been left in the freezer. Got on eBay, located the capacitors for roughly $3 and $4 shipping, for approx total of $10. Soldered the two new capacitors into the motherboard and put it back together. As soon as I closed the door, the dishwasher started draining the water. When I ran a Normal cycle it completed successfully. Saved myself over $120!
it has few functions , so break them down to this.
does water flow in correctly . hot an cold
does the pump re-cycle water well inside . reflow lots of spray.
then does it pump out correctly an flow easily into garbage disposal , check the back flow valve for stoppage if it has one {its in the large plastic pipe right before the disposal.lets water flow but compactor garbage is blocked, it sticks a lot closed }
and is the door latch secure test it by opening suddenly is all you can do.
you might have to open the door quickly to check these items like spray or pumping.
TRY A RESET CODE
Press the "Sani Rinse," "Heated Dry," "Sani Rinse" and "Heated Dry" buttons on the dishwasher's electronic control panel in quick succession to put the appliance in diagnostic mode.
Close the dishwasher door and engage the door latch.
Wait 10 seconds before pressing the "Cancel" button to reset the dishwasher.

My plan was to see if I could find you a service manual, but strangely, the only reference to that model number is your post here! My guess is the D6 is 'D for Dishwasher' and 'Series 6' or 6 models in that current series.
If the machine has been laid up or little used, check all the connection on the control board. Clean pins and plugs with electrical switch cleaner

Please refer to youtube " Whirlpool Dishwasher Repair - How to Replace the Pump (Whirlpool # W11032770) "
The loud popping noise that you're hearing when you open and shut the door of your Whirlpool dishwasher (model # WDT780SAEM1) is most likely caused by the door gasket. The door gasket is the rubber seal that runs around the door, creating a tight seal when the door is closed.
Here are a few things you can try to fix the issue:
Check the gasket for damage: Inspect the door gasket for any tears, cracks, or other damage. If you find any damage, you will need to replace the gasket.
Clean the gasket: Over time, debris and food particles can accumulate on the gasket, causing it to become stiff and not seal properly. Clean the gasket with a mild detergent and warm water, and then dry it thoroughly.
Check the door alignment: Make sure that the door is properly aligned and not hitting the gasket when you open and shut it. If the door is not aligned properly, you will need to adjust it.
Lubricate the hinge: If the door gasket is in good condition and properly aligned, the problem may be with the hinge. Try lubricating the hinge with a silicone-based lubricant, as this can help to reduce friction and noise.
Contact Whirlpool: If you have tried all of the above steps and are still unable to fix the issue, contact Whirlpool customer service for further assistance. They will be able to provide you with additional troubleshooting steps or advice, or they may need to send a technician to repair or replace the dishwasher.
It's important to note that if the popping noise you're hearing is accompanied by other symptoms, such as leaks, then it may be related to a different problem, and you should contact Whirlpool customer service or a professional service technician for further diagnosis and repair.
