CHECKING KEYPAD OPERATION
A rapidly blinking LED over one of the keys of the keypad (or sometimes a "dead" keypad/console)
To determine if the control or keypad is faulty, do the following test:
1. Unplug dishwasher or disconnect power.
2. Open the dishwasher door.
3. Open console and disconnect the keypad ribbon connection from the control (at P1).
Make sure all other connections are made.
4. Put console back together. Do not close the dishwasher door.
5. Plug in dishwasher or reconnect power.
6. Wait 5 seconds.
7. Close dishwasher door.
8. Monitor the control's response:
If the control is OK (no longer sees shorts with the keypad unplugged),
it will respond by turning on a Drain Motor for 2 minutes.
Check and/or replace the keypad if the control responds OK.
If the control is not OK (still sees shorts with the keypad unplugged),
then the drain motor will NOT respond and will remain off.
If no response, replace the control.

I had this, there are two circuit boards, one on the front under the switches the second in the back near the compressor. which is really hard to reach, your guessed it, its the one near the compressor that needs replacing, its around 70 pounds stirling..

I think you still have warranty, it sounds you have faulty control panel, even if it's new does not mean it is good.

One of your bulbs is out. Turn your flashers on and walk around your vehicle to see witch one it is and replace it.

see this causes and fix it. God bless you
Thermal Fuse If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work.
Door Switch The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.

Main Control Board The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. YOU should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.
Touchpad and Control Panel If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced. On some models the touchpad and control panel are sold together and will need to be replaced at the same time.

Timer The timer allows power to flow to the proper parts at the proper times. If the dishwasher won't start, the timer might be defective. Keep in mind that timers are often misdiagnosed as the cause of a problem. Check other components first before replacing the timer.

Not sure, but I've heard a bad hazard switch can cause strange problems.
Also, if your truck has a body control module that controls interior and lights, that may be your problem, too. Good luck.

Push and hold power freeze and power cool simultaneously until display flashes. Release and leave alone. You just reset the brain on your display. In an hour or so, reset the desired freezer and refrigerator temps. My suggestion, -6 on freezer, 44 on refrigerator.

Sounds like a electronics problem would need to replace the board, LG parts are not normally expensive.

I have the same problem. I've tried everything;even took apart the control panel and checked for corosion. I ended up changing the control board-$130 down the drain- The only other thing I can figure is the button panel has some sort of short- also ~$130-. good luck. Now I use the sink (wife's not happy) Tech sheet is behind kick plate.
