Hello, this unit died about 1 month after the warranty expired.  I have replaced the Noise Filter & the Main Control Board.  It will still not turn on when pressing the power.  The red light comes on on the Control Board when I turn on the breaker, but nothing happens when I try to push the power button.  I have tried the "reset" function, and nothing happens.  What else could it be?

    I am trying to avoid paying the service fees on a 1 year + 1.5 month old dishwasher that has already had a catastrophic failure that was covered under the warranty. This is the 2nd Major Failure since i've owned it. My old junky one lasted 19 years, and I had hoped this LG one that matches all  my other LG appliances would have lasted longer.

    The troubleshooting for no power would be the same.

    I have the same issue. After a cycle, the diswasher doesn’t power on. The dishwasher in on a single circuit. I tried to close the breaker and lite on several times, the red light under the dishwasher turned on but not the power, neither anything on the control panel. The only way i found to repower the dishwasher is by separate the black wirings (connection between the power line and the dishwasher wire under it) than with power still in the main circuit, reconnect it to the dishwasher wire. It will cause a spark that seems to wake everything up.... Weird but it worked for me. That’s the third time in less than 2 years that this problem is happening...

    Just had the same thing happen with my dishwasher.   14 months after purchase date.   Didn't think I needed to buy extended warranty's with LG products due how long my previous appliances have lasted.   1 service visit for $89 and then $$$ on control board and still not working.    Piece of junk.   Posting my review on Best Buy.

    It seems that I may have bought the wrong brand dishwasher.  It seems several people are having the same problem I am having.  My LG LDP6797st is experiencing no power to the control panel.  I’ve had the dishwasher for 13+ months.  It seems to be the same for several people on here.  I’m very disappointed in this product.  And I refuse to pay to have someone come out to fix this problem that is certainly “NOT” isolated to me.  I purchased this item from Lowe’s, and wish I hadn’t.  LG wants me to pay a repair technician to come out and evaluate it and resolve the problem.  Hey LG, a lot of people are having the same exact problem in the same amount of months since purchase.  Most likely not a coincidence.

    I purchased my Dishwasher exactly a year and 1 month ago and I am having the same issue. Maybe it is a warranty issue.
