Most common repairs needed to fix a LG dishwasher
PCB Replacement
A dishwasher that won't power on could have a defective printed circuit board (PCB). The PCB, also called an electronic control board, will freeze up and fail to power up the control panel when its internal memory and logic is corrupted. A failed internal electronic relay or bad electronic part on the circuit board could be causing the control board to fail. Determining whether a control board is defective is difficult. Schedule service with a Sears Home Services technician to diagnose and repair your dishwasher if it won't power on.
User Interface Control Replacement
When the dishwasher won't power up, a damaged user interface control could be causing the problem. The user interface control connects to the electronic control board through a wire harness and sends signals to the control board to help manage the dishwashing cycle. A stuck key on the user interface control can cause the electronic control board to stop the cycle and the dishwasher won't work until the damaged user interface control is fixed. Have a Sears Home Services repair expert visit your home and replace the user interface control if it's damaged.
Wire Connector Replacement
If your dishwasher won't power on, a stripped wire connector could be causing the problem. Several different wire connectors inside the dishwasher can keep the dishwasher from working if wires get disconnected. The wires inside the junction box must stay connected for the dishwasher to get power from the power cord. The wire harnesses on the electronic control board and user interface control must also stay connected to keep the dishwasher working. When your dishwasher isn't working, have a Sears Home Services Repair Expert visit your home and fix the problem.

Sears Home Services recommendations for a dishwasher won't power on problem
When a dishwasher won't power on, it can be for many reasons. To avoid replacing unneeded parts, we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.
What to look out for with a dishwasher won't power on diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

Thorough
James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
