Something to be mindful of---when servicing a recently installed LG dishwasher...
"I've just purchased this dishwasher. It throws an error of "nE" about 5 minutes into the cycle and refuses to run a complete cycle."
"I've contacted Customer Service because I could not find the definition for what the "nE" error was---and they too were unaware of what it means."
The customer had a plumber install the dishwasher for them---and most plumbers are not too savvy installing *tall tub* dishwashers as they are with pipes/drains:)
Especially if the kitchen has a "built-up" floor.
In this case---the plumber opted to use *solid* copper pipe rather than the flex/stainless water line.
During the installation---the plumber struggled to get the dishwasher under the counter.
Once that was accomplished---the plumber declared success and submitted a bill and left.
The problem was that during the forced/shoving of the dishwasher into the counter space---the copper water line had damaged the MICROSWITCH (3W40025C)---which "tells" the Main Board the position of the Vario/Stepping Motor.
This Motor & Switch---re-directs wash water from the lower wash arm---to the middle & upper wash arms and back---approximately every 90 seconds.
If the Main Board does not receive confirmation that the position of the Microswitch has changed---this will trigger an error of "nE" (which is not listed in the Owner Manual and most Service Manuals).
Installed new Micro Switch and Stainless Steel Flex Water Line.
