My LG dishwasher stops running 5 mins in

fault with the programe as it has stoped in mid cycle

In new installations, this error can sometimes present because of a miscommunication between the control panel and the wash motor. In this instance, the washer simply needs to be reset.

Step 1: Unplug the washing machine.

Step 2: While the washer remains unplugged, press and hold the [Start/Pause] button on the front panel for 5 seconds.

Step 3: Plug the unit back in, and run a rinse and spin cycle to test if the LE code is cleared.

OVER SUDDSING

Hi,
Here is a tip that explains what the LE error code means.....

LG Washing Machine LE Error Code or Fault Code
heatman101

ie means water
le is pump bad

Motor is going out. Replace the sump assembly.

bad sensor replace main motor

The LE error code can mean that the impeller is damaged or there is some debris blocking the the sump area underneath the filter or the wash motor has failed. In that order.
Remove the spray arm and filter (9 phillips screws) - inspect impeller for damage, with flashlight, look everywhere for debris (watch out for broken glass!) Reassemble and test.
If problems continue, schedule as service call focused on the wash pump/motor.
Good Luck!

If you are still having problems with your LG dishwasher, turn off the hot water supply to the dishwasher and remove the hot water inlet pipe (remove the lower, front panel (toe kick plate) )
Check the screen/filter at the water inlet on the dishwasher.
Reconnect the pipe and turn the hot water supply back on.
Test out and enjoy!

Checking in to see if your resolved your problem already.
Having the wiring harness melt is, of course, serious and potentially dangerous. Recommend you contact LG service with the model & serial # and firmly but politely require action from their service department.
Good Luck!

L2 error code is the same as an LE error code.  You have a problem with the sump motor assembly and needs to be addressed by a qualified LG technician.
