Did you look in the goop inside the door?
Notes from fearless leaders previous LG DW woes:
To disassemble the door start by removing screws behind the panel. All connections to control are color coded. Remove the latch and wires. Lift front panel off. Disconnect wires, remove exhaust fan assembly rotate cover ccw and yank out assembly. Remove the door by removing side plates to get door springs off.Pull down on springs and lift out clips remove ground wire and lift door off.Remove sprayer and plastic tube to top sprayer. Remove all screws on top of motor assembly get screen off keeping gasket in tact for reuse, next take the reverse thread screw off the impeller, get the nut grader out. Tip dishwasher on side and remove 2 base panel screws. Remove the retainer screw and retainers that hold the assembly to the bottom. Disconnect the motor assembly wires. Disconnect the hoses. Remove the ground wire nut (10 mm) Push in tabs where white clips were and lift out the motor assembly. Nothing to it.
all LG dishwashers (2004-2010) use the same SUMP ASSEMBLY.
Problem: What is the correct part number for the motor/sump assm. Ive seen updated and improved part numbers and I want to make sure I get the best one.
Solution: As of this posting---all LG dishwashers (2004-2010) use the same SUMP ASSEMBLY.
Note: The AJH31248604 Sump Assy replaces all
previous Sump Assemblies.
THESE WERE THE WASH MOTOR FAILURE SUMPS
THESE WERE UPDATED FOR ENERGY EFFICIENCY
AND/OR REDUCING MANF'G COSTS
The current replacement, Part # AJH31248604
Reply from consumer: Thanks! Before calling for service (LG LDF6810xx) for the dreaded LE error code we checked the wiring in the door per this thread. Sure enough a black wire completely broken in half and a red one with the insulation off. The black wire was completely embedded in the sound deadening material such that it was hard to even spot it at first.Anyway, simple fix and lots of money saved. Thanks to all.
