All LG 6810 dishwashers had flawed WASH MOTORS.

Replace the entire SUMP ASSY (AJH31248604).

Many non-LG parts distributors still sell the older (also flawed) SUMP ASSYs.

If you decide to order only the WASH MOTOR---there's no method of determining whether or not the motor is the *improved* version. Not worth the risk.

************

<<<When I got down to the impeller it would turn, but instead of a smooth spin it felt very gear like.>>>

************

An indication of a failing WASH MOTOR (chirping/grinding noise during wash).
The WASH MOTOR begins to "degrade" over time and runs at a slower RPM (poor cleaning).
Eventually it runs slow enough that the computer triggers an "LE" error.

Other problems with the earlier LG dishwashers (built before May 2008) were:

1) The insulation/sound deadener on the DOOR caused wiring damage (pulled apart)

2) The VENT/DUCT inside the door was too small and also "directed" condensation back into
    the tub during the DRY CYCLE (it's now vent to the atmosphere)

3) The DRAIN HOSE was redesigned in later models to prevent *siphoning* of wash water
    during a cycle. If not installed correctly---the 6810 dishwasher can "lose" wash water and
    trigger an error message of: "1E".

************

<<<Don't even ask about my LG fridge that almost caught fire.>>>
<<<I was lucky, but others weren't.>>>

************

A problem found in many LG French Door refrigerators built within a specific time frame (certain model years).

While it is common for me hear (justifiably,I might add):

"There could have been a fire"
"I was worried that the refrigerator might burn-down my home"

I am not aware of a single incidence of a report or claim that a fire occurred in an LG refrigerator due to light bulbs being "stuck-on" with the doors closed.

No recall has been issued by the Consumer Product Safety Commission (CSPC) nor from the Canadian equivalent.

During an investigation by the consumer protection agencies---it has been labeled:
"A low-risk for fire hazard".

LG has offered a lifetime warranty for any & all repairs needed (parts & labor) to correct this complaint/failure (caused by a "frozen" relay on the MAIN BOARD).

The wattage of the lightbulbs were not excessive---nor did the MAIN BOARD "send/deliver" too much current/electricity to the lightbulbs.

The replacement lightbulb housing contains a THERMOSTAT---which will shut off the lightbulbs if they remain "on".
The new relay on the MAIN BOARD is much larger and less prone to failure.

Thanks for all of that info on the DW.  I will take your advice and look into the newer assembly.

As for the fridge, when I did call LG that day the support tech said there was an internal recall that superceded the warranty time.  I didn't argue with them, as I was happy to have the repair.  I was suprised to find two 60 watt clear bulbs in the housing.  Why would someone need 120watts in a fridge?  They assured me it was fixed, but I removed the two bulbs and installed one appliace bulb.  I fell better now.

I took John's advice and purchased the newer assembly and it was different from the factory part.  It seems a sensor (M087) moved from beside a small motor (M026) to the front of the unit by itself, so I had to reroute the wire in the harness.  Oh and the rubber seal around the unit was a much better design in my opinion.  The original only had the top area (visible in the DW) and one thin rib just below it to help hold back the water.  Judging by my floor and the area below that it had been leaking before all of this.  The new rubber seal is thicker, and had at least 4 or 5 ribs below the top area.  I'm sure it will help with leaks, but it sure made installing the unit difficult.  I was sure I was going to bend the frame trying to get it in, but it didn't thankfully.  I had forgotten how quiet the unit should run.  I had the DW on my back patio and let it run there last night.  I bought an adapter to hook the water line to my garden hose and used an old three wire drop cord to plug it to the receptacle.  At first it thru an E1 code after 15 minutes, which the manual said was a water leak detection.  I remebered from a post on here that this unit required the drain hose loop to be above the vent.  The original 12ft drain hose split last year and I used a universal replacement hose and looped it under the counter.  On my paito I just set the hose on the patio, so taped the hose to a patio chair to elevate it and that fixed that issue.  It ran fine last night and I started it again this morning.

Originally when I was going to just replace the moter, impeller and gaskets I was looking at $110 plus shipping.  The entire unit plus shipping was $164 from repairclinic and it came with the better motor per John.  The replacment unit with the original motor design is $186 before shipping.

Hopefully this unit will be fine for a while and thanks so much to everyone who helped.

*********

The TURBIDITY/SOIL SENSOR was relocated to the *front* of the dishwasher.

It's best to leave the sensor ***unplugged***.
Doing so---will improve washability results---by eliminating a feature of the "computer" that is monitoring the state (or condition) of the wash water during the cycle.
This sensor can ***reduce***total cycle run time (sometimes too agressively).
Disconnecting the plug from the TURBIDITY SENSOR allows the selected cycle to run in it's entirety.
NOTE: Removing the plug from the sensor will NOT trigger an error message.

NOTE 2: The plug can be disconnected from the sensor by simply removing the lower KICKPLATE.
              May need to use needlenosed pliers to reach it.

Applying a thin coating of SILICONE GREASE to the stainless steel lip of the tub---allows the SUMP ASSY to be installed effortlessly.

Good job on your repair :)
