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.
