[dougieb44]

have a lg ldf 6920  flashes HE on the display ane stops running during the final rinse cycle

[krazytech]

1. unplugged the dishwasher from the wall  ( hard reset)
2. Run hot water at the sink faucet  (too make sure Hot water enters the dishwasher)
3. If HE error returns
    a. Check for Broken/loose wire from control. (in the door panel)
    b. Ohm the Heater element. (check for open heater)
    c. Ohm the thermistor (check for out of range reading)

[wildimaginations]

If everything checks out up above, replace the control board.  There is a program defect and the only way to resolve it is to replace the control board.

The LDF6920 model dishwashers do *not* have the sticky/tarlike insulation material.

Is the part ending in Q, not the newest John?

[john63]

All of the following are interchangeable...

6871DD1006R
6871DD1006Q
6871DD1006U

All have the software correction for the "HE" error.

[dougieb44]

original part was 6871dd1006U
replacement was 6871dd1006Q

will replacing the board with 6871dd1006R fix the problem or should I be looking elsewhere ?
