We've replaced the motor and pump due to not pumping, then the water inlet due to leaking, we are still getting an LE code and there doesn't seem to be a leak sensor like Samsung's. Any thoughts?

I realized that LE is the motor or main PCB.

Le means main control board doesn't sense the motor turning

Well you've replaced the motor.  I assume you've checked connections, and eliminated any restrictions that would keep the motor from turning. Looks like your down to the board. The manual gives instructions on testing.

Did you replace just the vario motor or the entire sump assembly?  http://www.repaircli...umber=LDF6920ST

 

Have you checked the wire loom inside the door for breaks caused by sticking to the sound dampening goo?

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

 

What is the Serial Number---and the Part Number(s) of the components that were replaced?


Edited by john63, 31 August 2013 - 11:02 AM.

To eliminate:

Musty odor

L-O-N-G cycle times

Dingy/yellowing whites

Suds error message

Slow spin speeds

Intermittent water leaks (from rear of washer)

And other annoying symptoms which vary brand-to brand.

Read below:

The *correct* amount of HE (High Efficiency) detergent that should be used in any front load or agitatorless top load washer with tub sizes 3.0 cu ft and larger is as follows:

HE: (2) Tablespoons Per Wash Load

HE 2X: (1) Tablespoon

HE 3X: (1) Teaspoon

Perform a TUB CLEAN CYCLE every (4) months.

Use: "Tide Washing Machine Cleaner"

We replaced the entire sump assembly. Ordered another one just in case because it wouldn't be the first time we got a bad part from Marcone. Also ordered the main pcb to cover all the bases. All connections were checked nothing broken or corroded

Should be able to check voltage at the pump. If you have voltage there then it's a bad assy.

Uhh...wait a minute..... Have you checked voltage at the junction box? Connection on the white could be loose. Need to make sure you have 120v between the white and black there coming in. Could have a bad neutral.

<<<We replaced the entire sump assembly>>>

 

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

 

Verify that the Wash Motor plug is *connected*---it can easily be overlooked/forgotten.

 

Can be checked by removing the lower kickplate and insulation material. Use a flashlight to inspect the connection to the Wash Motor.

 

Sump Assembly part number should be (AJH31248604).

 

Leave the Soil Level /Turbidity Sensor *unplugged*:)

 

NOTE:

 

All LDF6920 dishwashers have the *cloth-type* insulation within the Door Assy---eliminating problems associated with older LG model dishwashers having damaged (pulled apart) wire(s).

 

LG dishwashers built around 2007 and older were prone to failed wiring (from insulation).

 

What is the SERIAL NUMBER of this dishwasher???

Uhh... ignore my statement above. Obviously the neutral is ok or you wouldn't be getting a code. So, sorry.

The Serial Number is still incorrect---should begin with three numbers and then four letters---followed by more numbers.

 

Has the Wash Motor plug been inspected?
