I am trying to determine exactly which main board part number I need for an LG LDF7810ST serial 511KW00949.  I know there are several types but I cannot find anything below 600 on the serial number to correlate.  My board has gone bad but the company now states they can no longer get the board and I need to know the board number to search for an alternate source.

Checking...

 

It'll take about 30 minutes before I get info---stand-by...


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"

Main Board: Part number: 6871DD1014C

Part number: 6871DD1014C

 

 

I cannot find any supplier---that has this board in stock.

 

I'll check my inventory tomorrow.

 

Probability that I have one in stock is 70 percentile...

Sorry for the wait---been a long day.

 

You're in luck--I have the Main Board.

 

Send me a PM---with your phone number. I'll have the office arrange payment/shipping ($118.00 + shipping)

Sir,  I did find a service bulleting here and it indicates a manufacturing period 511 machine like mine used a 6871DD1006C which is interchangeable with the 6871DD1006G.  When our recent service tech visited he ordered a 6871DD1006G and they subsequently said that part was no longer available and therefore the machine needed to be replaced (which is not an option right now). I know you indicated the 6871DD1014C was the board but I just wanted to bounce this off of you.  I can get a 6871DD1006G and perhaps the best approach is to buy the 6871DD1006G and the 6871DD1014C and see what is in there when I disassemble it.  I welcome your thoughts.

<<< I can get a 6871DD1006G and perhaps the best approach is to buy the 6871DD1006G and the 6871DD1014C and see what is in there when I disassemble it.>>>

 

**********

 

No need to compare---order the *correct* Main Board (Part number: 6871DD1006G

Part number: 6871DD1006G

)

 

The original Main Board for your dishwasher does *not* have a HEATER RELAY 

 

 

These are the images of both Main Boards...

 

Part number: ap4457388

Part number: ap4457388

 

You've done your homework!

The following image---is the same as on LG's website (parts look-up)

Notice the small chart which shows a caution when ordering the Main Board (location number K251)

Normally---if there are older models (but not shown/listed)---in this case "601" (January 2006)...

There will be an image of this...

 

~601

 

The LG website chart shows...

 

601

 

Little things matter.

 

If you look at the Service Bulletin again---it includes the full listing for older models---beginning with 501 (January 2005) through 512

 

The 6871DD1006G and 6871DD1014C Main Boards are *not* interchangeable.

 

Good Catch :)
