lg6920st he error 001kwfno1923 dishes not clean soap on door *have not been using rinse aid. pump/ sump assembly or pcb?

6 posts in this topic

Hello all we bought lg appliances for our kitchen 2 or 3 ears ago. lg 6920 st worked pretty well despite not using rinse aid over this time. Recently its been cleaning poorly and after running the diagnostic tests it developed an he error. serial# 001kwfno1923 dishes not clean, soap on door *have not been using rinse aid. pump/ sump assembly or pcb? not sure which i should purchase. the repair person lg sent us to said buy a new machine by the time i get there and replace the sump assembly etc. but if you are getting rid of it I will buy it. I now know after reading up I should be using rinse aid and either powdered soap or finish powerballtabs. We had been using some 7th generation hippy soap when this prob developed then target tab things . some white build up in the base area arms/jets seem clean. I want to take a stab at it before buying new if any one can advise which part is the best guess I appreciate any help! thank you. cec

<<<Recently its been cleaning poorly>>>

 

 <<<dishes not clean, soap on door>>>

 

*********

 

LG Dishwasher

Model: LDF6810ST

Serial: 001KWFN01923

 

Caused by a fault in the GUIDE ASSY (4975DD1001A)

Symptoms include---poor wash and water leaking from the door.

 

NOTE: When ordering replacement Guide Assy---call the parts supplier for *verification* of Build-Date on the new part.

Date Code on the replacement Guide Assy ***must*** indicate/show DECEMBER 2010 or later.

The Guide Assy part number has *not* been changed---only the Date Code is used to identify original/older flawed Guide Assy from newer/revised Guide Assy.

 

**********

 

<<<it developed an he error.>>>

 

**********

 

Caused by a software glitch in the original MAIN BOARD (6871DD1006P)

 

Replace with revised/corrected MAIN BOARD (6871DD1006R)

 

 

 

Additional Info...

 

If the dishwasher has made whistling/gurgling/growling noise *during wash*---replace the CHOPPER (5832DD4001B) which has been re-designed.

 

As an option---the FILTER ASSY can also be replaced with an updated version---to minimize the potential for debris (toothpicks/glass shards etc) entering the Sump Housing during the wash cycle.

 

The part number has *not* been changed---order the Filter Assy by BUILD-DATE.

 

FILTER ASSY (ADQ32598202)----Built *after* September 22, 2012

thats right its a LDF6920ST  ran it again HE error code. at the end there is water in the bottom. If i go through the tests it will drain water. when i ran through the diagnostic tests i did smell some hot plastic/electrical smell at the heater spot never ran it for more then 10 sec as the service manual states. After that we got the HE error.  I have read that replacing the pump assembly has worked in some cases others say i need a new computer. the repair guy we talked to said he would do the pump assembly first and if that did not work then he would do the computer. i will look into te errors in the mean time. the post above is a different model but same serial number should i order the same parts? i am reading it needs a new main board and guide assy? as well as a new chopper. It fixing this even a good idea? There is a lot of neg lg posts. I appreciate the help!

Sorry---that's my mistake.

 

Oftentimes when I am on this forum---I'm doing paperwork/claims/parts orders etc.

 

I happened to be processing info on an LG 6810 dishwasher while posting about *your* LDF6920 model.

<<<its a LDF6920ST  ran it again HE error code. at the end there is water in the bottom>>>

 

**********

 

When an "HE" error has been triggered---the dishwasher will stop working.

 

If water was in the tub at the time of the error---it will remain in the tub.

 

This is caused by a Main Board software glitch.

 

If the temperature of the water---during MAIN WASH or FINAL RINSE exceeds the *target temperature*---an "HE" error will be displayed. The dishwasher will shut-down.

 

The revised Main Board---does not see/recognize an overshoot of the *target temperature* (by a few degrees) as a fault/problem---and allows the cycle to continue if the water temperature is slightly above target.

 

Replacing a SUMP ASSY on an LG dishwasher built January 2010---would be a *waste* for the symptoms you've described.

 

Replace the GUIDE ASSY as well...
