LG dishwasher LE error code

10 posts in this topic

I have an LG dishwasher LDF6810ST that keeps displaying the LE code. I have read many posts on here with similar problems but all seem to have had luck with either the wiring, sump assem., or main board. I have replaced the sump assembly and the main board and have the checked the wiring as well. The dishwasher will kick on for a few minutes before showing the LE error code. Any suggestions would be very helpful.

 

thanks.

Howdy, EE.  A couple of questions for you:

 

- Did you replace the sump assembly with a new one?  Lotsa folks buying used parts these days.  Not sure why, doesn't make good economic sense to me.  

 

- When the dishwasher kicks on initially, is the water actually being sprayed or is the vario motor just hummmming and then kicking out?  If the latter, the motor is either stuck, something's jamming it, or maybe the sump assembly is mis-wired.  

 

- One of the wires in the door wire loom may be broken but not visibly so.  You need to ohm out each one.  

 

You can review your work by singing along with my seminal video on this problem:

First of all thank you for the quick reply.

 

- I ordered the part via amazon and it was marked as "new" so it better be.

 

- When the DW first kicks on the water will drain and fill with no humming noise but the sprayer (which I believe is controlled by the motor) will not kick on and this is when the LE code is displayed.

 

- And what would be the easiest way to ohm out each wire?

 

thank you.

Parts from Amazon are notoriously either generic knock-offs or used.  Read about my horror story with Amazon parts:  http://ymlp.com/zsTPYA

 

 

Never again!

There is no easy way, just the PITA way:  end to end continuity check on each wire in the loom.   :wacko:

Okay, well lets assume the sump is fine as well as the wiring. Is there anything else that could be causing the problem?

 

And if you don't mind could you suggest a reputable website where I could order the sump or any other part in the future?

 

thanks.

Did you physically check the wiring in the door to make sure it's not broken in the "tar" like mastic sound insulation?

No, for this problem, sump assembly and wiring is it.  You could try turning the wash impeller blades by had.  But that's the root cause of the error:  the hall sensor is not detecting movement of the wash impeller.  

 

 

And if you don't mind could you suggest a reputable website where I could order the sump or any other part in the future?

 

 

 

I thought you'd never ask!

Scott, yes I have taken off the front panel and bottom plate and checked the wires quite thoroughly all the way to the bottom. No visible signs of damage.

 

Samurai, thank you for all your help thus far, I read your link about amazon parts and I did not see any logo on the shipping box. Is there any other way to make sure this is in fact an OEM part? Such as looking up a part code on the sump?

 

Thanks.

With previous sump the DW would not turn on without resetting the breaker. With new sump it will turn on like normal but then after a few minutes display LE code.
