Patrick, With the sump assembly having been replaced and wiring to the sump checks ok, then this issue will be caused by a faulty main control board EBR38144406.

Kazper for Model Number LG dishwasher ldf6920st

There are a couple things going on with my dishwasher. First, the top rack of dishes only cleans some items. Many times there is residue left on the dishes. I rinsed all of the arms (twice) and cleaned out gunk that was in the sump assembly area. The problem continued. One repair person mentioned that our water might not be hot enough. We always run it for a few minutes until it is hot before starting the cycle. The other thing is that the washer makes a rather loud grinding noise during the cycle. It seems to come on roughly 5 minutes after it has started and continues until the end of the cycle. I am wondering if this suggests a new sump assembly is needed and if you believe that would solve both problems.

Kazper, Based on the description, the issue sounds like it may be a bad diverter motor which turns the check valve and switches the water from lower to upper. The part number for this will be 4681ED3001D

Hello Jeff, This is the error code for an abnormally operating motor assembly. If there is nothing restricting the rotation of the motor and there is no clog in the drain line, replace the wash motor 3485ED1002B. If the problem persists after the wash motor assembly has been replaced, the PCB 6871DD1006G has failed. I'm sorry but this part has been discontinued by the manufacturer and no satisfactory substitutions have been provided.

Studioxyz for Model Number LDF7811ST

Hi My dishwasher started reporting error OE (drainage problem) and some research revealed that replacing the sump assembly is somewhat of a catchall solution. I replaced the sump assembly and ran the dishwasher to test the fix. It still does exactly what it did before replacing the parts. The first cycle runs but the error presents when moving on to the next. The drainage hose is clear (I can blow through it to force water into the garbage disposal) so I'm not sure what to check next. Any ideas?

1 Answer

Studioxyz, You will want to check for power getting to the drain pump. If power is not getting to the drain pump then you will want to check the control board for sending power. If the control is sending power then you would need to check the wiring and if not then replace control board.
