SOURCE: The filter assembly in my LG dishwasher is always getting dirty.

Hi Jim,
Make sure that all the spray arms are clean and not blocked firstly
Pour a half a cup of white vinegar straight into the bottom (sump) of the dishwasher and run it on fast wash.
The vinegar has a small acidic base which breaks down fats etc.
This may fix the problem, or there could be another problem. It would be hard to tell without looking at the unit itself.

SOURCE: dishwasher leave debris on dishes

there is no filter except the screen in the water inlet valve to keep big pieces of grit in the water from defecting the inlet valve..
i dont know exactly why but it sounds like your unit was not installed with a recommended air gap in the drain or something similar and somehow dirty sink/drain/sewer water is making its way back into the unit and onto your dishes.
often times there is a little rubber check valve/flapper in the drain line either installed in the pump or the drain hose just after the pump to keep foreign material from entering the unit..
other than that it would just be mineral and calcium deposits if you are on well water or chunky city water..
hope this helps,
best of luck,

Dishwasher not cleaning properly

There are many reasons why a dishwasher does not work correctly. A repairman told me to always check for debris (food, coins,lids, hard things lost in the dishwasher). You can take the screw off the arm that turns on the bottom level and search under there for anything stuck (even pieces of bone) the dishwasher has several other food filters in the motor assembly but this first one is easy to get to. I would let a repairman fix the motor, but as he said this easy fix is a possibility.

Hello, LG LD 14AT1 dishwasher, starts cycle runs 3 minutes, starts stops on off no water in bottom. Then displays OE chimes! Checked tap under sink water there, checked filter inside bottom, turned off for...


OE in your dishwasher is a drain error and dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. If the issue returns after cleaning then the drain pump assembly should be replaced. Hope this helps...please post back for further assistance.

I have a LG 4821st dishwasher and it comes up with an E1 error code. Have not been able to solve

This code is for a "leak" that the system's computer is detecting. Let me guess...Does the system make a groaning noise like it's not getting enough water? Here's what you should do...First, pull the lower dish rack out and thoroughly clean the filter. If you're easily able to remove the filter, do so and continue to clean. Also look for any debris under the filter assembly. A final step to completely make sure all of the water lines are clear of debris, you'll need to remove power, pull the washer out of the cabinet, and then (carefully) tip it on its right side. Next, remove the two plastic assemblies that are on the left side and remove them from the dishwasher you will need a vice grips to remove the hose clamps from behind them, you will also need to remove the round circular water intake plastic disk that is on the inside of your dishwasher on the left hand side right in the middle of the left wall and clean them. Once the water can run freely through these plastic parts you will get a good water flow and you should be fine. It's a bit of a task, but not too difficult. To minimize this from happening in the not-too-distant future, you may want to ensure that you're not putting too many dishes in that contain heavy, solid food debris. Also, I recommend using the Finish brand tablets instead of heavy liquid detergent. It not only is more cost-effective, it also does a wonderful job and won't build up in the water lines of your nice dishwasher.

I hope this helps and please feel free to ask me if you need any further assistance!

Take care and have a WONDERFUL holiday season!

LG dishwasher is whistling a high pitch tune during washing

It is difficult to be specific without knowing the model number of your LG dishwasher.

On newer LG models, the most common cause of noises is from debris stuck in the lower filter assembly area. Recommend you remove the lower spray arm and the screws that holds the filter sub-assembly in. After removing the assembly, inspect with a flashlight to search for any debris that is jammed in that area. Also rinse out the filter as best possible to remove any thing you see in there. Reassemble and test.

After cycle completes there are small pieces of debris over the dishes. I have ran the dishwasher cleaners through but no help.

The LG LDF7811 Dishwasher is a water and energy conserving unit. So, anything the obstructs the wash pump reduces its ability. here are some steps to follow:

1.) Buy a box of brand name dishwasher detergent powder (e.g. Electrosol or Cascade) Use it and avoid generic powders and never use gels or tablets in any dishwasher.)

2.) Remove the lower basket and then the lower spray arm (pull it up and out firmly)

3) Remove the approximate 9 phillips screws from the filter assembly beneath where the spray arm was. (Take a digital picture of each stage, so you can reassemble later.)

4.) Rinse/wash everything, especially the filter "orb" with the mesh panels, as best you can.

5.) With a flashlight, inspect the sump area that you just exposed. Watch out for broken glass! Remove all debris and look one more time for any little chunks that may be blocking stuff down there.

6.) Inspect the impeller, looking for damage, being plugged. Make sure it spins freely, but is also securely fastened to the top with the screw.

Reassemble the dishwasher and test.

Please report back with what you find. OK?

Thanks and Good Luck!

Noisey pump

Take the drain pump apart and look for debris, or broken pump impeller. Remove the lower spray arm and filter assembly, check for debris in the sump and check the drain check vavle to make sure it is sealing properly. While in there make sure the food disposer blade are not clogges with debris.

Dirty dishes on lower rack

Please confirm that you own an LG LDF7811 dishwasher and it is not cleaning properly.
-Are you getting any error codes displayed? -Did you remove the mesh filter and clean any debris beneath it plus rinse out the filter itself?
-Are you using a name brand diswashing powder? Avoid ultra-cheap detergent, especially in water-conserving units like the LG 7811. Never use DW gel or tablets in any dishwasher.
-Do not over rinse the dishes before placing them in the DW. The food granules actually are used to clean all the dishes before being rinsed away.
Please try these suggestions and reply to this message with what worked best and if the problem continues. Good Luck!
