Am I using the wrong kind of detergent?

This error code indicates excessive detergent suds occurred during the cycle. This could be caused by using too much detergent or not using High Efficiency (HE) detergent.
The washer will not be able to spin out water with the excess suds. When "Sud" or "Sd" is displayed, the washer automatically extends the rinse time to remove the excess suds. During this time, the washer pauses the tumbling and adds water for additional rinsing. This pause allows the bubbles in the suds to break. This pause and rinsing are necessary and may occur several times to eliminate the suds. This could significantly lengthen the time for your washer to complete the cycle.
If the problem continues, and the correct amount and correct type of detergent is being used, we suggest running a "Clean Washer" cycle to remove residual detergent that might have built up in the washer. Follow the instructions in your Owner's Manual for cleaning

Maybe your water is very hard. Might need a softener...

The SD error code is caused by using the wrong detergent or excessive amounts of detergent.

To correct the issue: Make sure to use HE detergent. Note: Using Non - HE Detergent will cause oversudsing and can damage the washer. Do not use too much detergent.

Note: If using HE 2x - 5x concentrate detergent, reduce the amount being used. The washer will try to run a mini-clean out cycle using cold water and a 5 minute pause to clear the suds. If this cycle does not clear the display and complete the cycle the clothing may need to be rinsed by hand and then rewashed without detergent.

Hi
White film deposits are observed if water is hard or when you are using more detergent than needed, try filling detergent cup half way. Try using white vinegar after the wash cycle is complete, run a complete cycle. Also turn down the heat on the hot water fed to the dishwasher. Try using water softener for better results.
You can also add vinegar in the final rinse cycle. Make sure that your soap dispenser drawer is opening and closing fine.
Hope this helps... Please post back if more information is required.

You might try a cup of white vinegar added to the final rinse cycle...with NO LAUNDRY in the machine. Just turn the dial to rinse. Let the machine fill. Add one cup of white vinegar. Allow the rinse cycle to complete. The vinegar will help to break down mineral buildup that might be causing the grunge.Also, have you changed detergents recently? Could it be the water in your area reacting with a new detergent?

Mine has been doing the same thing for about 2 months now.. I tried Finnish brand diswasher cleaner, but to no avail. Try this:

1) Empty your dishwasher, then take out the lower rack.

2) Start a regular cycle. Wait until you hear the jets turning, then open the door. Make sure there is enough water in the bottom - It should be just UNDER the heating element.

3) If your dishwasher is getting enough water, Reset your washer and allow it to drain.

4) Go to the store and get a gallon jug of white vinegar. Start your dishwasher on a regular cycle.

5) Once you hear the jets turning, Open the door and add FOUR CUPS (liquid measure) of white vinegar to the water in the bottom. Let the wash cycle complete.

6) When the wash cycle drains, the rinse cycle will fill. Once the rinse cycle starts, add ANOTHER FOUR CUPS of white vinegar to the first rinse cycle.

7) Allow the first rinse cycle to drain. Let the second rinse cycle complete normally.

I know this sounds too good to be true, but it REALLY DID work for me, this evening as a matter of fact! I also bought some hard water/soap film detergent additive from the store. It was kind of expensive, but I'm using it for a while just in case.

I hope this helps. Like I said, I couldnt believe it when my dishes came out clear again! Also, I turned OFF the heated dry cycle, and just opened the door and pulled out the racks when it was done.

Good Luck!

Try to fill minimum water level in your machine with out adding detergent or clothes and complete cycle and see if it is any watter inside. Could be a water pump.

You will need to have a qualified LG technician come out and see what the problem is.  You may have a water level switch issue.

As far as using the vinegar, this should be complete when there is NOTHING in the dishwasher. The idea is to remove the build up inside, not clean the dishes. Make sure to use only White Vinegar. Also, changes in the water of any kind can cause a build-up. Try using a little less detergeant and rinse.
