Our 3 yr old LDF6810ST has been giving poor results lately. Up to know it's been a great dishwasher with no problems. I downloaded the service manual and when running the Check Program I get:
Upper Only + Time Delay + Power: results in 3H / U3 (manual = 3H/U2)
Press Time Delay Once: Result is 2 / 40 (manual = 31)
Press Time Delay 4 times: number scroll from 1 -99 (manual = 34)
Press Time Delay 9 Times: Result is 20 (manual = 39)
I am leaning towards the heating element being bad. Has anyone else had similar problems and a good result with replacing the element?

If you're sure you're using enough soap, check that your hot water is connected and that you're using a hot-water wash (some dishwashers have a cold-water option, this will often give unsatisfactory results if washing greasy dishes - especially beef fat).
Check if the water is getting heated in the dishwasher. Most likely water temperature if not adeqaute will not fully use the detergent and cause dirty dishes. This could be caused by heater which is failing.
Their are quite a few reasons for a dishwasher to have white residue on your dishes. I will list some steps to take and help you get your dishwasher working again.
1. Are you low on Rise Aid?Most dispenser have a 1-6 setting right under the cap. Make sure your set between 3-4 for the best results. This additive helps in cleaning and drying your dishes and most manuals will say its required for best results.
2. What type of detergent are you using? If you are using the dollar budget type product you will get very poor results. If you are using a name brand make sure it does not have rise aid already included. Too much rise aid could cause white residue as well.
3. Do you have hard water?Hard water can make it more difficult for your dishwasher to clean. Be sure to use a dishwasher cleaner such as Dishwasher Magic at least once a month. Your dishwasher does a great job at cleaning dishes but when it gets dirty it needs a little help.
To save energy, the LG LDFx810 dishwasher product family does not turn on the heating element during the drying cycle (third blue light blinking) rather it brings the final rinse water up to a high temp (I think it is 160 degrees (f)) and then uses a condensing drying system (mounted in the door) to pull the wet, hot air from inside the dishwasher. When it works, the dishes come out pretty dry (except for some plastics)
Check this: -When the DW does its final drain, confirm that the water drained into the garbage disposal is really hot and not just warm. Be careful to not burn yourself and use a meat thermometer if you have one.
- After the water drains for the final time and the dishwasher blinks the third light, put you hand under the left hand side of the DW door. There is a slot down there that should be exhausting warm air.
If either thing is not happening, it is time to get a professional to check things out and make repairs.
Please post back here with what you find or have further questions, OK?
-Try to use a name brand powder, rather then a generic. Even a small box. I had similar problems with my LG dishwasher when I tried to save money by buying a generic powder. My dishes did not get clean and white marks were left behind on my stainless steel DW liner and the dishes. When you ad the powder, do not over fill the dispenser. Add less than the full dispenser cup and close it. Place some powder in that shallow square indent on the dispenser lid to help the pre-wash cycle. Also, run the water in the sink until hot water runs immediately before you start the DW.
-If, after using Electrosol or Cascade for 2 - 3 loads and your dishes do not come out clean, then I would run a load of dishes without adding the soap. Start the dishwasher and wait for it to fill and begin to wash. Open the door and add one cup of vinegar (white vinegar is fine.) Feel free to ad another cup after the first wash water drains and the second wash water enters and the DW begins the wash cycle again. Run a load of dirty dishes with the soap and check for good cleaning.
-If the problems continue, it is time to remove the filter assembly by removing the 9 silver phillips screws from the filter assembly. You will also need to remove the lower sprayer arm by pulling straight up and then out. With a flashlight, inspect the sump area that was hidden by the filter assembly, looking for any debris that has jammed into anywhere down there. Watch out for broken glass as you feel around. Reassemble and test with a load of dirty dishes.
The poor drying may be caused by not keeping the rinse aid re-filled. Check that first.
Also, these water and energy conserving dishwashers actually use the "dirt" from the dirty dishes to help clean the dishes during the first two wash cycles. Simply clear the big chunks off the dishes and put the dishes in the DW.
Please report back what you find or if you have more questions. OK?
is the salt container cap damaged or loose? is the rinse aid topped up? if all ok then are you scraping most of the food from the plates, this can cause old food to mush, pulp and leave grit on dishes.
ok ...first the average dishwasher will only heat the water 1 degree per mintue,,,now if your starting out with very cold water the dishes will never get clean check your water temp,,at start up..if you have 90 to a 100 degrees thats ok..that means we have problem in heater circuit...also turn up your jet dry level...keep me posted onthejob,,incase we have to look at heater circuit
It is very common that high eficiency, low water using dishwashers take longer to finish all cycles. The best way to "hurry" the washing is to make sure that the water heater is providing hot water of at least 120 degrees. But no hotter then 140 degrees.
If the dishwasher runs even longer, check to see is the dishwasher is actually connected to the cold water line. This dishwasher can be run from cold water but the water heating phase in the cycles will add much time ti the entire cycle.
This unit has a sensor that detects the detects the water clarity towards the end of the wash cycle. Rinsing the dishes may speed the load a little, but encourage not to go crazy on the rinsing because the dishwasher actually counts on the food particles to help clean the dishes.
Also, note that the final (third) blinking light means drying. You can simply open the door anytime after the final draining and power off the dishwasher, allowing the hot dishes to air dry.
Hope this helps. Please resply with your findings. Thanks!
