Question about LG 24 in. LD-12BW5 Free-standing Dishwasher

Open Question

Dishwasher (LG Inverter Direct Drive - 2 years old) sounds noisy (never used to be) like it is grinding or groaning. The dishes are not being cleaned and come out greasy and spotted with food. There seems to be no real constant washing now - just stop, start, stop, start. When I open the door midcycle the water arms have not moved and the upper shelf dishes are barely wet. Any ideas?

SOURCE: LG LDS5811WW Low pressure out of spray arms

On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.

But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.

If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.

Watch for error codes on the display and report back what you find, OK?

Good Luck!

SOURCE: LG Dishwasher redepositing debris back onto dishes

Have had a problem with our LG 5811 Dishwasher not operating.
I have found the Vent Hole Cover located inside the Door was not installed correctly. I used plumber putty between the plastic fitting and the inside face of the Door and turned the Cover fully to lock in place (vent hole is toward Door bottom). Water was leaking previously from this opening over the wires in the door.

Another problem was the lower Door Seal (under the Door) it was not installed correctly either. It was actually too long and would not seal against the bottom of the inclosure. Water was coming out and spraying the wires in the door. I had to remove the metal stiffener over the front of the Dishwasher to get to the Door Seal. I removed one end and reinstalled the seal. The Seal laid flat but was approximately 3/16" to long. I cut off the end with a sharp knife - seems to be the correct length now.

Try these things in order:

-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?

Our LG is only a couple years old and was very quiet at first. It has started making a very loud groaning noise when the water is spraying. Is it a pump going out?


Hi

In Australia I have seen similar problems with some recent models of LG dishwashers. Not sure if the ones sold in the US are any different.
One common problem I have seen with LG wash pumps from dishwashers which were sold 2-4 years ago, is that the motor becomes noisy after some time. The replacement motors which I have ordered is a different one and therefore revised as the predesessor was not reliable. The replacement motor has a different mounting bracket as well.
They are fairly cheap, but to change them is very difficult. Best to get a repairer as the machine needs to be thoroughly dismantled to allow you to get to the wash pump.

Hi I have a 2 year old lg LDF7920ST Dishwasher... It started leaking out of the bottom about 3 mths ago. Now it makes a load grinding sound when attempting to wash dishes...


There is a drain in the evaporator (inside the door) that has a black tube that is clogged in the tube or where it connects. Food or soap scum can clog it and the water will flow down the white tube to the floor. Remove the screws form the door and then clean out the tube and nipple part.11_16_2012_6_15_43_pm.jpg

Load grinding noise, like the engine is working too hard.


Most likely the motor/pump assembly is worn out and grinding. If the machine is less than five years old it is under warranty. If over five years old, the repair part alone is about $150 not including labor.

How do you fix a noisy whirlpool dish washer DU1100XTP(Q) ?


A hard object has entered the wash module (on some models).
When the object is ground up, the sound should stop. If the
noise persists after a complete cycle, call for service.

RESIDUE ON DISHES-NOT CLEANING WELL-DETERGENT NOT DISSOLVING-LONG CYCLES


Sounds like you have motor pump problem and may need to be replaced.  The parts are covered for 2 years but you'll have to pay for the labor.  Call a qualified LG technician for service on your dishwasher.  You can find them on the LG website.

GE Adorda dishwasher


This one is a known issue and an easy fix. Use a tie wrap to securely tie the water tube for the middle spray to the upper basket. That's it. Believe it or not, it's that simple. You may want to secure it at the front and the back. To test this you can use the tie wraps used to closed the plastic grocery or bread bags. If this solves the problem you can buy a bag of nylon tie wraps from any hardware store. I had a similar problem with another GE model with a similar problem. The dishwahser used to make a horrible grinding noise during the wash cycle. One I secured the middle sprayer arm the grinding noise went away.
