    there was a small amount of debris...nothing much to speak of, the filter housing has 2 orings that are located on it, one had come off and they seem to be soft and somewhat squished..LG doesn;t list these seperately and one would assume that they are part of the filtermesh housing, there is an oring beneath this by the sump..it appears to be loose fitting(it is a weird shape..not round) would you advise on replacing this at the same time...or should I put it back together for a test run before I order parts...thanks.

Vicky,

I understand that your LDF8812 fills with water (and drains?) but is not cleaning and you are not hearing the unit wash. Are the dishes on either rack getting wet at all?
-Are you getting any error codes in the display?

On LG dishwashers, the upper and the lower arms never spin at the same time. Rather the vario check valve routes all water pressure either up or down.

The arms turn because the wash motor turns the pump (impeller) which drives the water to/through the wash arms. If the wash motor was faulty, you almost always get an error code. So the problem is probably caused by a blockage of the "plumbing" in the sump area beneath the lower wash arms. But first check all three wash arms to confirm that the holes are not blocked. (How cool is it that the light inside this model helps you do that?)

Next use a screw driver to remove the filter assembly in the sump area. There are 10 screws to remove, but first you need to firmly lift the lower spray arm directly up and out.

Inspect the entire sump area for debris. Watch out for broken glass! Look closely at the white area near the back for blockages at the check valve.

Please report back what you find and we will take the next step. OK?

    Replacing the O rings would be a good move before going further.

    Also, confirm that the impeller is tightly attached and spins freely.

LDF7932ST LG dishwasher top and bottom arms not turning. Diagnostic test mode "power+spray+ rinse" does not work.


I put a new lower spray arm and very little water comes out of it. There is quite a bit of water that comes out of the middle and top. The top does not spin but has quite a bit of water and the middle spins really good.

The spinner on top of the dishwasher, that I guess shoots out the water is not spinning. I think?


You may have debris in the sprayer arm jets. It is usually simple to remove the sprayer arms. Then rinse them well using the sink sprayer for forceful water power. I have sometimes had to use a tweezer to remove bits of plastic, paper, bone, or food particles. Once you've remove the debris, rinse well forcing water through to dislodge any other debris. Once you've reattached the sprayer arms, you should have cleaner dishes. Also, some brands of dishwashers have a pipe that runs up the inside back wall and connects to a pipe that runs under the top shelf. Water flowing through this pipe under the top shelf propels the sprayer arms. If the connection at the back is not flush with the "propel" pipe there won't be enough water pressure to turn the sprayer arm. Check to see if your dishwasher has this type of set up.
I hope this works. If it does, please let Fixya know by rating my solution.
Good luck!

I have owned my LG stainless dishwasher for 3 years with no major issue. But now when the entire cycle is complete there is a white film that remains on the dishes. I have switched detergents but it...


If your dishes or glassware appear with a white film or a white powdery residue or spotted following a complete wash cycle, adjusting the amount or type of detergent you?re using and adjusting your hot water heater?s water temperature may solve the problem. But before you do either of these, put a rinse additive (such as Jet-Dry) in the rinse dispenser to improve the sheeting action of the water.

Next, you?ll have to determine whether the film is removable or permanently etched. To do this, soak a glass in undiluted white vinegar for about 15 minutes. Or, wash the glass with warm water and concentrated dishwasher detergent or a high-phosphate detergent (such as Glass Magic).

If the film comes off, it is probably caused by hard water minerals, improper amounts of detergent, or unsuitable water temperature.

Permanent etching is often caused by a combination of soft water and excessive heat or detergent. If glassware is permanently etched, there isn?t anything you can do to make it clear again. But you can avoid future etching by taking these steps:

1) Be sure hot water entering the dishwasher is no hotter than 140 degrees F. Don?t use extra-hot settings such as ?Power Scrub,? and use the ?Energy Saver? dry cycle.

2) Adjust the detergent amount.

3) Don?t pre-rinse your dishes before loading them in the dishwasher. Food particles on the dishes actually help the detergent and drying agents clean better.

A common cause of poor washing results is improper loading?dishes that block or impede the spray arm(s) or prevent the soap dispenser from opening. On the other hand, if your dishwasher has chronic problems with good washing, the problem may not be your dishwasher. A good first step is vary the amount of dishwasher detergent you're using and try switching brands.

Other possibilities: Your home?s water pressure may be too low, your water may be too hard, or the water temperature may not be hot enough.

In order for your dishwasher to fill to the appropriate level, water pressure should be from 20?120 pounds per square inch. If you suspect that your water pressure may be low, turn off all faucets or other users of water (such as washing machines and sprinklers) and then put a half-gallon jug under the kitchen faucet. Turn on the hot water full-blast. If the jug doesn?t fill within 14 seconds, your water pressure may be too low for proper dishwasher operation. Call your city water utility to discuss your options, or avoid drawing water elsewhere in the house or yard during dishwasher cycles.

The right amount of detergent to use depends on how large your load of dishes is and how hard your water is. Hardness is measured in grains of minerals?the more grains per gallon you have, the more detergent you?ll need. If your water has 12 grains or more of hardness, fill both dishwasher soap cups completely with detergent. If that doesn?t work, consider installing a water softener. (For more information, see the article Water Softener Systems.

To check water temperature, hold a meat thermometer under the hot water faucet for two minutes; if it doesn?t register a minimum of 140 degrees F., turn up the temperature dial on your hot water heater. (However, if you have a newer dishwasher that heats the water internally, it isn?t necessary to turn up your hot water heater.)

If your dishwasher has worked fine in the past but suddenly your dishes aren?t clean after the dishwasher completes all cycles, listen to the spray arm(s) spinning inside during the wash cycle. If spinning poorly, wait for the machine to cool down, remove the spray arm(s) by unscrewing the hubcap(s), lifting the arm(s) off, and then cleaning out the spray holes in the spray arm(s) with a stiff piece of wire.

The top two water water arms do not spin


These spray arm will only get water several times in the wash and rinse cycle. They do not turn at the same time the lower (bottom large spray arm under the bottom rack).
There is a chamber that diverts water either to the bottom sprayer or to the top sprayers, not to both at the same time.
If your top spray arms never get water, then there must be an issue with that chamber motor to divert the water. A new sump assembly that has all the new parts.
Good luck.

if the soap/detergent isn't completely rinsing out of dispenser, it sounds like water isn't directed the top spray-arm. possible a defective vario motor; as it directs water to the water channel that supplies water to the middle and upper spray arms.

We have a Hotpoint Dishwasher HDA3400Go2WW in our two year old home. It has been very loud from the start. We are thinking of replacing it because it is so loud. Is there anything we can do to it to make...


Dishwasher noise is such a pain, especially in a new kitchen that you need to leave just to have a conversation.

There is nothing to be done to make the dishwasher quieter. Upgrading is the way to go. I now own the amazingly quiet LG LDF8812ST which works well for me and is EnergyStar rated. I really did not know the dishwasher was running, and visitors often comment on how quiet it is as we chat around the kitchen table.

But it takes time to get used to a water and energy conserving dishwasher. You need to make sure the arms are not blocked with each load and not use ultra-cheap detergent powder. Also, the plastic items will not dry like the older dishwasher.

Good Luck!

LG LDF6920ST Bottom spray arm dose not work


The LG LDF6920 dishwasher has an innovative "Vario" motor/check valve. It switches between full power spray on the upper arms and the lower arm. So, if you are looking inside the dishwasher to see which arm is spinning, you just have not opened it when the lower arm is turning.
if the root problem is that your dishes are not getting clean with this water conserving DW, go out and buy a name brand detergent powder - like Electrosol or Cascade. And use less powder then you have been using.
Good Luck!

No water going in to dishwasher when rinsing


the pump shouldn't turn on when the rinse cycle is on - it uses only fresh water straight from the water line - after the wash cycle is over - wait 5 seconds, then open the doors and see if there is any rinse coming out of the rinse arms.
If only a little is coming out - check the rinse arm spray jets to see if there is debris caught in them -
if no water is coming out - it could be a faulty rinse solenoid
