you should not have to use any type of screwdriver to remove filter. The rest of it , leave alone. Take both rotors out and run unit. Both rotors top and bottom should push water through at a good rate. If not, a blockage in water /motor line. I suspect the rotors simply need to be properly cleaned, If not rotating properly it will cause undesolved residue.

The problem is hard water. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to www.dishwasherfilter.com to find out more info.

thats easy you can go sears parts direct and give them the model # they will give you image and the part# and also you can order it direct and have it sent directly to you. let me know if this info is correct with a 4 thumbs

it may not be the spring it could be the cord it connects to you can check this by removing left or right hand side panels which will expose the hinge.good luck

Are you having any issues with your water heater at all. Make sure to run the water at the kitchen sink on the hot side first ti ensure hot water is getting to your dishwasher. Also make sure that the jet dry dispenser has jet dry in it. Hope this helps.

If your dishwasher is cleaning poorly, check these:

Water-inlet valve
Internal filters
Drain valve
Spray arms
Water temperature
Detergent cup
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.

Dishwasher Water Inlet Valve Replacement

Be sure to read and understand any instructions that come with the new water inlet valve.

Tools required:

Adjustable wrench

Multi-Screwdriver

Pliers

Step 1. Disconnect the dishwasher from its power source.

Note: Dishwashers are usually wired directly to the home’s electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.

CAUTION: If you’re not sure you’ve shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair.

Step 2. Turn off the water supply to the dishwasher. This is usually underneath the kitchen sink or in the basement or crawlspace near the location of the dishwasher. Pliers may be helpful here.

Note: If there are no shut-off valves, you must shut the water off at the main water supply valve for your home.

Step 3. Remove the lower panel(s) of the dishwasher. These are usually held by 2 to 4 screws at the upper and lower corners of the panel(s).

The inlet valve is usually near the front of the dishwasher. Attached to the valve you’ll see: 2 or 4 wires, the water supply line from the house and the water feed line that goes to the dishwasher.

Step 4. Remove the household water supply line from the valve. The line is usually secured with a brass compression nut. The water supply line is usually copper or braided stainless steel.

CAUTION: Water supply line may be hot.

Step 5. Remove the fitting from the valve the water supply line was attached to. This fitting may be very difficult to remove. It may help to put the valve into a vice in order to remove the fitting. If you cannot remove it, replace it. The fitting is not an appliance part but a plumbing part that is available at most hardware stores.

Step 6. Remove the screws holding the valve to the dishwasher frame.

Step 7. Label the wires to the valve so you’ll be sure to reattach them correctly.

Step 8. Remove the wires from the valve.

Step 9. Remove the clamp on the black rubber water discharge tube and pull the tube off of the valve.

Step 10. Reinstall the old fitting (or a replacement fitting if necessary) onto the new valve the water supply line was attached to. Use Teflon tape or pipe joint compound as a thread sealant. Make this fitting tight to prevent leaks. Make sure that the fitting points in the same direction as the old one so that the water supply line will meet up with it properly.

Step 11. Install the new valve in the reverse order of the removal instructions.

Note: The water supply line is under high pressure. Be sure to tighten the fittings properly.

Step 12. Turn on the water to the machine, and check for and correct any leaks.

Step 13. Reinstall the access panel(s). Restore the power to the dishwasher and test.

Note: You may have to let the dishwasher run a few minutes before it reaches the next water fill cycle.

Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:

• Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.



• Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.

If your filter is clogged, it may be causing the cleaning problem.

Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.

Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.

If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary.

Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps.

To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

Hi, there may be an obstruction in the pump housing that is causing the motor to freeze or, the impeller may be stripped and , jamming the pump. this will cause the hum you are hearing. the best way to inspect is to , extract the drain pump by, removing
the bottom drain filter housing or sump. manually
move the pump impeller to self it is moving freely. if the impeller is stripped, it will not be able to produce the draining surge necessary to pull the water out.

If the impeller is fine and, there are no obstructions visible, this will confirm pump failure.. replace the pump in this case


Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

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.

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?

Hi there,
The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor. 
else you need to REPLACE THE PCB POWER CONTROL BOARD

I actually own an LG LDF8812 myself, except mine is stainless steel, not white. So be it. :-)
Anyway, it sounds like you have just unboxed the unit and it is brand new, not just new to you. I am also assuming that you have this dishwasher connected to an Air Gap valve which is connected to the garbage disposal. Please reply if I am wrong.
Because it is (apparently) new, the first thing I would check is that any water is draining from the unit. A common problem on new installations is that the knockout inside the neck of the garbage disposal unit. A quick way to test that is begin the dishwasher filling, then open the door and press the two buttons that give you Cancel. Hold for three seconds and the DW will begin to drain. Being careful of the hot water that should be draining into the kitchen sink via the disposal, but watch for water to come flowing with a healthy stream - not wimpy.
Please reply with what you have found and correct my assumptions that I got wrong. Good Luck!
OH, if the problem is not something at the end of the drain hose, before you try to crack the unit open (and possibly void your waranty) dial the number on in the user guide and schedule a service call asap. Have your proof of purchase available.

some have little tabs to push to unlock the filter. what is your model number?

It is important to know that the upscale LG diswashers alternate between washing the top and bottom rack. So it is normal for some arm to not be turning at certain times.
Also, if this dishwasher is set to half load, bottom only, the top arm will never turn.

IE is inlet error, displayed when "Not reached to the normal water level in spite of 10 min. water supply"

Possible cause:

• The Water Supply Tap is closed.
• The Water Supply is shut off.
• The Inlet Hose is kinked.
• The Water Pressure is very low.(below 10 psi)
• Inlet Valve is OK?
• The filter of Inlet Valve is clogged by impure water.
• The Hall sensor is OK?
• The Impeller of Air Guide is bound.

Remedy:

• Cut power by tripping circuit breaker or unplugging power cable for ten minutes.
  
• Take action on Water Supply device.
• Measure the electric resistance of Inlet Valve. (950-1300 )
• Clean the filter of Inlet Valve.
• Check the frequency of Inlet Water by the Test Mode.
• Replace the Air Braker.

you need to clean the stainless steel with good tetergent and hot water to clean the steel
ss wipes do not do much good and only put a film of oil on the surface
once you clean surface with soap and water use a stainless cleaning cloth you can buy from cleaning store
use the with just water and wipe dry
keep the cloth in a plastic bag to keep from drying out

This sounds like you have a problem with the thermostat.
Repair would be cheap. Are you mechanically inclined?

see if your drain is plugged or anything

I do believe so.  Check your installation guide for more info.  If you purchased a water line designed for dishwashers, it should have the 90º elbow included.
