Yes. The water pressure in the hydraulic system is very important.
If more water flows through the hydraulic circuit of the lower nozzle, then probably that the upper nozzle will not rotate which will cause poor wash results.

If is clean dishes in the upper basket, I conclude that the pump produces enough pressure what means that the lower spray arm for some reason does not rotate and because that washing result is bad. Before washing I would check the lower spray arm rotates freely and after that open the door during washing and check if the lower spray arm rotates. Sometimes, the holes in the spray arm clog and disable turning which leads to poor washing results in the lower basket.

follow this steps and fix it. God bless you

Water Inlet Valve

If the dishwasher is leaking water the water inlet valve might be defective. If the water inlet valve sticks open, it will allow water to fill the dishwasher continuously. Some customers report that they see clean water filling the bottom of the dishwasher after it's been sitting all night or for a couple of days. If this happens, turn off the water that is supplying the dishwasher. This is normally a valve under the kitchen sink. Then, replace the water inlet valve, it cannot be repaired. The water valve needs at least 20 lbs pressure to shut off properly. If your water pressure is to low replacing the valve may not solve the problem.

Center Wash Arm Assembly

If the dishwasher is leaking water, the center wash arm assembly might be cracked or split. This can allow a jet of water to spray toward the door seal, causing a leak. If a crack or split in the center wash arm assembly is found, replace it. There isn't any glue that will hold the part together inside the dishwasher.

Lower Wash Arm Assembly

If the dishwasher is leaking water the lower wash arm assembly might be defective. If the lower wash arm has a crack or split on the end, it can force water to spray directly toward the lower part of the dishwasher door. Then, the water can be forced under the door and onto the floor. Check the lower wash arm for any cracks or splits and replace it if necessary. Also make sure the screws are tight in the wash arm support. If the screws are loose, water can spray out the side of the pump and cause a leak.

Upper Wash Arm Assembly

If the upper wash arm assembly is broken or cracked it can cause water to spray very forcefully toward the seams of the door, causing a leak.

Door Seal

Every dishwasher door has a door seal. If the dishwasher is leaking water, it might be that the door seal is defective or worn out. Try closing the dishwasher door on a dollar bill and see if the door seal is making good contact all the way around the door. If not, replace the door seal. If the door seal is good or has been replaced and there is still a leak check the door hinges. If the hinges are bent the door will not close properly and the hinges will need to be replaced.

Hi Matt.
The lower housing underneath the lower wash arm may still have something blocking the water passages.

If the spray arm is clean and it freely rotates try lightly pressing down on the wash arm and then rotate it. Your checking to see that when water is applied to the spray arm it forces the arm down against the lower housing tower and hopefully does not lock up. If it does lock up while pressing down and rotating obviously you need to find out what the cause is.

You may have to remove the lower wash arm housing and clear the debris from the water passages. Once the passages are clear it should work fine.

Thanks for using FixYa,

Probably blocked spray arms is the cause of the unit not cleaning properly or rotating. Remove each spray arm (there are 3 in total) and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results.

good day,
hope this link below will solve your problem.

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!

1. make sure dishwasher is level front to back and side to side.
2. check the main washer arm (WD22X154) on the bottom side for leaks. If you use heated dry, the heating elements can cause the part of the spray arm directly over it to soften and eventually leak. When water comes out that leak it can spray at the bottom of the door, splashing water inside it and resulting in your leak.
3. if 1 and 2 OK, watch how you load the lower rack. If dishes or a bowl direct water from the lower wash arm to spray against the bottom of the door, especially at the center of the door bottom, the resulting splash inside the door allows water to hit the outer door panel and drip out a one or both corners of the door.
