-Switch to a brand name detergent powder - like Electrosol or Cascade and do not fill the dispenser cup full. You will notice the difference immediately.
-Remove the filter assembly one more time and inspect underneath with a flashlight. Look closely for debris and also inspect the impeller to look for damage and that it is spinning freely.
Reassemble and listen for the growling sound. It should not happen. If it continues, you may have a a failing wash motor / motor bearing.
Please report back what you find. OK?

Hey, consider the float assembly!
We bought this dishwasher and ran it for the last 1 1/2 months and it made a grinding and whistling sound from day one (it's supposed to be nearly silent in its operation). Turns out the drain pump was cutting in while the machine was still filling, thereby emptying the wash tub of any water. Then, when the cycle proceeded to wash, the dumb thing had no water and made a horrible noise. So I had to pitch in at least 2-3 litres of hot water, and then it worked quietly! Had to do this every time there was new water intake.
After working with the repairmen - four visits later, we isolated the float assembly as the problem and they set about replacing the part. Turns out the two parts were markedly different. LG HAD INSTALLED an older model float assembly at the factory and it was the problem. The replacement part was the correct float assembly and things worked perfectly after that - thank goodness. No more babysitting the dishwasher.
Don't let anyone tell you the motor assembly needs replacement. I have seen that cop-out 'fix' all over the web. But use deductive reasoning to find out where the problem is in the cycle, and explore this option first - it's a quicker and cheaper fix than replacing the whole motor assembly.
'Mr. Float' as he is now called works like this:
-expels any residual water in the tub from the last wash
-intakes water for the wash or rinse
-whirs 2-3 times prepping for the cycle
-begins to wash, quietly
-expels at the end of the wash or rinse.
He used to:
-expel residual water
-intake new water for wash or rinse
---drain pump would cut in WHILE still filling
-machine would whir once, realize it didn't have enough water
-perform a brief top-up intake shot
-begin to wash and whistle and GRIND (this is where I would have to add the water)
-expels water from wash or rinse, and start all over again.
It's a good dishwasher and it will work, but the right model parts have to be in place!
