Dishwasher fills, when the pump is supposed to start it just whir
When the wash cycle starts after the water fills the bottom, the pump sounds like its on, but no water comes out of the jets. The dishwasher
thinks it is going through all of its cycles successfully, but if the pump
isn't pumping, the dishes never get clean. Could this be a bad pump?

Re: Dishwasher fills, when the pump is supposed to start...
Hello, sounds like a broken wash impeller or a stripped drive impeller (the piece that fits inside the impeller). These two parts are driven by the wash motor and propell the water through the spray arms. good luck

sounds like your main circulation pump is not working, if it is humming when it is supposed to start, sounds like it is getiing power, so probably not the control circuits, can you measure voltage to pump? if you are getting 120 there, probably pump motor is dead
Hello, is there water in the bottom of your dishwasher? If there is water in bottom. Then try running the dishwasher throught another washing cycle. Now, if there is not water in the bottom of your dishwasher. Then the dishwasher has finished its washing cycle, rinsing the cleaned dishes. GB...stewbison
with LG dishwashers: after starting, 1st, DW pumps out any remaining water, 2nd, DW fill fresh water, 3rd, main wash motor starts, which is normally a whirring sound. (If you here grinding or rattling, then you have a problem.)
It is unclear from your description if the wash pump starts and pushes the water around but never stops cycle or the dishwasher stops as soon as the water is filled.
If you do not hear the wash pump start then it is possible the wash motor is faulty. But if the wash pump starts and never completes the wash cycle then it is possible the heater is faulty and dishwasher is waiting for water to heat up before it can go to next cycle.
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!
Hi, After the first cycle, and after it drains/spins, does it start agitating when the next load of water is suppose to be filling?
Please let me know so I can assist you further. Sounds like the pressure hoe from the tub to the water level switch is plugged.
Air gap is clean Garbage disposal is clean Dishwasher fills with water OK Drain pump runs after a wait of several minutes and seems to run slow but drains most of the water out of the reservoir. Dishwasher is not running the wash cycle (spraying water on dishes)
