Question about Dishwashers
My Dishwasher AEG 40740 makes some strange noise. After I close the door and dishwasher starts working everything is OK and all I can hear is water hitting the dishes. After about 20 seconds this noise starts like scratching or end of water going down the drain. This happens every 5 seconds. If I open and close the door everything is fine for 20-30 seconds and then starts again. Please help.

SOURCE: Dishwasher not spraying
It could be a motor or a pump issue. The dishwasher has a motor that attached to a pump which forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher. The motor (and pump) located beneath the dishwasher. Good luck!

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

SOURCE: water not going in
This is a little late for the OP. But, I had the same problem over Thanksgiving of 2008. I searched online and saw that other people had the same problem, but there were no solutions posted. So, I paid $130 for a service tech to come fix the problem - maybe this will save you some time and money.
The solution was simple...pour boiling water (I boiled about a half gallon of water in a cooking pot) straight into the pump where the water sprays out of. You don't have to pull your dishwasher out and no tools are needed. Just open the door, pull out the lower roller tray, remove the bottom spray fin (just pull straight up), and pour the boiling water straight into the hole where the bottom spray fin was attached to. Next, put everything back in place, push the Power switch on, select a wash mode, and close the door. The dishwasher should start spraying water inside as usual.
The service tech told me that there are only two pumps in this dishwasher...one to pump the water in (the one that had the problem) and one to pump the water out. When you don't use the dishwasher frequently, the seal in the wash pump seizes up (sticks together). You can hear the motor humming, but the pump isn't able to send the water up into the spray fins. By pouring boiling water into the pump, it helps to break that stickiness and allows the pump to start sending water up into the spray fins. The solution is to run your dishwasher at least once a week. Even if you don't have much to wash, run a rinse cycle to let all the parts move and stay loose.
One other tip the tech told me is to pour a cup of white vinegar into the pump when you go away on vacation and the dishwasher won't be used for a week or more. This should keep the seals from sticking together. I haven't tried this yet.
Hope this helps.

Hi you probably have something in the sump drain assembly (this is a common problem with Nautilus DW's) there's a screen on the right side of
the spray arm with 2 screws remove them and take screen off use your
fingers to probe the cavity be careful it could be glass.
If it does not correct the problem
!.You may have an electric pump . and it could be pump without water . so i would say a bad pump....but since you say everything is draining well...then I doubt the later...HOWEVER...you did say it ran forever...which is absolutely typical of something in the sump...drain area...which will make the drain cycle run because it believes something to be in the drain.....there is also a check valve...that the drain hose attaches to...(it comes right off of the motor assembly) when you take the hose off there is a check valve that screws into the hose or the motor assembly...(it could have debris in the hose that is not being drained all the way out and it is finding it's way back to the check valve) ...shop-vac the drain line...or the valve is screwed into the motor assembly where the hose disconnects...and there may be something stuck in the valve...unscrew it and check that the valve is in good shape...and free of debris......reassemble...and run through cycle....if you need any of these parts...or any specific instructions on replacement of these parts...here is a great site...Quality for less and quick delivery.
I hope this helps...I believe it will....Good luck and good day....thank you for your rating my effort....The Fang.
