SOURCE: dishwasher not draining and making a noise

Ok, normally, when you hear abnormal noises and the draining has stopped, this will point to the pump/motor assembly. this assembly , basically, runs together in unison. the pump/motor are as one and if the motor is malfunctioning, the pump will not drain properly. this noise is coming from the pump housing. There are many parts that are located in this housing and one fragile part that can cause issues is the Impeller. this piece provides the pump action that moves the water during drainage. If the sleeve that connects to the Impeller becomes stripped, the motor drive bolt will simple spin freely, causing this noise and no drainage. The motors fine but, you will have to replace the pump assembly in order for this noise to stop and the normal draining cycle to return. just to be safe, check all the drainage hoses as well.

please rate and god bless:)

SOURCE: Dishwasher making loud noise during wash cycle

It's noisy If your dishwasher seems noisy, check these:

Water-inlet valve
Heater fan
Water-inlet valve An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve. 

Motor If it's the motor that's noisy, either of these may be the "culprit:"

  • As motor bearings wear out, they can become quite loud when the motor runs. They wear out quickly if they frequently get wet, because the water washes away the motor bearing grease. Bearings can get wet if the spin seal is defective. Then there will also be water leaking onto the floor beneath the dishwasher. Replace the seal if it leaks (read about the main tub seal in the "It leaks" section, later).

  • If, from beneath the dishwasher, you can see a round, plastic disc that's mounted to the top of the motor (a "slinger"), it may have broken free of the motor shaft. If so, it could be rattling around the shaft while the motor is running. If that's the problem, you need to replace the motor.

Heater fan If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.

Pump Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. 

To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.
thanks and accept the solution accordingly

SOURCE: Whirlpool Gold Dishwasher makes a very loud noise when running

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 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) 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 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.

SOURCE: LG Dishwasher LDF7811 Making Growling Noise

-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?

I have a samsung dishwasher that won't drain it makes a cracklings noise then the quick light starts flashing if I unhook the drain line and hold it lower in a bucket it will drain

If it is making crackling noises, it has water on electrics and is shorting out. Unplug it a call a technician before you have a fire.

Unhooking the drain line and lowering just allows water to flow past the pump.

Hotpoint Aquarius dishwasher making awful rumble/crackle noise

Have you cleaned the traps and run some vinegar through? They build up dirt from kitchen debris over time which causes the pump and spray rails to pick up sludge. You need to clean them at least every 6 months. Check farther on line for cleaning solutions to clean and maintain dishwashers. I have been hearing clr can be used but can't confirm this.

it's probably your pump starting. has it always made this noise or just started. or does the noise start then go away? if it stays on all the time i'd say your pump is getting ready to go out this is something you could change yourself save $$$ just get the make and model # of the side of door. then call an appliance store see if they can get one first before you take it apart if it's an old model might be best to get a new one (dishwasher) if and you get a pump the water shut off should be under you sink just the hot then pop the cover off bottom of dishwasher (TURN OFF POWER FIRST TO DISHWASHER!!!) it would easier if you pulled the unit out then tilt it back and you'll see the pump the rest is pretty easy. good luck

My Kenmore dishwasher makes an intermittent crackling noise during one of the cycles!

The crackling noise is something caught in the pump housing area. This may eventually wash out but usually disassembly is reguired.

LG Dishwasher making grinding noise then blinking E1 code 10 minutes later

Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!
