Hi,

It could be the motor bearings, they can go out if the pump seal starts to leak and moisture gets to the motor bearings. If that is the case you are looking at about $180.00 for the sump and motor (parts only).

It could also be something caught in the sump near the chopper that is creating the noise. Here is a link to some clean out instructions if you are up for trying them.

SOURCE: Kitchenaid Dishwasher has starting making a real loud noise

Hi Andy and welcome to FixYa. I am Kelly. That loud noise your hearing is the motor bearings. If you were to remove the lower kick panel you will prbably find signs of a slow leak of water has been trickling through the motor and you will see a water spot under the motor pump assembly.
You were correct in your assumption that it was bearings. What happens is the motor shaft ceramic seal starts leaking long before the home owner even notices it. Then the water gets into the motor and corrosion starts to build up. As the motor turns the bearing starts to spal as a result of the corrosion and you hear the loud noises.
The only fix for this sadly to say is a complete motor impeller assembly replacement. If your model number is the one associated with this post / question: KUDI01FLSS then there is one more digit after the last "S" that being one of the following numbers 0, 1, 2, 3, 4, 5 or 6.

The motor and impeller for your dishwasher Item 10 or 18 can be found here and is listed at $138.44:

The seal that has failed is item 23 of the same link. Changing the seal at this point will not stop the noise.

Thanks for using FixYa.

Why is my whirlpool dishwasher making a loud noise during drain, wash and rinse cycles?


They can be complicated to re-assemble. Best solution is to video the procedure (if you have a video camera) during disassembly and make notes and diagrams to orient things properly and make sure the correct screws go back where they shoud. Takes more time, but you'll be glad you did, it will save you a lot of aggrevation in the long run.

Dishwasher is making a loud noise


Sounds like there is something in the filter trap that is right before the mini disposal that is a fan blade, on top of the motor.

There is a loud noise while going through final stages of wash. Sounds like pump motor whineing.


Hello

When an appliance such as a dishwasher starts making a new noise, you need to isolate the cause of the noise so that you know whether or not it is damaging the machine. Several things can cause a noisy dishwasher.

Motor

Dishwashers are driven by an internal motor that gets quite noisy when defective. The problem occurs when a seal breaks down and allows water to access the bearings in the motor, removing the grease needed for proper lubrication and creating a loud motor noise when the dishwasher runs. The seal or bearings need to be replaced in this situation quickly or more extensive damage to the motor may occur.

Inlet Valve

If the inlet valve on your dishwasher is broken or breaking, you will hear a distinctive thumping or clattering noise whenever a load is run. A thumping noise doesn't always indicate this problem, however, depending on when you hear it. If you hear a noise like this when the water is filling up the dishwasher at the start of the cycle, the noise likely points to an inlet valve problem.

Squealing

A high-pitched squealing noise is an indication that something is wrong with the fan. Fan bearings that are worn out indicate that the fan apparatus needs to be replaced. If the noise you're hearing is in fact coming from the fan, it will only occur when the dishwasher is drying the dishes. Dishwashers use a fan to generate and distribute heat to dry the dishes quickly.

Minor Concerns

Sometimes even a minor concern can cause a great deal of noise. The thing to watch for is whether or not the noise repeats itself on multiple loads. A loud noise on a single load that doesn't repeat could be caused by things like a loose utensil or small implement rattling around loose in the dishwasher. Also inspect the bottom of your dishwasher. Hardened bits of old food can become rock hard under the heat in the dishwasher and cause noise when the unit runs.

Fridgeair dishwasher not working making loud sound. water comes in and I can make it drain out but washer does not start


Hello

bearings in the heater fan may get worn out or rust. If this happens, it may become very noisy, either grinding on the bearings, or scraping against the rust. If this happens you need to replace the fan motor. Sometimes, a fan blade may come loose, and you need to replace it.
Sometimes it's the motor that makes the noise you hear. The motor has bearings in it which may become worn or get rusty. When the bearings get worn, they allow the shaft to wobble which can get quite loud. If there is a spin seal leak, water may get inside the motor, washing the bearing grease away. If the spin seal is leaking, you'll notice water leaking from under the dishwasher. There is also a disc attached to the top of the motor called a slinger. It sometimes breaks off and spins around the motor's shaft while it turns, causing some noises. You will need to replace the motor if the bearings are bad. You also need to replace the motor if the slinger is broken as well.

Newer dishwashers may make a squealing or rattling noise on the first run. This is because it has not had any water in it yet, and the motor seals are dry. You may hear this in a unit that hasn't been run in a week or more as well. You should operate the dishwasher regularly to keep the sump water from getting smelly, and to keep the seals lubricated. You can add a quart of water to the sump before running it.

Rattling noises may be produced by dishes rattling inside the dishwasher due to the water pressure from the sprayer arms on the dishes. To determine if the rattling is a loading issue, run the unit empty. If the sound is persistent, it may be that there is debris in the pump.

dishwasher water-inlet valves are noted to make a hum that lasts about 60-90 seconds several times during a washing cycle. This hum is a different hum than the sound of the motor running.

A rhythmic knocking or thumping sound may be caused the sprayer arms hitting something as they go around and around. Rearrange the dishes and resume the wash.

A clunking or clanking may be heard when the detergent cup opens; while a clicking sound may be produced by the timer or electronic control panel.

A solenoid makes a snap sound when it opens. This happens about six times during each load.

Pipes rattling or banging may be caused by a water hammer effect. Water hammer sounds are caused by a valve closing in the system, and yet the water in the pipe is still flowing because of its kinetic energy. The sound is caused by the water slamming into the closed section of pipe. A plumber can install an anti-hammer device.

Small objects can sometimes get stuck in the pump. When this occurs, you'll need to open the pump and then remove the item that is making the noise or replace the pump. The dishwasher pump is usually mounted directly to the motor and runs off the motor as well. The pump is also attached to the bottom of your dishwasher.
