Rattle Noise in motor - DU920QWD

Our 920 dishwasher is 10 years old and a rattle noise has developed in the area of the motor. Could that be a sign the motor is going or could it be some other problem. If it is the motor, how difficult is it for a handyman to replace it?

Dishwasher makes a lot of mechanical noise when running


If your dishwasher seems noisy, check these:
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.

1 Look at the heater fan to check for rusty or squeaky parts. If defective parts are found, replace the fan. If not, go on to the next step.
2 Replace the water inlet valve, which is located at the bottom of one of the sides of the dishwasher, beneath the lower access panel. As a water inlet valve ages, it can sometimes slowly stop working correctly, switching between "on" and "off" every few seconds. This can cause a shaking and rattling noise. If this does not fix the noise, go on to the next step.
3 Remove the lower rack and the lower spray arm from the dishwasher, removing any screws as needed to do so.
4 Beneath the lower spray arm is a pump that contains a propeller. Check the pump for debris (like small bones, seeds, or fragments of glass) that might be causing the noise. If this does not fix the noise, go on to the next step.
5 Beneath the pump is the dishwasher's motor. Check to see if the plastic dish at the top of the motor has broken off. If it has, it may be rattling when the motor is on and causing the noise. In this case, replace the entire motor.
6 Check the bearings on the motor. If they are worn out, replace them.
7 If you cannot trace the noise to its source, try replacing the motor.

When washer is started make loud grinding noise


Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

Reply back and we can you more.

Water is not draining. I can hear a rattle when it


the best way is to try and picking it with some wire, or if it's metal, use some magnet on a string and try to pull out the cloge, if nothing of that sort doesnt work, you will need to pull washer out and disasembel it

Not washing


Hi, there is a circulation motor that has an impeller attached to it. this is called the wash motor. it is located under the sump area. this wash impeller has become damaged and, you will need to replace it asap. this is causing the grinding noise. the impeller may be stripped or, it has slipped off the shaft. replacing this damaged impeller will fix this issue.

Rattling noise in my kenmore dishwasher


This is probably due to a defective motor. The fan blade will actually become disconnected from the motor armature and will rattle around on the shaft.

It is easiest to replace the whole motor and pump assembly as a unit. They cost about $100.00 or maybe a little more.

It is not hard to replace if you have your machine pulled out from the wall and upside down or on its side.

It is only a few screws and plugs.

The diswhasher is noise


need to know what kind of noise. could be something caught in the pump. when does the noise occur relative to the full cycle. is it a rattle that happens once in a while, or constant when the pump is running.
while thinking about this, check the drain filter in the bottom and make sure there is nothing visible there.
let me know
