Kitchen Aid undercounter dishwasher model KUDS01FL loud humming noise during wash cycle and it takes a long time to go through its cycle

    You must have the same problem as me; namely, the unit is just past warranty and it broke. It's amazing how the manufacturer can time that just right! My same dishwasher started getting noticeably louder, then it started to have somewhat of a burning odor. Today it seems to have ceased working altogether!

SOURCE: Diswasher motor making noise during wash cycle

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.

It seems that your motor on the dishwasher is going out, like mine has just done. My explanation is that it sounds like something is grinding on glass or as if a bunch of mice are making noise. Eventually, the motor will not run any more. What will happen is that the dishwasher will fill up, then make a loud humming noise, while the heating element is making the water near the heating element sizzle. Now what you have is a possible fire hazard which compounds the problem with the dishwasher. Get rid of it, take the loss and live like my grandmother used to, without having a dishwasher. That is the best advice I can give you.

If your dishwasher seems noisy, check these:
1. Water-inlet valve
2. Motor
3 Heater fan
4. Pump

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.
good luck

SOURCE: Maytag dishwasher.Loud humming noise, wash cyle,at beginning

Is the water filling up and then draining out? Mine did this and a part was broken inside the unit. The part was five dollars and called a lifter. I fixed it myself.

SOURCE: very noisy wash cycle

most times i have found a foriegn object in the pump. sometimes the machine will clear it itself but other times you have to take the pump apart. it is not too difficult but you will need a size T15 and T20 Torx aka (star) bit to get it apart. Just keep taking out screws until the filter flowplate lifts off.

Dishwasher hums intermitantly and after the wash cycle is completed


Sounds like you have a bearing going out. It could be in the system pump or the rotating washing arms. I would suggest getting ahold of Kitchenaid's customer support and relay when during which cycle the noise occurs and they should be able to identify whats going wrong.

I have a year old kitchen aid dishwasher and during fill cycle it makes a thumping noise. The dishwasher every 5 or 10 seconds shuts off fill cycle then turns back on which I think is what's causing...


Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Kitchen Aid Imperial 21 has loud motor noise duing wash cycle


loud motor noises during the wash cycle usually come from a water pump. Either the water pump will stop working soon, or it will keep working for a while longer, and the unit will stop cleaning. Sometimes the pump will stop making the noise for a while before it stops.

Loud humming just started during wash cycle


Humming can be simply due to a mechanical vibration when the wash pump is running. Alternatively it could be the sound of the detergent door solenoid which might be stuck.
Will need make and model number of dishwasher to give further advise. Does the dishwasher complete the cycle and drain out the water?

Loud humming noise when dishwasher is filling up with water


your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.

there are two components that start before the circulation pump.(wash noise you hear)

first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.

the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..
