I have a Kenmore dishwasher Model # 665.1376 which has always been a quiet unit. This dishwasher is about 4 years old. Now the dishes still come clean, however the cycles have a loud hum to each except for the dry cycle. Could this be a bearing in the motor, and if so how expensive is a new motor?

SOURCE: Where is the filter on a Kenmore Quiet Guard 2 dishwasher?

I have a Quiet Guard 4. Same problem so will describe my solution.
1. Remove bottom basket. Remove top basket.
2. Remove bottom washing arm. Unscrew (Gently but firmly) the centre post. Lift arm assembly up and out.
3. Remove overhead conduit. One screw at back, one at top (Philips #2 bit). Rotate whole assembly 45 deg right (Clockwise) and lift off of centre post.
4. Remove centre post (Pull straight up). Remove 4 screws (Star T-20 bit). Lift whole assembly out. Pop off screen and clean.
5. Remove cap over cutter/chopper. There is a single screw at front left (under assembly removed in 4). Remove screw (Star T-15 bit) and cap (Needs some wiggling to free it up). Remove cutter and filter. It is on a spring loaded pin. Pull the cutter blade foreward and then the filter disc straight up. Clean thoroughly as it may be the cause of your problems.
Reassimble. Good luck!

Very common problem is soap build up in these machines. Try putting it into a wash cycle with no dishes, and no soap. Let it wash for about 5 minutes, and then open the door. If you see alot of soap suds, then soap build up is the problem. Try doing a couple loads with no soap, and no dishes, and throw a cup of vinegar into the machine halfway through the wash. Repeat as necessary. This should solve your problem.

SOURCE: Dishwasher making loud noise during wash cycle

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

Water-inlet valve
Motor
Heater fan
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.
