Question about Whirlpool GU2400XTP Built-in Dishwasher
The dishwasher functions normally except for the following problem. When it is washing it makes a loud humming/whining noise. The washing cycle periodically pauses and the noise disappears but starts again when the dishwasher resumes washing. I checked the chopper assembly and removed any debris from this area and the sound remains. I also ran throught the diagnostic cycle and the noise is only evident when the wash motor is running. If the problem is in the pump motor or pump sump is there a good way to find out which it is? Any help is appreciated.
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:"
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.

When the dishwasher first comes on there is an intermittant rubbing sound. Any ideas?
