Question about Dishwashers
SOURCE: Loud vibrating/humming noise
Okay...based on the model number, this is a Frigidaire manufactured dishwasher. If you go to searspartsdirect.com and type in the your model number in the Search menu, you will find a useful illustration under the "Motor and Pump" heading. The drain pump is listed as item #60 in the drawing. Before you go through any major dis-assembly, check to make sure the pump is securely in place and not loose. Sometimes the pump comes loose from the mounting bracket and vibrates. Also, sure nothing is laying against it causing vibration noises (I've seen this before). If the solution is not that simple, remove the spray arm assembly inside the dishwasher and inspect all the debris traps under the spray arm assembly. The wash pump and drain pump sumps are located here. Check to make sure there's nothing obstructing the input to the drain pump. Lastly, if all else fails, remove the drain pump and inspect the impeller. If the you've inspected everything and still have the noise problem, replace the drain pump. The motor could possible be failing. The part number on the Sears website is 154580301 and costs about $40. Repairclinic.com has the same part listed as item #1257094 for $37.50 if you wish to do some comparable pricing.
I hope this helps you. If you need further assistance, please post back and let me know.
PS Even the quietest of all dishwashers will make some noise. However, if it has gotten to the point where you can hear it in the next room, you probably need to inspect to find the source of the problem. This is not true with all dishwasher manufacturers, but in many cases, the only difference between your "Quiet-Pack" line and regular low-end models is added insulation behind the door and lower panel to help quieten noise.

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..

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.

I have the same problem with my dishwasher. If you remove the kick plate while it is running, There is an electric motor underneath. If you push up and pull forward on the electric motor, the noise will stop. I used a block to prop it up and the noise stopped. You may want to try it.
