FYI... I followed Miss Midget's steps... and there it was... a piece of plastic... actually one of the end caps from the rack. Poor design if you ask me. So for all you "grinders" out there, it's an easy fix... just need the appropriate star screwdriver. It went back together easier than it did taking it apart. Thanks.

I have had a Maytag Quite Series 300 for some years now and have done basttle with it on may occasions. I now consider myself somewhat of a veteran, although by no means a repair expert!
Grinding Noise: From either a clogged/blocked impeller or not enough water getting to the impeller.
For a clogged impeller, it is fairly easy to disassemble the washer to get at the impeller to remove any debris or blockages.
For not enough water it can be a number of things. First of all, you will notice that the noise lessens if you add a jug or two of extra water. This is because if the water level is too low, the pump impeller will get some air mixed with the water & this is LOUD! Now for the causes:
Float – If the float gets stuck in the wrong position (debris or water deposits), it will not fill enough.
Float Set Wrong – Seems thats some of these dishwashers have the float set a little too low to let the dishwasher perform without grinding. A few pennies attached to the float with a rubber band seems to help here. Don't go too far or you'll flood your kitchen!
Timer – Some folks have mentioned that dishwashers that fill on a timer will not fill enough in the allotted time, if the water pressure is low. While this is true, I have looked over the electrical & parts diagrams for the QS300 and I do not see a timer listed anywhere. Also, the wiring diagram appears to show that this dishwasher only uses the float to achieve the correct water volume. I could be mistaken here.
Note that in VERY hard water areas (like mine – TDS of 850 hardness or 49 Grains), the plastic fins on the cover of the impeller get very choked up with water salts and this can impede flow, leading to a low-water symptom, when in fact, there is plenty of water.
Dishes Not Cleaning:
Poor Water Flow – See above, all the above items will negatively impact dish cleaning.
Poor Q uality Detergent – After trying them all – Yes, all – Do not use cheap detergent. Buy the brand names: Cascade or Electrasol work well. I have found that by far, the little packs work the best. We found that the liquid works second best and the dry stuff really isn't up to the task at all, no matter which brand.
Spray Wands Catching – We found that our lower spray wand was catching on the bottom of lower dish tray, so I very slightly bent down the legs that the wheels mount to in order to lift the dish tray/basket a little and give the wand a little more room. This worked well.
Spray Wand Nut Too Tight – The factory seems to send the dishwasher out with the nut on the bottom spray wand tightened a little too far. Loosening this a little bit lets the bottom wand rotate much more easily.
Top Spray Wand Not Meeting Receptacle – The top spray wand is attached to a pipe that mates with a port (well, one of two ports, depending on if you have the top rack in the “Upper or “Lower” position). The pipe seems to have a tendency of missing the port. A well placed elastic band will help here. Note that on our dishwasher, by the time the first elastic band wore out, the pipe had been permanently moved to the correct position by the gentle pressure.
Tines/Dish Holders On Top Rack Falling Over – The tines (metal spikes) that hold dishes on the top rack fold down by design. Issue here is that they do it sometimes during the wash, causing the dishes to fall over and block the spray. A few well placed rubber bands help here as well.
Water Salt Buildup – If you live in a very hard water area, you can still get clean dishes from yor dishwasher. We do and we have VERY hard water. Buy a gallon of vinegar once a month. Pour this into a clean dishwasher. Turn it on so that it runs for 2 minutes to circulate the vinegar. Open the door & let stand over night. Close door & finish cycle. This will cut down significantly on the hard water salt buildup in the washer.
It's A Maytag – Sorry folks, it's true. I have learned (after purchasing the dishwasher) that Maytag has run into financial difficulty in recent years and has reduced build quality to save money. If you got suckered into buying one of these, you will very likely never buy one again. My opinion is “Do not by Maytag.”
Hope this helps someone!

Many times a complaint of noises ( grinding or scraping ) can be traced to a cracked impeller in many of the common motor and pump assemblies used today. Sometimes a poor washing complaint is common after this wash impeller has cracked. Remove power first before investigating.
The motor shaft has started to rust and swells out and this swelling cracks the upper impeller. Most times a new seal and impeller kit can cure this complaint but sanding and cleaning of motor shaft is required before replacing the new seals and impellers.
Please do rate the solution as FixYa and revert for further assistance.

Possible that the pump is not working well to spray and inject with good pressure so that the dishes are spot clean.
You will need to simulate the washer without any dish and checck the performance to understand the fault areas.
The middle section also must spray well another reason your dishes are not clean when kept low.
The entire system has to be taken out and the water flow sections must be cleaned. the pump must work and spray with high pressure or else it must be clogged , the reason for sluggish spray.
So check the inlets, the water lines and the pump.
The rest sems fine.
