Don't know what you call it but the arm that sprays water underneath the upper rack of dishes is clogged 'cause I can see stuff coming from the holes. Its a Maytag quiet series 300 but I can't figure out how to get it off. Past dishwashers had a screw that I took off. Help! I know it could be an easy fix

Re: Upper rack spray is clogged
It has a pressure insertion fitting that snaps into the arm thru the hole,you need to press in on the ears on the bottom of the are to release the plastic grips to let it drop out,then the arm should remove after this

There should be an upper spray arm to wash the upper rack, it may be stuck. Look at its position, run the machine a few seconds and see if it moved. The spray nozzles on the arm often get clogged with food particles. the pipe feeding the spray arm has to extend when you pull the rack out and retracts when you push it in. Make sure it works properly and has not disconnected.
Most dishwashers have a rotating spray bar underneath the upper rack. Over time bits of food can clog up the holes and then dishes won't get clean in the upper rack. Check to make sure all the holes in the spray bar are clear and that it is rotating freely.
A couple of scenarios could cause this problem but the simplest might be the way the dishwasher is loaded. The upper spray arm rotates when water is pumped through the vertical supply tube and into the arm. Make sure that you are not loading the lower rack with items that interfere with the rotation of the upper arm rotor. It might also be a good idea to verify that the feed tube that goes to the spray arm is securely connected to the vertical supply tube.
Check your upper wash arm.... check the holes, especially the ones at the end of the arm. Are they possibly clogged with debris or hard water? This is the usual cause of dishes on the top rack not getting clean. The holes at the end of the wash arm are angled to eject the water at an angle to use the reaction to push the wash arm around. If those holes are clogged, then the arm won't rotate, and only those few dishes or glasses right under the arm will get clean, and the remaining 80% of the dishes on the upper rack won't get clean!
Possible causes of spray arm inefficiency: Loading large or tall items in the lower basket which stops the arm revolving. Upper spray arm split along seam. Upper spray arm blocked. Under dosing of powder causing foam and reducing upper spray arm water pressure. Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure. inefficient wash motor impellor (faulty)
maybe not... if unit is incorporating more than one spray arm,chances are the upper spray arm is not getting water.pull top rack forward,gaze under top rack near rear manifold.slowly push rack back in.notice if manifold inserts into upper wash feed.if so,possible motor issue. if not,bingo was his name-o!
Make sure you get water to the dishwasher. Check to see if the water
shut-off valve (located under the sink) is open. If you get water to
the dishwasher, but there is still no water inside during the fill
cycle, the problem might be with a faulty water valve (located at
the bottom of the dishwasher, behind the kick panel, on either
side), in which case replace the water valve.
If there is not enough water, the dishes would not get cleaned. This
could be caused by a partially closed water shut-off valve (located
under the sink), or a faulty dishwasher water valve (located at the
bottom of the dishwasher, behind the kick panel, on either side).
There is usually two, sometimes three spray arms in a dishwasher.
Make sure there is no debris blocking the holes inside each spray
There is a screen that you can remove from the sump of the dishwasher to clean. Just twist it to the left and pull it out. I have some tips that you might want to check out if this does not resolve your problem. <a href="http://tclaundryrepair.com/">St Paul Appliance Repair</a>
only the top rack isnt getting clean? there is a little plastic
circle in the middle of the bottom of the upper spray arm. turn it
counter clock wise to pull the upper spray arm from the upper rack.
make sure that isnt clogged and the spray holes are not clogged.
the piece that the bottem spray arm plugs into and
runs along the back wall of the tank to the top is called a feed tube.
pull the bottom spray arm out. now you can see the part of the feed
tube that feeds the upper spray arm water. does it pop out freely and
easily? if so then you need a new feed tube, if not then its most
likely your not achieving the right water level or your impeller
connected to your circulation pump(motor) is clogged not supplying
enough water pressure to travel up the feed tube to spin the upper
