I had a problem where my Maytag MDB6650 would not drain. After taking apart the sparay arm and looking into the problem I found the drain line was cloged. after re-assembling the lower spray arm it doesn't spin when the dishwasher runs.
I can spin it manually, but when running it remains idle. Could I have put it together wrong? Water shoots out of the openings and the dishwasher does drain now. Any help would be greatly appreciated.

Re: Lower spray arm won't spin
Sounds like you may have put it together wrong. I would just take the arm back off and make sure that it all fits together right. A little tip for you too. Dishwashers will clog up all the time with water deposits and food gunk. There are all those expensive cleaners out on the market but the best and cheapest way to clean them is with white vinegar. Simply pour it into the dishwasher when it is empty and run it on the pots and pans setting on hot. Always make sure to pre heat your water too by running the sink till it starts steaming. This will make it easier for your dishwasher to heat the water. If you don't, then when you turn on the dishwasher it starts to fill with cold water and has to heat it on its own. Run the vinegar though through it at least once a month or so and it will extend the life of the dishwasher. Hope this helps. Just try taking that arm back off though and putting it back together making sure everything is fitting properly. If you have any other questions feel free to ask me. Good luck.

I'm now soaked, but I was able to determine that the lower arm isn't turning. There's a LOT of water coming out, but it doesn't move. Turning by hand I can turn it freely, it spins like a top. ....

Have you tried tighten the spray arms? They may have come lose at the fittings so need to be tightened up. You can normally tighten them with your hand. Take any traps/filters out of the dishwasher and clean them. You may find answers here: https://www.maytag.com
Hi, if the water doesn't drain from your dishwasher, check the drain line and pump..
clog in the drain line or air gap (if there is one) is the usual reason
that a dishwasher won't drain. Often the problem is at the point where
the drain line attaches to the garbage disposer or household drain
line. If you remove this line, you can clear any debris from the hose
or hose connection. Be sure to reattach the hose before starting the
Your dishwasher pump ejects the water. The
pump is usually mounted directly to the motor, then attached to the
bottom of the dishwasher. You can reach the pump from inside the
dishwasher, but first you need to remove the lower rack, the spray arm,
and the spray arm support. Look for an impeller--a round plastic fan
blade-type of device that spins around. This is the wash impeller,
which forces the water through the spray arm. Beneath the wash impeller
is the drain impeller, which is similar in size and shape to the wash
impeller. The drain impeller pushes the water toward the drain port.
These components make up the pump. If any of the pump components are
defective, you need to replace them.
its probably leaving water in it and is clogged in the elecric pum or drain hose. somethins the pump has a rubber flap that will become lodged in the outlet port. this will cause dirty water to be left in the machine because of a slow drain. start by looking at the volume of water coming into garbage disposal where drain hose hooks up.
Check the drain hose connection at the sink drain for local blockage. If ok, you may have to tear down the lower spray arm assembly down to the deck (noting orientation and position as you remove parts). Look for clogged screens and clogged openings in the deck. You can use a vacuum hooked to 'blow' to make sure these openings are clear. Wash the screens in hot water, detergent, and white vinegar to remove water and food deposits. Make sure upper and lower spray arms have open spray holes and no split seams. Hope this gets you running again!
With nothing getting clean, the first thing to do is clean the filter and also underneath it. You will need to remove several screws and the lower spray arm to do the cleaning. Watch out for broken glass! Rinse out the filter as best possible.
Look carefully at the impeller to make sure it spins freely and is not damaged. While you are down there, look for any problems (brakes/damage) with the heating element.
Reassemble the filter and spray arm. Test with a load of dishes.
If problems continue, but the spray arms appear to be spinning well, the problem is most likely a failed heating element. Replacing it should make thing work much better.
Please get back to me with what you find. Good Luck!
Cleaning the filter was the right thing to try.
Since you don't see cracks/breaks on the spray arm and it appears that it is spinning freely, I doubt that replacing the spray arm will fix your problem.
If your dishwasher is several years old, your problem is likely a failing pump motor, but before you swap that out, check that the impeller is not damaged. Good Luck!
