Maytag dishwasher legacy 300 quiet series

I was so impressed with the advice on this website, I thought I would take a stab at this. The difference is, I will include all the steps, so if I go into a little too much detail for you, I'm sorry, but I felt a few things got left out that needed to be said.

Tools Needed: screwdriver with t-15, and t-20 torx bits (available at any hardware store), and a pair of pliers. Also I used a headlamp so I did'nt have to hold a flashlight with my teeth.

step#1- Clear a spot on your counter or kitchen table and remove both the lower and upper racks from your dishwasher. The lower rack just lifts out, the upper you will find two light blue plastic caps that once removed will allow you to slide the rack off of the metal slides. Next, the long L shaped spray bar that goes up the back and across the top needs to be un-clipped and removed, 2 clips at top and 2 clips at the back. It might take a little wiggling but that spray bar slides into the top cover, once unclipped push back at the bottom and tilt the upper part toward you, it should come out fairly easily and give you wide open access to the cover. Next you want to remove the plastic nut that holds the spinner in place, using your pliers turn it counter clockwise, it should loosen fairly easily, and remove nut and spinner. Next with either a T-20 or T-25 torx bit, remove the 3 screws that hold the outer cover in place, notice the direction of the tube that plugs into the spray bar, make sure it goes back in the same way. Now remove the T-15 screw that holds the black grinder cover in place and remove screw and cover. Now remove the 6 screws that hold the inner cover in place and remove the cover. You can now see what all the fuss was about, mine included a piece of pistachio shell, a bay leaf, and a cherry pit. Once it's all cleaned out, just reverse these steps and be ready! You have just earned your place as your homes resident handyman or woman!

I have Model MDBH970AWW Quiet Series 300 Maytag dishwasher, started making a strange and sudden sound that wasn't "normal" Took out my six-sided (not Philips) tool, removed spray arm by hand, eventually got to the bottom of the tub (remember how and where all the screws go and in what order). I found a small nail, and a tooth pick which must've been moving in a circled fashion, all the while "chipping" away at the black gasket, hence the black floating particles or stuck to the sides of the tub. Granted the tooth pick must belong to my husband, but the 1 inch nail - dishwasher came with house and was 2 yeats old at the time. At any rate, these were removed and all the dirty food-filled water was removed. Apparently the tub hasn't drained 100% everytime. At any rate, the washer now runs quiet as it should and smells as good as new. DMA

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.

If you take a series of photos with your digital camera as you dismantle the dishwasher ( or whatever ) you can see where the parts go when re-assembling things

Like they all said...removed the arm( small cap nut-removees CCW as any usual nut), the plastic cover (3 larger screws), then tipped it back enough to remove the inner top cover then unscrewed the black impeller (small circular thing with 
one screw in the middle) then removed the bottom plastic housing.  At this point you can see the cutter blade and the channel which will have the junk floating around causing the problem.  I found a rubbewr foot off a cutting board and a plastic piece of a bird feeder.  Shocks me that this little stuff made sucha hugh sound.  Be sure you get it back in the same orientation.  The bottom plastic must align to the drain in th erear...mostly if the screwsa align then it is right.

Don't let this scare you...easy.  Just don't rush and over tighten the screws.

I cannot program a time delay all of a sudden. Couldl it be that the switch has gone bad. Is this an easy fix

Thanks for the tip! Same grinding issue on my Maytag Quiet Series 300. Easy to disassemble, but I had to do it twice! First time, I found a flat plastic bread package clip and thought, "aha"! But when I re-assembled it, same grinding sound. Disassembled again and found two other small wooden pieces I hadn't seen before, reassembled and "voila"! Back to quiet. So a word of advice - when you're in there the first time, look hard to make sure you find all the foreign matter!

Miss Midgit's steps were great - however, if you un-clip the "arm" from the back and top - goes faster. After it is unclipped, tilt it forward. Found broken pieces of black plastic and a Corelle sticker - we don't own any.

Ran a test run and it still stopped at 38 minutes. Husband asked what the High Temp Wash was - did not know and did not set. Finally figured out that once it gets to 38 minutes and water temp is not high enough, it stays at 38 until water gets hotter, then goes on it's merry way to count down.

Just fixed my Maytag Quiet Series 300 using the above steps to disassemble the spinning arm and other inside tub stuff and found a screw and a few small chicken bones and such...   That was it- it "sounds" like this dishwasher is succeptible to small particles getting down into the inner workings that cause some noises-maybe common to all dishwashers- I don't know I am not a repair guy- or at least not on most days...today I am as well as totally impressing my wife... Thanks!!!!

The solution works perfectly. I found a large plastic piece and a few other pieces of junk. The whole repair took about 40 minutes.

Maybe stupid question, but do you have to cut off the power supply when going inside the dishwasher for a problem such as this?

Please help! Can't get clips to stay on back and top of dishwasher when reassembling! thank you!

This solution "sort of" worked for me. I took apart the lower assembly and unfortunately found that my impeller was damaged and the plastic pieces that were causing the occasional noise were actually from the "neck" of the impeller where the screw held the impeller in place ... so I have to order a new impeller to see if this totally corrects my problem but I'm sure it will - I'll report back in a few days when my kitchen "project" is reassembled with the new part (appliancehelp.com and appliancepartpros.com were two of the better sites I found that actually included diagrams of all the parts in my appliance on their website - and I ordered for them as well).

Thank you Miss Midget! I loved being able to fix it my self instead of having to bug my husband when he got home with another project!
ps - digital camera idea was awesome - I took a pic at each step!

Same grinding sound issue on my Maytag Quiet Series 300 MDB5601AWW. This was a relatively simple fix with a couple of Torx bits (T-20,T15). Removed a toothpick and a the remains of a couple of rubber feet from my cutting board. Working fine now.

Thats interesting.. i just pulled a nail out of mine also...
Not one of my nails... weird looking small gauge but long. They must be leaving these things inside.
