MAT12PDDBW Maytag Washer - Instructions

Tilted the washing machine back at 45 degree angle. Removed three screws from the underside of machine. Slipped belt off pump. Lessened two hose clamps and removed hoses.
Lifted old pump out. Dropped new pump in place.
Screwed in the 3 screws. Slipped on the belt.
Attached two hoses. Tightened hose clamps.
Set washing machine upright.

No more leak.
My problem was I could not prove the pump was the source, but after switching it out I have had no problems (good enough).

That would take forever to write in everything you have to do, but I did go to a website that had the steps you must do to complete the repair. You can google tub seal kit and mounting stem and the brand of your appliance and i'm sure you will come across the steps to complete the repair. I would advise you to first order a spanner wrench it makes the job much easier and you really can't complete the job without it. So do that first and then take the machine apart if you suspect it's a tub seal leak and then order your parts. if i had a spanner wrench available to me from the beginning it would have gone much smoother from the start.

remove front, 2 screws hold top down, 1 screw holds adgitator on, hammer and punch to remove stem nut (clockwise) used wd40, lift tub out, hammer and punch to remove stem (clockwise), pull seal off, put liquid soap on seal and reverse process, no more leaks!!

For the most part, I followed the excellent repair advice already available on this site for installing these parts. Especially useful was the caution that the threaded pieces had "left hand" threads and to loosen them they had to be turned in a "CLOCK WISE" direction. My washer is 9 years old and due to calcium deposits on the threads, I did have some trouble with loosening the large retaining nut. I first soaked the nut for a few hours with a rag soaked with white vinegar. This removed some of the calcium but I still was unable to undo the nut. Finally, I soaked the nut overnight with penetrating oil and WD-40. The next morning I was able to loosen it using a drift punch and medium sized ball peen hammer. I only had one difficulty. Maybe it wasn't necessary to do so, but I wanted the rubber boot seal to be seated pretty close to the surface of the inner basket. This turned out to require more downward force than I would have expected even though I installed it dry, without use of any type of lubricant or soapy solution. Now, two weeks worth of washing and not a drop of water seen underneath the washer.

first i removed front panel by pulling it from the bottom and then removing the top. then i removed the agitator with a 1/4 nut driver. then i had to open top lid which is hinged and held together by two 1/2 inch bolts. after i opened up the top of the washer i had to remove the white plastic top of the inner tub. in order to remove the inner tub there is a large nut that i had to use a punch and a hammer to break it loose. don't forget this nut is counterclockwise to loosen.hint use a little wd40 due to calcium build up around nut. once the inner tub is removed you should see the rubber bushing. be sure to remove all rust and water calcium build up before installing new bushing. i used a wool pad. put everything back together the way you took it apart and it should fix your leak.

The task to replace the tub seal would have been relatively easy had it not been for the need of a special spanner wrench to remove the nut securing the seal. Instead of purchasing the one time use spanner wrench which was only available on line and would have delayed my repair I elected to cut the putty metal nut off with a cutting dremel tool. This was a delecate process to ensure one did not damage anything else in the process of cutting the nut. Once complete a set screw, pipe wrench and common screwdriver, hammer and tap punch was all that was used. Easy process from removal to installation and the leak was fixed saving significant $$$ over having a "maytag repairman" perform the fix...parts select video helped describe everything and cost while not cheap was significantly less for an adept DIY customer.

A tension sping on the motor broke, smoking the drive belt.
step1...remove front of the washer to access spring, tip washer back & prop on short 2 x 4 board. 5 minutes
step 2... remove one end of pump belt to get new bely up to drive pulley put on belt using fingers only & replaced the end of the pump belt....2 minutes

step 3...put new spring under motor & hook one end in attaching hole on motor, reach through with pliers to grasp spring to pull end to attach spot on base...1 minute

It took longer to open up the washer front & prop it up that it took to repair it. This is a siper easy repair!

Disconnected power to washing machine then took off back panel. Located "Lid switch", disconnected lid switch wires, pushed lid switch toward front of machine to remove.. then replaced with new, reconnected power wire to lid switch, reattached back panel, plugged power back in.

There is one good description already posted. I would add:1)If the the nut holding the inner tub doesn't loosen easily just split it with a chisel and don't waste time. 2)Don't order extra washers to remount the outer tub, they come with the bearing! 3)While disassembled I ran the spindle on spin to make sure the brake assemlby wasn't the problem. It ran quietly and smoothly. 4)The inner bearing sleeve was stuck on the spindle and didn't want to free up. I used a rotary tool to cut a groove in the old bearing sleeve then chiseled on the groove edge and it split nicely. It was very brittle. The washer seems to work well now. Next time I see a leak I am going to repair it right away!

First I removed the two screws that held the front panel in place. Then I determined that the belt for the pump had fallen off because the drive belt was worn (and inverted) and a piece was hanging off and causing the pump belt to slip off the motor. I replaced the belt for the pump (Temporarily) to allow the tub to drain.

I replaced both belts with new belts and returned the front panel. The process took 15 minutes due to the necessity of explaining the proper use of tools to a neighbor child and allowing him to assist (required for the completion of one of his Cub Scout requirements).

The hardest part was figuring out how to get the front panel off of the washer. Once that was done, the pump came off easy.... 3 screws attached it to the bottom panel and 2 hose had to be disconnected. Putting the new one in was easy.

1st We pulled the washing machine from the wall and unplugged it. 2nd We tilted the maching back against the wall so that we could see all the pullies. 3rd. We removed the two screws that afix the front panel on the lower part of the washing machine and removed the panel. 4th We removed both belts and put new belts on. 5th We put all parts back in place and plugged maching back in, slide it back in place. 6th It worked like a charm and I proceeded to wash 3 loads of laundry that evening. The only tool we needed was the phillips head screw drive to take off the front panel. It took us 5 minutes to fix the machine.

Wish there was a video. I am above average handy but this one- I might just pay someone next time...The tape on the threads was a great tip but took a while to understand what they meant by putting tape on the threads. Scraping off the old pads is easy for the front one but the back pad and a half is so hard to reach to really get it cleaned. Bruised and cut knuckles on that one. Then not having the glue for the pads was a surprise and you have to get a good contact type cement that sets in 10-15 minutes or you will be waiting hours to put it back together. It was easy to put the first spring on, then the second and third got harder and harder.

Well, I figured out a couple of things during this process. #1 The Washer was smoking. It had happened before (a sock got suck between the basket and the tub) so I assumed that happened again. I couldn't see anything in that space this time, so I dissasbemled the washer to see if any clothing was there. Relatively easy once finding the screws to remove the front panel. #2 What I found was a sock in the pump box. I disconnected the hoses and removed it, saw nothing between the basket and tub and ran it to see if problem corrected itself. It still was smoking. That is when I checked the belts, #3 first the pump belt, replaced it, very easy, just pulled the old one off, and wheeled the new one on. It still was smoking, #4 so I replaced the drive belt, very easy and the same as the pump belt. It still was smoking so I lubed the wheels for the belts, and #5 cleaned the residual rubber around the wheel from the old, fried, dry rotted drive belt. No more smoke!!! However #6 remember to leave space between the basket and the top of the tub, as when I put the washer back together the basket didn't spin. I removed the top and ran the spin cycle, it spun fine, reconnected and it didn't spin, the tub top was touching the basket, that's when I relized the top was on too tight. I reattached and left about 1/4 in of space and all is well now.

removed screws on front of washer, removed bolts holding top cover hinged back, nut driver to remove agitator, slipped agitator off, removed tub hoses, did not have special wrench to remove large nut on shaft, used punch and grinder to removed, had new large nut so wasn't concerned about damaging old one, pay attention to thread pattern to know how to turn, if you had special wrench job would be easier, removed spring bolts and took out inside drum and tub. cleaned corrosion and installed new seals, can be hard to slip on new seal, don't use grease, get dishwashing soap to use as lubricant to put on. Put back together and all is good.
