MAT12PDBBW Maytag Washer - Instructions

The job went fast an well

The motor was easy to replace: unplug the wiring harness, slip off the belts, release the tension springs from the motor carriage with needle-nose pliers, and then unbolt the motor carriage with socket set and remove from the washer. Remove the pulley from the old motor with allen wrench and transfer the carriage to the new motor. Reverse operation for everything and you are back in business. The hardest part was the far back screw holding the carriage, a wobble extension helped.

First, I secured one lid hinge ball in its appropriate position between the lid and the washer. While keeping the first ball in place I placed the other lid hinge ball as close to its intended position as I could get it. Next, I pushed the lid and ball into its position.

I took out the two screws in the bottom front panel of the washer, and rotated the front panel from the bottom away from the machine until the top or the panel was released from the machine frame. I then tilted the washer back to get access to the bottom of the machine. The pump pulley had split in half, and the bottom half fell off the drive motor shaft. The only problem I had was breaking free the set screw that holds the pulley to the drive motor shaft. I used a long arm Allen wrench and an adjustable "Cresent" wrench to apply enough force to break the set screw loose. Iclamped the upper transmission belts tightly to keep the motor shaft from turning while I loosened the set screw.

Replaced lid switch assembly. Unplug washer. The console on this washer can be removed without sliding the washer from the wall. Just lean over the drum. Three phillips screws along the top, two machine screws removable using a small socket. Move the console forward to view the lid switch in the middle. Disconnect switch plug. Pop lid switch and plunger out. (Both part of lid switch assembly.) Replace. Connect plug to switch. (Could plug washer in and test at this point. Unplug.) Reassemble.

Replaced the 2 belts according to instructions received with the belts. Very easy repair

Found a very stretched, loose pump belt. Was able to pull it off pump pulley and motor pulley easily. Pushed motor assembly toward transmission pulley and removed wider drive belt. Wiped all pulleys clean. There's a double on the motor- one for drive belt, one for pump belt. Removed two hoses from pump using nutdriver. Removed pump. New pump installed. Installed two hoses on new pump. Installed drive new drive belt. Installed pump belt last. Slid pump to near farthest spot in slots. Tested for correct tension by pinching pump belt. Should be able to pinch center so two pump belt sides come within 1/4" of each other just as the spring tensioned motor mount starts to move. Pused washer back into place after external hoses connected. All new hose washers and filters on both hot and cold. Ran, checked for leaks - none! Absolutely perfect. Put front panel back on. No weird noises and drum empties perfectly every time. My wife is so pleased she's doing more loads.

Used toothpick for a year to push switch acctuator far enough to engage switch. Broke my foot and found time to order part thru PartSelect. Went from cast to boot and received part 2 days after ordered. Had difficulty with foot and getting to switch. Went back into PartSelect and figured out how to dis-assemmble panels thru the diagrams. Time on my job doesn't, just that their service and expertise that is available to everyone is there to use. Broken bones or not, I will always get my parts and advice from PartSelect. Thanks to PartSelect.

I was told that it might be a clog in the tube.. we check the tubes that wasn't it Then I Google it and was told it might be the drain pump. I was just glad that Part Select had what I need because my machine is over 20 years old. We change the pump and now I hope I get at least another 20 years out of my machine. I will always use part select to get my parts. Thanks

Unplugged washer, turned off water supply,Removed the screws in back of console. removed. back plate, unplugged lid switch from console. removed screws holding console to frame of machine. Removed lid by prying the bottom corners out freeing the hinge ball on either side. unscrewed the lid switch from the frame of machine. installed the new plunger screwed into place aligned with lid switch snapped new switch in place, plugged in to console. put screws back into console and put back plate back on turn water supply on plugged in washer started washer which is now working . and the repair guy who never showed up wanted to charge me 50. diagnostic fee when I told him itwas the switch. it cost me less than 50 for all the parts. if you can read you can do

Drum on the Maytag washer was not spinning is a true rotational pattern. Adjust or replace the centering springs.

How-to-description
I had to hack saw off the centering springs eye bolts since they were rusty and not adjustable. If you have to cut the old eye bolts as I had to, be careful... the spring will jump up an inch or two very quickly and you want to keep your hands clear. It makes a load noise and my wife asked "what happened". Not a big deal, just be aware of the spring returning to a normal state.
Place the new eye bolts in position and tighten the nut with 4 turns. With duck tape I held the eye bolts in place from under the machine. Had my son push the drum towards the replaced spring to shorten the length of the end of the spring to the eye bolt. Stretch the new springs with a long screw driver, one end against the washer body, and the other end near the handle. Pulled down on the scrw driver until the spring can hook onto the eye bolt. Before cutting the old eye bolts I measured the length of the eye bolt from the spring to the frame. Adjust the new eye bolts to the same length after the spring is stretch onto the eye bolt. Overall a simple project, cost $40 for me and the best advice is using the long screw driver to pull down on the springs.

I deduced the lid switch was the problem.

I removed the two screws holding the control panel on. Pulled the control panel back.
Disconnected the ground wire of the lid switch.
removed the two top clamps that hold the panel to the top of the machine.
Pulled back the casing (outside of the washer) and placed it on it's side on the floor. Here I could reach the switch. Removed old, installed new and reversed the process.

The part that gave me the biggest problem was setting the casing back on to the frame. You have to slide the front part in at the bottome, then lean back the rest of it.

Determined the tub seal was bad and ordered the seal and tub bearing. Removed the front cover with two phillips screws and unbolted the top to lift back. Removed the agitator with 1/4" setscrew on side and lifted out. Using punch and hammer, broke the inner tub nut loose (clockwise is off). Lifted out the inner tub, unscrewed springs from the bottom and removed; then removed the bearing with a little prying (had to raise the tub slightly and tap the center splined shaft to push out) and lifted out the outer tub. Outer tub had few rust spots about to penetrate, so sanded off rust, primed with etching auto primer and sprayed enamel topcoat to prevent further corrosion. Reassembled in the same order.

When done, there was still a loud noise on the spin cycle, so obtained a spin bearing and brake assembly (need to replace both most always). Tilted the machine on its back and removed the pulley, then put a special wrench on the brake assembly and broke loose (counterclockwise) with a 3 foot extension after placing a 2x4 section in the tub between wall and one of the bases for the spring arms (to keep the tub from turning). When the brake came off it was full of water and corroded from the leaking tub bearing previously replaced. Reassembled in reverse order and replaced two belts on the bottom for good measure. Works perfectly now and is very quiet.

In my estimation, the repair should have included both the tub bearing/seal and the spin bearing/brake assy from the outset. Could have used a chain visegrip wrench instead of special tool to remove the brake assy - whatever is available. The tool costs a lot and will never be used again.

Put blocks under the washer where the leveling leg was needed and screwed the part into the washer. Then it was just a matter of moving the washer into place and leveling. Pretty easy.

removed old pully, put new one on with hex driver, removed belts, put new belts on and finished.
