MHWZ400TB00 Whirlpool Washer - Instructions

After getting dress that wife denies closing in door out the repair wasant to hard. There are 3 or 4 phillips screws in back that holds top on that have to be taken out and the kick plate cover on bottom just snaps off but the rest is covered very well by other discriptions.(by the way the dress had to be thrown away so not only did i get to by bellow but a new dress also and the bellow was cheaper)

I watched the youtube video, then ordered the part from partselect. I then took my ipad out to the garage where I placed my washing machine and completed the removal of the old seal and installed the new one with ease. Be patient when you try and fit the new seal over the lip on the machines doorway. That was the only hard part. Once I got it started, the rest was easy. I am very happy the video was available and even easier to follow the link to order the part. Thanks! Presslerc

A previous person had broken the actuator switch connection so I replace it and got rid of the error code. But water poured out and I eventually took off the whole dispenser assembly and found a sock had stopped the big hose up where it enters the outer wash drum.

I purchased the downloadable Maytag Maintenance Manual (PDF format) and followed some of the directions and pointers from this web site. All in all, it was a pretty simple process. 1) Take the top off - 3 metal screws, 2) take the control console and detergent dispenser out - 1 T-20 Torx screw and multiple plastic clips and 1 wire connector, 3) take the lower panel off - 3 metal screws, 4)take bellows retaining ring off -- spring retainer used a needle nose pliers, 4) take off door latching mechanism - 2 T-20 Torx screws and multiple clips + 3 wire connectors, 5) take front panel and door off - 4 metal screws, 6) remove bellows retaining clamp with phillips screw driver, 7) remove old bellows. Reverse the process to install new bellows. On installation, make sure that bellows drain holes are at the bottom of the door. Also, hardest and most time consuming part was installation of the metal retaining ring (spring retainer) fought with it for about a half hour before I finally got it on. BTW all metal screws for my machine were 1/4" head the remainder were all Torx T-20. Good luck!

Unplugged washer first! Removed front bottom panel by removing three screws, unscrewed the Drain Plug assembly by turning drain plug counter clockwise with a bucket to catch excess water from washer. Used pliers to remove spring clamps from washer agitator drain hose and then removed the spring clamp from the hose going to drain. Checked hoses for obstructions, then Slide Drain Pump assembly up to the right to remove. Then installed new Drain Pump assembly by sliding pump into slot to the left. Connected the agitator and drain hose to new Drain Pump and fastened with spring clamps. Plugged in AC line cord and turned washer on and started a quick wash cycle to check for leaks and to see if the water drained from washer properly. The water drained from washer and error code did not appear. The error code F21 reappeared during the second wash cycle. After closer inspection with a flash light, I found a large piece of cloth caught between the washer agitator and washer tub covering the drain by shining the flash light up towards the Agitator tub. This was solved by removing the Drain Pump assembly and all of the drain hoses again. Then removing the the large hose from the agitator tub and then removing the large piece of cloth from agitator tub. After reassembly, the washer worked like new!

Searched internet for diagnosis. Ran diagnostic test using the diagnostic manual from whirlpool. The error code was F29. Replaced door latch but problem was not solved. Then order the Motor Control Unit. Removed old control unit through the top by removing the top washer cover and numbering harness positions with painter's tape. Install the new Control Unit and ran diagnostic procedure. The problem was solved. The washer is working fine.

First, I looked at a replace bellows video on U-Tube that saved a lot of time in knowing how to proceed. You really need nutdrivers as sockets won't fit on the screws. Fitting the bellows on the large drum is not as simple as it appeared in the movie. It took several attempts to get it in place, but it was simple to place the clamp after it was there. Other than that, just follow the steps in the movie for your model

First I removed the bottom panels then the door then the top then the front control panel, I had to go to different web site to get directions on how to do this, after you remove screws you have to unplug U18 from electrical control box. Then remove bumper, find wire around front of bumper and remove using needle nose pliers, then remove back of bumper from tub using phillips head screwdriver. Then with help we replaced with bumper. and put the machine back together. My complaint is there were NO instructions in the box with the bumper and the ones on your web page are not detailed enough. I had to search the web "how to remove maytag door bumper" before I found how to remove it.

First unplug the washer and take the back cover off. Loosen the screw on the motor and the big nut on the belt wheel. Take the old belt off and put the new belt on around the motor but slip the motor back in place with the screw slightly in place but do not tighten it yet. Place the belt around the motor and the wheel but this is hard because you need some one with some strength so the is where my dear boyfriend came in handy. He used his strength to stretch the belt and put it back on the machine so I could put the big nut back on. But if you break a wire you have to know a little electrical to put back the wires back in place with small connectors. I do know electrical also. My machine is working better like new. Carol Rozier

Got parts in mail. The new parts seem to be better than originals. Remove bottom front access panel to reach shocks. Revove nuts and bolts from bottom mount. Then remove any existing pieces from top mount. Twist in new shocks at top (this part was why I put the bit difficult. Sme were hard to twist.),then pull down and put bolt back in bottom mount and tighten back up. re-install front cover and clean up.

Perfect part...saved me hundreds on labor. Thanks!

took the old part out by the front panel and put the new pump in and now it works great. only took a couple of minute to put the new one in. thank you for saving my washer.

Very easy. Revived back of washer. Used a screwdriver to pull belt over pulley. Very easy

Well first of all when you buy this washer, the salesperson should tell you about checking the drain catch (ahead of the pump) and emptying out whatever get's caught in there. Never had a clue until it wouldn't work, then did a search on the internet, and darn if I didn't find specific instructions on how to open and clean out. Mine was packed full of hair pins, small change, lint, buttons, etc, all kinds of stuff. Guessing that is why the pump went out in the first place, it was so packed full that the pump could not draw any water through. But even after I cleaned it out, the pump was already shot. So called a service man, he said the pump would cost me around $200, then his labor to put it in, plus a $68 service call to just come and look at it, and $68 when he comes back to replace it. So I searched the internet for how to replace, came up with a very detailed You Tube video on how to replace Whirlpool Duet Pump. So ordered my pump from PartsSelect, just over $100, and replaced it myself. Super easy, only about 5 minutes. Thanks! —A very determined housewife!
