MHWZ400TB02 Maytag Washer - Instructions

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!

other than needing a new type of screw driver (not philips or flat head, but rather a starfish looking thing), the replacement was simple. took 5 minutes (after finding the correct driver)

unplug washer from outlet carefully tilt back to get at underside of washer remove bottom panel. pump location lower right front. remove two hoses from back using pliers keep note on hose location. remove two bolts on underside of machine slide pump to the right to release from rubber holders to install reverse the process also good idea to use the new hose clamps that come with your new pump and the rubber mounts if they are included

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!

Unplug Unit, remove lower cover screws with screwdriver that has 1/4 drive at end, put 2 gallon bucket at strainer remove water. Remove inlet hose clamp and outlet hose clamp, disconnect pump motor wiring plug, aggressive push to RIGHT popped right out. put a dab of Vaseline on new units rubber base slide back in reverse order. Plugged in check for leaks put back together, Repair took less than 15 minutes, working great! WHAT I FOUND IN STRAINER: LEGO'S-CHANGE-PAPER CLIPS, enough things to destroy the impeller !

The only issue I had was getting the hose from the tub re-installed, but that was my fault, the pump went right in. It couldn't have been easier. I was very pleased, received the replacement pump in just a couple of days, packaged very well for shipping, and had it installed in a matter of minutes. It took longer to take off front panel to access pump than it did to install it. Very pleased with "Part Select".....will use again!

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

Had my appliance man do it. It was the first one he had ever done in 20 years of working on Whirlpool. It was quick. The parts I received from you were cheaper than his supplier. Needless to say that made me very happy!

First thing, unpluged the washer. I removed the lower front acces panal. I then propped the washer up on 2 pint sized paint cans to reach the pump mounting screws. I disconnected the wire bundle going to the pump. Then removed the inlet and outlet hoses from the pump. Then I removed the 2 mounting screws on bottom and slide the pump to the left and removed. I then pump the new pump on the same way I took the old one off, but in reverse. Easy and fast the worst part was the price of the pump.

Just follow the repair video and you are good to go. Very easy my 16yr old did it.

First, I watched the video again just to make sure I had a firm grasp of the task ahead. I gathered up the tools and proceeded to begin. First obstacle: getting the washer tilted back enough to put the blocks under the front feet. The washer was sitting inside a square water pan with a drain connected directly under the middle of the washer. Therefore, the water pan did not move and I could only get the washer moved out far enough to 'barely' put the blocks underneath. Second obstacle: a clump of hair had gathered at the bottom portion of the door unnoticed and caused a slow leak from the bellows. This leak dripped down and rusted out two of the three screws. I had to use a socket set to get the screws out. Third obstacle: getting the pump removed from the bottom of the washer. With the drip, the pump had stuck to the bottom of the washer. Trying hard not to get cut on the sheet metal bottom, I pushed and pushed and pulled until finally the pump let loose. From that point on..smooth sailing just like the video. Washer fixed!

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

I had to replace the bellow to the washer because I discovered the leak was from the door and bellow area, only problem I really had..... was installing the bellow on the outer drum, I applied a coat of hand soap to make it easier to secure in place.

Put towel down to catch excess water, opened drain screen, used pliers to remove squeeze clamps on both hoses, removed front hold-down torx-head bolt and slid pump assembly out. Compared new part to old and found 2 differences 1:no hold-down location in front for bolt,2: the rubber padded feet are not the same. I was able to remove the two screws on the right side and use just the rubber pad for support while sliding the left side in the slot and is was plenty stable and works just fine. I guess the Whirlpool Duet model is a bit different on mounting but everything else fit quite well, the washer is working perfectly again.
