MHWZ400TB00 Whirlpool Washer - Instructions

First unplug the washer. Make sure and drain washer completely. If not drained remove front panel , Remove 2.5 inch Plastic drain cover which has a catch bin on it. This will allow it to drain the washer. Put pan underneath to catch the water. Tip washer back and prop up with something 6 inches tall to get to the screws underneath. A cement block would work well. Use pliers to squeeze hose clamp together to remove the Hoses. Gently lift up The flip down cover Over the top of the wire harness Push in the tab on the wire harness, Gently pull back on the wire harness. Remove two mountings screws from the bottom of the washer. Slide the whole pump housing to the right and Lift up. Now the pump is been removed. Inspect inside the hoses For Debrie. Remove anything that is left in the hoses. Reinstall the pump in reverse order from the way you took it off. Leave front panel off Make sure all hoses and wire harness are hooked up. Run wash cycle to make sure there are no leaks. Do not put hands in while running. If no leaks replace front panel. Not sure if this is the right way But this is the way we did it and it worked well. Washer runs quieter now than it did when we got it

My dryer is on top my washer so I removed the dryer and pulled the washer out. I had to get rid of the water that was inside so I used my wet vacuum on the drain hose and sucked it out I then removed the front cover and the I tipped it back and removed two screws from the bottom of the pump bracket underneath the washer and moved the two clams on the pump hoses back to uncouple the hoses. I removed the pump and installed the new one and hocked everything back including the wires to the pump which is just a quick connect and pushed it back into place and it worked like new

I removed the three bottom screws and removed the plate. Removed the control panel, removed the star screw on the left side and pulled off the front panel of the machine. Loosen the bellow clamp with a phillips head and pull off the front spring clamp on the bellow. Pull off the old bellow and re installed the new one. Installed and tightened the bellow clamp and spring loaded clamp on the front of the bellow and re installed the panel, and control panel. Checked for leaks.

Just use the video. Shows you all you need to know. Very easy. Do it yourself and it saves you money.

I removed the service door and rear access panel to get at the bolts on the shocks and removed them one at a time. I did notice that the replacement shocks were heavier duty than the originals but was not an install problem. The machine is good as new now. A note, an appliance company wanted 800 to 1000dollars to diagnose and repair problem,i was able to do the repair myself for 70 dollars

I watched the video and it really was as easy as it looks. Great shipping time, I ordered the pump Monday and it arrived on Thursday, standard ground shipping!

I used the video at parts select as a review, then just followed it. Easy de-install, reminder there's water in the line be prepared with a pot or vase to hold the water. Easy install. Washer runs perfect now. As quiet as when we bought it. I always try to fix before I re-buy, not a big green guy but I try to keep stuff working and out of land fills. Also the part was at my door in 1 day, Awsome!.

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.

removed retaining ring on front gasket, pulled gasket back, took out door lock latch, unhooked wires, then reversed method to replace.

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.

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!

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.

Received water valve in three days, remove top on washer, removed old part and replaced valve with new one, real easy fix, any one could do this. PartSelect confirmed this was the problem and part I needed.

Took less than 5 minutes to replace, So Happy;-)

I found a YouTube video that showed how to totally dismantle the machine. I removed the top ( easy 3 screws). Removed the bottom access panel (easy). Removed the control panel (1 Torx screw and rather tricky to unsnap). Removed the door and hinge (2 Torx screws). Removed the below retaining band (easy). Disconnected the bellow at the front panel then removed the door lock mechanism (easy). Removed the front panel (easy). Removed the bellow clamp on basket side (screwdriver hose clamp type, a little tricky but not too bad). Installed the new bellow paying close attention to the drain holes being centered on the bottom. Assembled all parts in reverse order. The really tricky part was the bellow clamp on the front panel. Patients prevailed.
