WFW8400TW03 Whirlpool Washer - Instructions

It took a very long time to attempt to diagnose the problem with this type of washer, finally was able to get the diagnostic to run and it said it was the Motor Control Unit (MCU). After ordering the part which was easy, it was not the reasoning for the problem and I still cannot get this machine fixed. Returned the part with ease, just waiting for the refund to go through.

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!

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.

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!

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

put in push down push back until they lock in

It was real easy. I disconnected the wiring as shown in the video. I took the clamps off the drain pump , once off I slid the old drain pump off. I slid the new pump on , attached the hoses with the clamp provided and connected the wiring. Just follow the video and you will find it to be very easy! Thanks Parts Select for saving me money

Just went by instructions provided by parts web site

The new drawer came and I took out the the detergent despensor piece from the old drawer and placed it in the new drawer and put the new drawer back into the washer. Now the front of the washer is complete. Good as new. Part also arrived in a timely manor too. Very pleased

Did not need to move washer, but had full access to left side of washer. side of water inlet valve. 1) remove 3 screws holding top cover on, on top back of unit. 2) remove 1 torque screw holding water inlet valve to washer. 3) remove 2 solenoid electrical plugs on inlet valve, noting hot and cold side. 4) using pliers remove rubber tubing by removing clamp. 5) install new inlet and follow steps backwards.

pushed knob straight on to shaft and then wife and I applauded!

I drained the water out of the pump area. Then took off all clamps and holding brackets. Next I pulled off the quick connect power plug. Then I put new pump in the way I took old pump out. The hardest part was unscrewing the bracket from underneath the washer. Cloth washer working fine.

Thank You so much for the other stories folks wrote on here! We were getting an F21 code on a regular basis. After finding a necklace and about $2.50 in change in the filter tray we found the problem. Over time I thought the washer was getting louder but it was so gradule that we really did not realize it.I had read other posts on here and ordered a new pump. After taking out 3 screws and 2 clamps the pump came right out and went in just as easy. Less than 15 minutes and we were back in business with a wisper quiet washing machine,Thanks Again everyone, Mike D.

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)

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!
