This machine has a floating basket. You should be able to grab the inside of the inner drum and lift up. The basket should lift up 2-4 inches (just an estimate) and then drop down freely. If the tub will not slide up and down as decrived above then the tub is stuck.
You will need to replace the shaft and bearing kit.
You can use jays cabrio tool to remove the inner basket.
If the basket can move freely, then replace strut kit.
Both the all dolly and Master Samurai Tech course will make you money.
What you need to ask yourself is,
How often would I use the all dolly? (I'm guessing 2-3 times a week max)
How often would I use the knowledge from the Master Samurai Course? (Every Day)
It seems like a no brainier. I highly recommend the fundamentals course even for experienced techs. You can always learn more. You also can forget troubleshooting techniques over the years. Even if used as refresher course, it's worth it.
I myself have learned from the course and I have been doing this for 10 years.
At this point the issue the customer notices is the refrigerator compartment is warm due to the evap fan iced up. The plugged drain makes the moisture circulate through the evaporator and freeze up the fan.
Defrost evap and condensate drain and also install a drain probe.
Oh and be careful removing the evap cover. If you crack the foam when removing, then you have to replace the cover. If you don't replace it after the crack then you will be back again for the same issue of the fan iced up. Except this time it is caused by the cracked evap cover.
(Some techs just automatically replace the cover any time it has to be removed. )
As maps said you simply have no choice but to replace the whole assy. The pump motor is not offered as a separate part. I wouldn't waste any more time searching just replace with a Part number: 280187
1. Is the light turning off when the door is shut?
2. Has the duck bill been swapped out to a P-trap. (This is more a preventative maint. thing, probably not causing this issue unless someone has removed the duck bill all together. You would probably find more frost than what your seeing if the duck bill was removed)
It will go into diagnostic mode even if there are no error codes. Do you have the fast track manual? That's what you want. It states at the top how to enter diagnostic and forced mode. It's just two buttons you hold to enter diagnostic mode.
Check your defrost condensate drain. When it plugs the fan circulates the moisture and freezes the evaporator up. Also causes the evap fan to stop running.
Also do a search in the downloads section (and forums) about your issue. There are many threads (check service bulletins too) pertaining to this problem.
Have you put the washer into diagnostic mode? This where you will retrieve the error codes that have been stored. You can also run automatic and manual test modes. http://appliantology...er/#entry260242
Before going further with the manual search, will the WED6400SB1 also work for my WED6400SW1?
If it will, then I have the tech sheet and parts list I need.
This is where the work starts. What you have to do is go to a site where you can do some cross referencing. I use APP. Look up both model numbers and then pick a part that would be a main functioning and unique part. The main board would be a great part to check between the two models. If the main boards are the same then the manual should be compatible.
