Whirlpool Duet washer not emptying fabric softener from drawer

4 posts in this topic

Whirlpool Mod#WFW9400SW01 does not empty fabric softener from drawer in normal wash cycle and fills the bleach compartment with water.

I cleaned the drawer and the overhead distributed holes to no avail. Is there a way to test the distributer motor with the plastic arm that moves directs the water and/ or the main controller to see if the signal is getting to the distributer? I have a meter and the know how to use it.

There is an automated test program in the technical sheet located behind the bottom access panel.  This program will test all the components including the dispenser actuator.  Make sure the dispenser cam arm and spring are intact.  Make sure the drum is empty and the unit is turned off.  Execute the following steps in sequence to access automated test program:

 

1)  Close door.

2)  Push Power.

3)  Select the Drain and Spin cycle.

4)  Select No Spin option.

5)  Push Prewash option within 5 seconds.

6)  The automated test program starts. (Not possible to skip steps)

7)  To cancel test program press the Stop button.

Thank You PDUFF,

I bench tested the dispenser motor and contact,

With the top of machine off I can watch the dispenser motor work the arm and go to different positions, however I still have fabric softener left in the dispenser drawer.

I will go through the tests that you recommended.

Update :

 

Performed tests...

 

Everything in the dispenser area is clean and operational.

 

It appears that there is not enough water volume/pressure going through the distributer nozzle to flush out all of the fabric softener section, although now the bleach compartment is completely emptying. I attribute this to cleaning the overhead distributer holes, but although that improved the situation it did not completely solve the problem. I still have residual softener mixed with some water after a wash cycle...Like there is water reaching the softener area, but not enough. I can see it just barely dribble out of the overhead distributer when the nozzle is directed to the fabric softener zone.

 

I really suspect that the water valve assembly is not allowing sufficient pressure through the seats, perhaps due to age and swollen rubber orfices.

 

What is your thoughts?

 

Thanks.
