The fabric softener dispenser is not emptying after the cycle has completed.

Where are you putting the fabric softener and when do you put it in? If your washer has a fabric softener dispenser, use it at the start of your wash. Leave the lid closed until cycle is completed. No dispenser? Pour diluted fabric softener in the rinse cycle or the second time water fills the washer.

THAT PART WILL NEED TO BE REPLACED

Check to see if the line is plugged up.

Purchase some fabric softener and place it in its normal location at the beginning of the cycle. At the end of the cycle check to see if fabric softener has been dispensed and whether there is water in the cup.

If the fabric softener is gone, but there is water in the fabric softener cup, then your problem may be with the water valve assembly. The water valve assembly (as one complete unit) has a separate solenoid for hot and cold water temperatures, bleach and fabric softener. The fabric softener solenoid on the water valve assembly could be defective (allowing water to fill the fabric softener cup).

Contact an appliance service company.

Hello. This is a common problem due to the fact that fabric softener collects in the dispenser and gums it up. Begin with an empty washing machine. Add two cups of vinegar to the fabric softener dispenser and then run the machine on the maximum water and hottest water setting. Once the cycle is complete check it out. It will be as clean as a new machine. If this treatment didn't completely clean out the dispenser, repeat the cleaning a second time with two more cups of vinegar. regards, Joe
ps - kindly rate my answer as helpful. Thanks.

my son had this same problem and when we took the dispenser out and checked the hoses they were clogged with semi hardened fabric softener that didn't pass through. they always used a warm wash with a cold rinse and since i told them to use a hot water wash with a cold rinse at least once a month they have not had a problem. hope this helps.

Try putting in less softener.

di you try to remove the drawer completely and check for a blockage under he dispenser itself.(sometimes te fabric softener can get kinda gunky.. if you extend the dispenser you see a little black tab in top left corner, push it down and dispenser will release, just in case you didnt know that

I'm sure you heard a small motor running from time to time during a cycle. That moves an "arm" which sends water to the different chambers during a cycle. Fabric softener is dispensed when water goes to that chamber and dilutes the fabric softener. That chamber then empties by a siphoning action.
If you want to narrow down the problem a little to help trouble shoot -- put some wet rags in and run the Rinse and Spin cycle with some fabric softener. If the softener is not dispensed, then you know that the water isn't being sent to that chamber properly.
If you are intrepid enough to take the top off your washer, do that and see if the arm appears to be moving during a normal cycle. Maybe the arm got dislodged or broken during the move.
If water isn't being diverted properly, I think this calls for a real repair person.
