maytag front loader Model MHW6630HC0 is 4 years old and it quit dispensing fabric softener. It dispenses it once in a while, but, most often not. It, also, makes a sort of grinding noise that seems to be coming from the top of the machine at the rear left top corner. I suppose that is where the mechanism for the dispenser would be. I'm wondering if it has gotten plugged somewhere. We have some cleaning cloths that produce quite a bit of lint and think that may have been the cause. Otherwise everything else works fine.
I thank you in advance for any help you may be able to provide.
