My wife was using the less expensive "store brand" fabric softener and she noticed that it was leaving the reservoir prematurely. She started using name brand,Snuggles, etc and it has worked like it is supposed to.
I think because the el cheapo brand is too thin,watery.
Make sure the dryer filter is cleaned at least every two drying cycles. The water filter(lower front bottom) should be cleaned regularly. We have had our Splendide since 2002 and she loves it.
It wasn't drying properly last week and she gave me the "Git" alternative. "Git fixed or git new". ORRR I will go to the laundramat.
It got fixed.
