I've got a frigidaire stacked washer/drier combo unit that is acting up. The drier works fine, but the washer will fill, agitate, then just stop. It won't drain the water out of the tub. I have tried clicking the little dial through the wash cycles manually, but it still doesn't do anything. It just stops. The washer is nothing fancy, no digital buttons or fancy controls, just a regular washer. Does anyone know what is broken or how to fix it? It's still under warranty, but they will only cover parts. Plus, there is a $50 charge for them to even come out to the house. By the time I add labor I'll be looking at a charge probablly over $100.
