This morning I heard from my salesman, Rudy, at Lowe's about my new washer and dryer.
The good news is that they will be delivered next weekend!
I explained my concerns with some of the reviews I read online last night and he was very honest that, yes, previous generations of these models had had some of those issues, but that they have been dealt with. The model I bought is on its 3rd generation and has only been out for 3 months.
I feel better! Still, I'm glad that I opted to buy the extended warranty--which I usually shy away from--just because it is a relatively new machine and I want to be covered for those 5 years.
I do think everything's going to work out OK.
