My 24 year old Sears Kenmore washer and dryer have never needed repair and still going strong after about 3500 loads. I think I paid $500 for the pair so that comes to less than 6 cents a day or less than 15 cents a load.
We may have the same set as ours has been working for 24 too. Our neighbor has gone through three since we purchased ours but Sears changed their manufacturer - low bidder.
