Our tax return came and my husband's first words were "I want to buy a new dishwasher." He was serious, but kidding, for he knows that buying new is not necessarily better. In fact, when it comes to appliances, we sometimes wish we kept our old ones.
Our new/used stove: We had an old electric stove, bought second hand, with the coil burners. It worked just fine, as did the oven. But we wanted a new, flat top stove. I can't remember why, that was so long ago, but we did. So we bought a three-year-old, used one, that became new to us. The oven is terrible. At lower temperatures (350ish) it takes much longer to cook than what it should. We have had many meat and baking failures because of this. No, I have not purchased an oven temperature gauge because I know its wrong and I just have to cook things longer.
We had purchased a new washer and dryer when we got married. Over the years, my husband replaced many parts on them - motors, belts, heating elements etc, and they worked just fine. But the fancy, new, front loading machines sure looked nice! One Black Friday we saw an excellent deal at Sears and bought a pair (buy one, get one free.) Well, I have not been happy. We have to keep the door open on the washer so it doesn't mold. When I take things out of the washer they are still all entangled (you know, those long sleeve shirt sleeves and pants?) and I feel I am going to rip something in the process. Things fall on the floor routinely when emptying either one. Finally, socks and washcloths don't get dry even though everything else does. They are too small?
Next comes the refrigerator and water heater - you can almost repeat the above two paragraphs. They are worse than the old ones, which we thought needed replacing. Bottom line, I am afraid to buy a new appliance unless our current ones are so dead, or so expensive to fix that we could buy a new one for the same price. Thus, we still have our dishwasher and may it keep working, because I sure don't want to chance buying a new one!
