Current appliance reliability
There has been, is, and always will be good appliances, and crappy appliances. Look at Westinghouse, WCI, or even late model Frigidaire machines. Westinghouse DWs in the early 70s were not that good, they didnt even have wheels on the lower rack, poorly rated by CR. Late model Frigidaire franklin machines have a tendency to leak, and that design has been around since the mid 80s. I don't like the adage "They sure don't make 'em like they used to!" because it is simply untrue. There has been, is, and always will be crappy products, just as there are good products. Perhaps the amount of quality machines 40 years ago was higher than today, but there still were garbage machines 40 years ago too.
It is really too soon to say how these new WP and GE machines with the impeller will turn out, as it is too early. Lets wait 10 years and then discuss.
As for why wouldn't WP keep the DC machine? Well, why would they? From a design perspective, the DC design is simple. Two screws and you are at most of the machine. No solenoids or massive clutch packs. Motor and pump are right infront of you, and the drive switching from agi to spin is also simple.
But then lets look at the DD machine. Its design is SIMPLE. More simple than the DC. Sometimes you have to remove two screws, or other times its just to clips, and then two more clips, and you are at the ENTIRE machine. Control panel, pump, motor, water level switch, transmission, brake, clutch, etc...
Being a die hard Maytag fan, who creams over older MT appliances, dreams about them etc... I will be the first one to admit, the DD washer is better than the DC machine. However, both machines are excellent performers, and where one machine lacks, the other one makes up for it. (Lets not forget, it took MT almost 40 years to add the extra rinse option LOL) I dont like MT fridges or stoves, since they aren't truely MT designs, as most of them were sourced from Norge/Magic Chef. Thats why I will always admire WP, its been a full-line manufacturer for many, many years, many many more years than Maytag.
