Better Top Load Washer
Hi Nick the KA is a better washer, but as you mentioned it is 10 years older and several parts like the timer and motor are harder to find if needed.
If it were me I would either keep what you have or if there is room have both hooked up and ready to use.
The only way I will use a TL washer any longer is if I can save and reuse the wash water usually by draining the water into a 2nd machine. To get decent cleaning out of a full fill TL machine you need around 20 gallons of hot water and a lot of detergent, it is simply too costly to dump all that down the drain after washing a few bath towels, sheets etc when you can use the slightly cooled water to wash wash your jeans etc.
The entire concept of TL washers was based on Wringer Washers where you filled up the machine with good hot water and got a good soap or detergent solution going and you set out to do at least several loads of laundry, the idea of dumping this water after a few lightly soiled things were washed would have been crazy to generations before us.
We have rebuild & resold a lot of these basic WP built TL DD washers, they are noisy and cheap sounding, sometimes I take the time to add sound deadening material to the inside of the cabinet and it makes an amazing difference.
