The dishwasher on the left . . .
. . . had a poor design (I had one) that caused the porcelain to rust through and leak. When Maytag discovered this flaw in the design, they offered a "kit" to repair the damage or offered a good trade-in toward the price of a new dishwasher. The original dishwasher was bought in 1972.
I chose the trade-in, received the new machine and never had a problem with it for I don't know how many years.
I had a friend who was re-doing a kitchen in a rent house, and I gave the dishwasher to him. I don't know whether or not it is still running.
I got myself a Hobart-built ISE which ran flawlessly until the main seal in the tub started decaying.
Never a complaint with either Maytag as far as cleaning ability. But I found the ISE capacity was greater, especially for items such as large cookie sheets.
