Nope - this is a two-speed machine, and it has the larger tub Maytag used at the time. When Maytag went to the second generation of this machine, they put four water level buttons on it instead of three like this one has, but they did not increase the capacity of the tub. So -
An early machine's buttons say, "Small, Normal and Large."
A second-generation machine's say, "Small, Medium, Normal and Large."
A third-generation machine's say, Small, Medium, Large and Extra Large."
Same capacity tub on all three generations. Just four fill levels on late machines instead of three as on earlier machines. Large (or Extra Large on third-generation machines) was a 19-gallon fill, 40 gallons total usage on all three generations. Where you gained a fill level was at the LOW end, where the Small on the later machines was smaller than the Small on the first generation.
Have I confused everyone enough, LOL?
