Sorry but no
Whirlpool machines are 23 7/8", Bosch are 23 9/16".
Thus, the difference is not quite 1/3".
If the Bosch leaves a 3/4" gap, the Whirlpool will leave about a half inch of gap just as much.
None the less, both types of machines have flexible plastic pieces that act as buffer that cover any cabinet gaps that would exist.
If you manage to install any of these two types of machines with 3/4" gap (be that total or either side) you either have a 26" or larger DW space or just do not install DWs cause you are surely doing something incredibly wrong.
Also do NOT assume that ALL GE or FD DW do use brushed motors.
While the verry BOL might, anything mid to up-line should not have brushed motors.
Further it is a wise choice to mention that while the brands mentioned co offer products made in the US, Bosch does so as well.
Yet - to my knowledge at least - all manufacturers do use a lot of made in 'insert country with low wage' components anyway if not outsourcing BOL production entirely.
So take that with a grain of salt.
