Had/have similar problem; however when replacing our DW found that end
(over the DW) of one of the two fairly cheap 8 foot counter tops in
our kitchen was not that firmly fixed down. And it was possible with
assistance to pry up the counter top slightly and wangle the DW in
under it. This would not work with very heavy counter tops and/or one
might crack it????
Our alternative; if/when we redo our kitchen floor will probably be to
disassembled both of the lower counter cabinets and raise them
slightly; that may involve extending the plumbing slightly. Higher by
3/4 inch sounds like a lot! Having installed the cabinets myself some
40 years ago it should be possible.
Good luck.
