I'm not sure I understand your fix. Do you mean put in a sort of block at the base of the frig? Ie- where the little black hose and frig drain hole is?
Sorry, I don't have a picture, but yes, pull that plastic fridge side grill off that the drain hose comes out of. (turn the slotted black plastic screws so slot is up & down, then yank on grill or may have to pry a bit at the bottom) You will see that the surrounding frame the grill fits into is flush at the bottom with a flat shelf where wiring etc goes through...check all the caulking for that shelf including the wiring holes. ....then use a piece of something non wood that will go inside that frame at the bottom on the shelf to make a lip, and then caulk it so that any water running down around that grill cannot run in onto that shelf area behind fridge because there is now a lip there to prevent it.
