Evan,
I'm not familiar with your unit.... but if you look at the bathroom sink cabinet, the bottom panel seems to have screws holding it in.... now look in the kitchen... any panels with screws there?? The fresh water fill looks to be in that vicinity ( on the exterior) and I would think the fresh tank is under the floor there.... so your pump "should" be around there. Dutchman puts them behind counter panels...
I would think you would not have to cut thru anything to access it.... good hunting!
