I had a bad leak under my dishwasher, and it looks like the parts will be a fairly substantial cost, and I'd like to upgrade to a quieter model. However a wood floor was installed after the dishwasher and has effectively locked it into place (see photos). The adjusting feet cannot be reached to retract them, and there is no room to push it back first.
What type of tools or techniques can be used to get the dishwasher out and a new one installed? I'm thinking a chisel is about all that could work, and add some quarter round afterwards as needed to cover it up. Power routers require some circumferential clearance to work.
