My macerator wouldn't come on from first trip out. Brought unit back for this and a few other things. Dealer told me he found no fuse in the panel and then no wire behind fuse. He had to run a wire to fuse panel from switch as this was forgotten when built. Humm. After that, on next trip it worked great. No mess, no hoses to break loose and rinse.
