Why you should not use antifreeze in the ice maker

As I posted recently I just changed out the nice maker assembly in my cockpit uline ice maker. Here is what the old one looked like. The PO used antifreeze to winterize which destroyed the coating and made it chip and corrode. Must always blow out the line from the valve to cabinet with air.

Ouch

How did you find that?  I'm guessing it jammed because the ice cubes would not release.

I changed out the ice maker because it was not working, not because of the chipped coating and corrosion. I was not having jamming issues. They work fine like this, it’s just kinda gross. In doing research I learned that antifreeze causes this

Yeah, that stuff is corrosive. Makes me wonder about putting it through an engine block. The sink drains in both my head and galley are all putted, I'm sure it's from the annual plumbing anti freeze treatment.

Agree Will. The PO of my boat did not use antifreeze in the water lines & heater, he blew them out with a compressor like RV's do and I plan to do that this fall. Of course, still need to pour antifreeze in to the sump box's, toilet, engines/genny, a/c, etc... Maybe he switched from antifreeze to air when he saw how that ice maker was pitting!
