First thing is that I'm replacing the water supply line. The old plastic line was chewed through by thirsty rodents, so I'm replacing it with copper.
Then comes the replacing of the inline filter. That's all the easy stuff.
The icemaker itself works fine when the water gets to it. I think the solenoid valve is clogged, so that's one of the next steps. One way or another, that fucker will be working by tomorrow morning.
Edit: all finished. Now I just have to wait for ice.
