I have an under counter ice machine from Kitchen Aid. U was going to clean it, but it took overnight for the water to drain. I used a small brush to try to unclog the drain and some yellow gunk came out, but eventually the water drained. Before I put the cleaner in, I poured warm water in the machine to see if it drained, but it didn't! So, I was going to try to clean the tubing that goes from the unit to the drain in the sink next to it, but I don't know how or what I should do. I turned the water valve off, then got lost!
What do I do next?
