No Hot Water

I've replaced several Kitchen-Aid hot water dispensers because of no hot water. This time, I decided I'd dig deeper.

I noticed that the thermal fuse was the first item on the Part-Select list. I assumed it was the most frequently ordered part.

I removed the hot water tank from under the sink. I disassembled the tank and shell. I disassembled the tank and heating elelment. I tested the heating without the thermal fuse. I reassmbled the tank, replaced the thermal fuse, reassembled the tank and shell assemblly. Then I re-installed the entire heating unit back under the sink. Due to leaks, I had to redo the water supply connection. Then it worked fine! Note: I decided to replace the thermostat because the casing had become cracked and brittle. I ordered that seperately.

The exploded diagrams on the Part-Select site were extremely helpful in both diagnosing the problem and making the repair. Thanks for your help.
