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

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.
