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.

Removed unit (disconnected both top water tubes) because unit was behind garbage disposer. Unplugged and Drained water from unit. Then removed thermostat cover and top cover from unit to access the thermal fuse. Removed the thermal fuse by disconnecting the two electrical spade connectors. Replaced thermal fuse, reassembly and reinstalled unit. Problem fixed; unit is again producing instant hot water.
