Removed the heater from under the sink by shutting off the cold water valve and disconnecting the water in and out connections, and the power plug. Disassembled the Instanthot making note of the original wiring connections. Noted the heat fuse which I assumed had blown. To confirm I bypassed the thermostat and fuse wire, plugged in the unit and found it heating rapidly.
Checked on the partselect web site, identified the heat fuse and ordered same. After arrival, I easily replaced the fuse, re-wrapped the heater with the insulating blanket being careful to keep all wires outside the blanket and away from touching the heater. Reassembled the heater and reconnected the unit beneath the sink. Bingo!! Hot water again.
