I have been following this thread and will comment on what little I know.
On the old site I posted some information on replacement of the old
see-thru bowl with four pins (two for the water sensor probe and two
for the heater), with the two pin bowl currently available. If you
can find it or if someone can point you to it you may find it relevant.
The heater is essential at low temperature (20 or less?), you should
eventually replace it. Sounds as if the integral thermostat did not
shut off and cooked the internal components.
