I was dumb and left water dispenser valve open on my Alex Leva.

Then it turned on automatically in the morning and emptied self, and emptied the bottle water supply, and now the heating element won't turn on. I'm hoping problem is that safety thermostat needs to be switched, but I can't seem to find it.

Does anyone know where and how to reset thermostat on Alex Leva?

Found it. It was a small white button under the machine.

Yes, thermostat reset fixed.
