If this happens, do not try to correct the fault yourself, but call for assistance.
3.1.2 The Water Pump for the Steam Generator
The water pump supplies the distilled or mineral-free water to the steam generator.
The supply line of the pump is connected to the upper water reservoir filled with distilled
or mineral-free water and mounted on side of the autoclave.
A float valve keeps a constant level of water and prevents an overflow of water out of the
reservoir.
A lower float switch stops the operation of pump, when the water level drops below the
lower level limit.
