Was wondering if anyone was considering how to get an indication water is getting low in the tank before the machine actually runs out of water and shuts off????
I am thinking out loud here...
I was considering the possibility of putting a 110 volt (2 wire) flasher module in series with the power to one (or both if wiring permits) of the green power lights that show the boiler heaters are turned on. The flasher would be hooked in series with the original wiring to the bulb(s) and then another magnetic float switch similar, if not identical to the main low water cut off, would be added to the tank. The magnetic float switch would be wired across the flasher to prevent the lights from flashing until water level in the tank drops low enough for the magnetic switch to open. The sole purpose of this added circuit is to let you know you have enough water left to do one or two shots and then your going to shut down.
This is assuming the lights are 110 volts (I haven't checked).
The two wire 110 volt flasher module is in the $10 to $12 range... don't know what another float switch kit would cost... might be best just to order the pats from QM. Probably about an hour long project for most people.
