A fluid level detection device comprising an elongated shaft having a plurality of sensors and associated switches on a distal end thereof. The distal end of the shaft extends into a liquid reservoir with the switches configured to detect multiple predetermined fluid levels. The first fluid level detected is a warning level indicating that the level of fluid in the reservoir is low and results in a warning indication. The second fluid level detected is for a shutoff threshold that results in shutdown of the device using the fluid in the reservoir and a shutdown indicator.
