If the water level in the  oat reservoir drops to an unacceptable level, the WTR LED will go out, shutting the ice
machine off. Also, the BT LED will come on, preventing the ice machine from restarting for twenty minutes. If
water is restored, the WTR LED will come back on and  ash to alert the technician that water to ice machine has
been lost. The ice machine will then restart at the end of the 20 minute time delay. The  ashing WTR LED can be
cleared by pressing the reset button.
