Diagnostic sequence – Stage 10
If the water level in the float 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 flash 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 flashing WTR LED can be cleared by
pressing the reset button.
