Diagnostic sequence – Stage 10
If the water level in the float reservoir drops to an unacceptable level, the WTR LED goes out, shutting the
icemaker off. Also, the BT LED comes on, preventing the icemaker from restarting for twenty minutes. If water is
restored, the WTR LED comes back on and flashes to alert the technician that water to icemaker has been lost.
The icemaker restarts at the end of the 20 minute time delay. The flashing WTR LED can be cleared by pressing
the reset button.
