Low Medium High

Code Meaning Severity Common Symptom

HI High temperature alert High The ice maker halts its freezing cycle and produces no new ice because the evaporator cannot reach freezing temperature while the HI condition is active. View LEAK Water leak detected High Puddles or wet patches are present under or alongside the ice maker, indicating that water is escaping the normal water circuit during operation. View LO Low temperature alert Medium The ice maker stops completing cycles because the fill water freezes in the supply line before it can reach the ice tray, or the control logic suspends operation. View NO-ICE No ice production High The ice storage bin has been empty for an extended period even though the ice maker unit is powered on and appears to be operating. View PO Power outage detected Low Inspection of the ice mold reveals partially formed, cracked, or irregular ice cubes that resulted from the freeze cycle being interrupted mid-completion. View SLOW Slow ice production Low Each harvest cycle produces noticeably fewer or smaller ice cubes than the unit's rated output, meaning the bin fills much more slowly than expected. View
