What Check Water light flashing red means

On the GE Profile 15-inch undercounter nugget ice machine UNC15 (models such as UNC15NJII and UNC15NPRII), a flashing red Check Water light means the water supply is low. The machine cannot fill its reservoir enough to make ice, so production stops and the bin may run empty. It is a supply condition, not a sign that the ice maker itself has failed.

Common causes of Check Water light flashing red

Water supply valve closed or partly closed
Supply line kinked or pinched behind the unit
Float valve not letting water in
Low household water pressure

✓ One safe check you can try

1. Open the water shutoff valve fully. 2. Check the supply line behind the machine for kinks. 3. Restore the water supply, including the float valve check. 4. Watch whether the light stops flashing and the machine starts making ice again.

! Why to stop there

If the supply is fine and the light still flashes, the inlet valve or float is the likely area.
We check pressure at the line, the inlet valve and the float.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
