What Check Water light flashing red means

On the GE Profile 15-inch undercounter clear ice machine UCC15 (Gourmet Clear Ice, models such as UCC15NJII and UCC15NPRII), a flashing red Check Water light means the water supply is low. The control checks for water every 20 minutes. When water returns, the machine resets on its own and goes back to making clear ice, so no button press is needed.

Common causes of Check Water light flashing red

Supply valve closed or partly closed
Kinked supply line behind the machine
Low household water pressure
Inlet valve not passing water

✓ One safe check you can try

1. Open the shutoff valve fully. 2. Check the supply line for kinks. 3. Restore the water supply. 4. Wait; the control checks every 20 minutes and resets automatically when water returns. Close the cabinet door afterward and check later for ice.

! Why to stop there

If the supply is confirmed good and the light keeps flashing, the inlet valve or water sensing is the area we test.
We check line pressure first, then the valve and the sensing.
A written price comes first.

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.

Check Water light flashing redCheck Water light flashing red questions

Why is Check Water flashing red on my clear ice machine?

The water supply is low. The machine cannot make clear ice without enough water. Clear ice needs a steady supply, so the machine waits for water.

Do I need to restart it?

No. The control checks for water every 20 minutes and resets automatically once water returns. This saves you from pressing buttons; just fix the supply and wait.

What if the light stays on?

Make sure the valve is open and the line is not pinched. If it still flashes, the inlet valve needs testing. We also check for a clogged inlet.
