U-Line 1000 Series Clear Ice Code Pi: Pump Circuit Open

What Pi means

On the U-Line 1000 Series clear ice maker UCLR1215, the display prints Pi when the pump circuit is open. The characters read like P1, and they mean the same thing: the control cannot read the water pump circuit as complete. Ice making stops because the machine has no water circulation, and Pi stays on the display until the circuit reads normal.

Common causes of Pi

The pump circuit reads open
The pump has stopped working
The drain path is restricted

✓ One safe check you can try

1. Switch the ice maker off for several minutes. 2. Check behind the unit that the drain hose is straight. 3. Make sure nothing is leaning on the hose. 4. Switch the machine back on. 5. If Pi comes back, leave it off and call us.

! Why to stop there

The same display comes from a drain problem or a pump problem
Running a clear ice maker without water movement harms it

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.

PiPi questions

Why does my clear ice maker show Pi and not P1?

The UCLR1215 prints this code as Pi, so that is what you read on the display. It is the same pump circuit open message the nugget models show as P1.

Will it make ice while Pi shows?

No. Clear ice depends on water circulating over the plate, and the pump circuit is the part the control cannot confirm. Output pauses until the circuit reads normal.

Can I reset Pi myself?

Switching the machine off for a few minutes is safe. If Pi returns, the circuit still reads open, and we test the pump and drain path to find which part needs replacing.
