U-Line Clear Ice Maker Drain Blocked: LED 3 Flash Count and P60
A Drain Blocked message on a U-Line clear ice maker points to a stuck or overworked drain pump. LED 3 flashes, and one or two flashes show which circuit the board found open.
What does U-Line ice machine code Drain Blocked mean?
The CLR2060, the CLR2160 and the CO1224F are U-Line clear ice makers that can report Drain Blocked. The message tells you the drain pump is stuck or working beyond its limit, and LED 3 flashes to show it. Counting the flashes helps: one blink signals an open overflow circuit, and a double flash tells you a thermistor is open. The overflow case goes by the name P60. The machine stops making ice for as long as the light flashes.

How the ice machine detects Drain Blocked
On a clear ice machine, water that is not frozen has to leave the cabinet, and a drain pump handles that job. The control is built to notice when the pump cannot keep up or has stopped moving water. It reports this with LED 3, and the flashes carry extra information.
One flash means a protection circuit that guards against overflow has opened, which is the P60 condition. Two flashes mean a thermistor, a small temperature sensor, is open. In either case the control stops ice making, because freezing more water into a machine that cannot drain would only make matters worse. Interrupting power gives the control another look. If a hose was simply kinked or the outlet was blocked and has been cleared, the light settles down. If the pump or a circuit is the real cause, the flashing returns.
Likely causes of Drain Blocked
- The drain pump is jammed or carrying more than it can handle
- The overflow circuit has opened, which shows as one flash
- A thermistor circuit has opened, which shows as two flashes
Can you keep using the ice machine with Drain Blocked?
Leave the machine off while LED 3 is flashing. A pump pushed to keep running against a block can overheat, and a bin that cannot drain can overflow onto the floor. Count the flashes, check the hose for a kink, and clear what you can see. If the pattern comes back, keep it unplugged until the pump and the circuits have been tested.
What you can safely check
- Switch the machine off and unplug it so the pump and the drain are safe to inspect.
- Count the LED 3 flashes before power is removed and write the number down.
- Look at the drain hose for a kink or a crushed section.
- Look at the drain outlet and clear away anything in its way.
- Plug it in and switch it on, then contact us if LED 3 flashes again.
What our technician does for Drain Blocked
- Use the flash count to decide which circuit to test first
- Test the drain pump and clear any blockage
- Check the overflow circuit and the thermistor with a meter
- Confirm the light stays steady after the repair
How to keep Drain Blocked from coming back
- Keep the drain hose straight and clear of anything that could crush it.
- Make sure the drain outlet stays free of debris, scale and leaves.
- Where the water is hard, ask us about cleaning routines that keep the pump from clogging.

Drain Blocked questions
Why does the number of LED 3 flashes matter?
The count narrows the search. A single flash tells us the overflow circuit is open, and a double flash tells us a thermistor is open. Both sit under the Drain Blocked message, so we know which test to run first.
Where does the name P60 come from?
P60 is the name for the overflow condition. It belongs to the one-flash pattern on these clear ice models, so P60 and one flash describe the same event.
Will a dry bin make the flashing stop?
Not by itself. Emptying the bin does nothing for a pump or circuit problem. Straightening a kinked hose is worth doing, yet a flash pattern that repeats needs a test of the pump circuit.
Is Drain Blocked the same message as LED 3 on the combination machine?
They are close but not identical. Both involve LED 3 and the drain pump. The names and models differ, so give us your exact model and the number of flashes to help us start in the right place.
What should I tell you when I describe it?
Tell us the model, the number of LED 3 flashes you counted, and whether water is standing in the bin. That helps us bring the right parts and decide which circuit to test first.
