What you may notice with CLRCO2075 LED 3 flashing

• Ice making has stopped and the bin gets no new ice.
• Water may be building up inside the bin.
• The drain line may be bent or squeezed behind the unit.

How the ice machine detects CLRCO2075 LED 3 flashing

This clear ice machine makes ice by freezing water and then melting a little away, so it always has water to send down a drain. A small pump moves that water out of the bin. The first-generation Echelon board monitors the pump, and when the pump is blocked or is working too hard, the board sets LED 3 to flash.

The board treats a pump that cannot clear the water as a reason to stop. If it kept making ice, more water would reach the bin and could spill. So it halts ice making and waits. The flashing continues until power is removed and the board checks again. A blocked drain line, a pump carrying too much, or a drain that was routed poorly when the unit was installed can all lead to the same pattern. A gallon of water poured in shows whether the drain really works.

Likely causes of CLRCO2075 LED 3 flashing

• The drain line has a clog or a kink that holds water back
• The drain pump is overloaded by more water than it can move
• The way the drain was routed at installation keeps water from leaving

Can you keep using the ice machine with CLRCO2075 LED 3 flashing?

Do not run the machine while water is building up in the bin, since it can overflow and wet the cabinet and the floor. Unplug it, check for an obvious kink, and test the drain with a gallon of water. If the water will not drain, leave the unit off and have the line and the pump looked at, rather than resetting it again and again.

What you can safely check

1. Unplug the machine before you reach toward the bin or the drain.
2. Follow the drain line and look for kinks or clogs you can see.
3. Straighten any visible kink, then plug the machine back in.
4. Put a gallon of water in the bin and see if it leaves.
5. If LED 3 starts flashing again, contact us.

How to keep CLRCO2075 LED 3 flashing from coming back
