U-Line Ice Maker Error Code Drain Blocked

The Drain Blocked error means the drain pump has detected a problem moving water out of the unit. This is typically caused by a restricted or kinked drain hose, a clogged drain pump impeller, or a failed pump motor. The machine will halt normal operation until the drainage path is restored.

A reset alone will not permanently clear this error if the underlying drainage problem has not been addressed. The unit may resume briefly after a reset, but the fault will return if the drain hose remains blocked or the pump is still malfunctioning. Resolve the physical cause first, then reset the unit.

Repair costs depend on the cause. Clearing a kinked hose or cleaning a scaled impeller typically involves no parts cost and minimal labor. Replacing a failed drain pump generally ranges from around $80 to $200 or more depending on the part and whether a technician performs the repair. Professional diagnostic service calls typically add $75 to $150 to the total.

Start by inspecting the drain hose for kinks, clogs, or a blocked outlet connection. If the hose is clear, check the drain pump for correct operation by confirming the impeller spins freely and the pump activates when commanded. Clean any mineral scale from the impeller and internal drain port. If the pump motor has failed, it will need to be replaced.

Continuing to run the ice maker with an active drain blockage is not recommended. Water that cannot drain properly can back up into the unit, overflow into surrounding cabinetry, or create conditions for mold growth. Address the drainage issue before resuming normal use.
