Error codeEr15
ApplianceIce Maker
Quick answer
Er15 is a water supply error on the RNP115 / URNP115 nugget ice machine. The manual lists a pressure check and a sensor check.
Model compatibility: U-Line reuses codes across series and model years, so Er15 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Water supply error: the water level sensor detects no water for 2 minutes, and the error resets automatically after 5 minutes.

What the manual says to do
Check the water supply pressure.

Start operation again once both checks are done.
