Error codeBLACK OUT
ApplianceBlast Chiller
Quick answer
BLACK OUT is a power-interruption message on touch screen U-Line blast chillers.
Model compatibility: U-Line reuses codes across series and model years, so BLACK OUT 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
The system recorded a power interruption without switching off the display.
What BLACK OUT means
BLACK OUT tells you the system recorded a power interruption, and the display stayed on through it. It reports an event on the power supply side rather than a probe or part failure.
The manual lists no owner steps for this message.
Models
It appears in the alarm list for the UCBF432, UCBF532, UCBF632, UCBF559 and UCBF659 touch screen blast chillers.
If power drops keep repeating on your U-Line unit, talk to us at (310) 879-5776. Mention that BLACK OUT was shown, give the model number, and say when the interruptions happened. Our refrigeration service page has more detail.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
