Error codeMAINTENAINCE
ApplianceBlast Chiller
Quick answer
The MAINTENAINCE alarm reminds the owner that a regular service inspection and preventive maintenance are due.
Model compatibility: U-Line reuses codes across series and model years, so MAINTENAINCE 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
Reminder to perform regular service inspection and preventive maintenance; call service.
The touch screen of a U-Line blast chiller can show MAINTENAINCE, spelled that way in the alarm list and sometimes written MAINTENANCE. It is a reminder, not a breakdown message: regular service inspection and preventive maintenance are due, and the manual says to call service.
Models
This alarm is listed for the touch screen controller on the UCBF432, UCBF532, UCBF632, UCBF559 and UCBF659.
Next step
Open the ALARM tab to see what has been recorded, then arrange the inspection with service.
Other alarms you may see
LOW TEMPERATURE: holding-cycle air temperature fell below the lower limit.
HIGH TEMPERATURE: holding-cycle air temperature rose above the higher limit.
