Quick answer
The electronic board of a U-Line blast chiller detected a failure on relay 5. The manual says to call service.
Model compatibility: U-Line reuses codes across series and model years, so RELAY 5 BROKEN 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 electronic board detected a failure on relay 5; call service.
If your U-Line blast chiller flashes RELAY 5 BROKEN, the control board is telling you that relay 5 has failed. Under the manual’s instruction you call service.
Series involved
This alarm is listed for the touch screen controller on UCBF532, UCBF432, UCBF632, then UCBF659 and UCBF559.
Checking the alarm
Touch the ALARM tab during or after a cycle to view recorded alarms. Relay alarms are numbered, so make a note of the exact number. Unplugging the unit before any hands-on work is sensible, but relay faults are for a technician.
